10716-520: The clergy, the law profession, and the aristocracy and he sent thousands of sets out in the first year or so, in 1874." The world's oldest annual tennis tournament took place at Leamington Lawn Tennis Club in Birmingham in 1874. This was three years before the All England Lawn Tennis and Croquet Club would hold its first championships at Wimbledon, in 1877. The first Championships culminated in
10857-437: The country where the last tie between the teams was not held. In case the two countries have not met since 1970, lots are drawn to determine the host country. Venues in the World Group must comply with certain minimum standards, including a minimum seating capacity as follows: Prior to each tie, the captain (non-playing coach appointed by the national association) nominates a squad of four players and decides who will compete in
10998-424: The court). The short mark in the centre of each baseline is referred to as either the hash mark or the centre mark. The outermost lines that make up the length are called the doubles sidelines; they are the boundaries for doubles matches. The lines to the inside of the doubles sidelines are the singles sidelines, and are the boundaries in singles play. The area between a doubles sideline and the nearest singles sideline
11139-399: The credit for the development of modern tennis." According to Honor Godfrey, museum curator at Wimbledon, Wingfield "popularized this game enormously. He produced a boxed set which included a net, poles, rackets, balls for playing the game – and most importantly you had his rules. He was absolutely terrific at marketing and he sent his game all over the world. He had very good connections with
11280-433: The cup after India refused to travel to South Africa in protest of South Africa's apartheid policies. The following year saw the first actual final between two "outsider" nations, when Sweden beat Czechoslovakia 3–2, and since then, many other countries have gone on to capture the trophy. All contract professionals were not allowed to play in the Davis Cup until 1973. The tennis stars who turned professional prior to
11421-408: The defending champion was required to compete in all rounds, and the Davis Cup was awarded to the champion. Up until 1973 , the Davis Cup had only ever been won by the United States, Great Britain/British Isles, France and Australia/Australasia. Their domination was eventually broken in 1974 when South Africa and India made the final; however, the final was scratched and South Africa was awarded
11562-426: The doubles rubber: the two singles players, two other players (usually doubles specialists) or a combination. Each rubber is normally played as best of five sets . Since 2016 , all sets use a tiebreak at 6–6 if necessary (formerly, the fifth set usually had no tiebreaker, so play continued until one side won by two games e.g. 10–8). However, if a team has clinched the tie before all five rubbers have been completed,
11703-409: The female counterpart of Harvard College, becoming one of the most prominent schools in the nation for women. In 1923, a year after the percentage of Jewish students at Harvard reached 20%, A. Lawrence Lowell , the university's 22nd president, unsuccessfully proposed capping the admission of Jewish students to 15% of the undergraduate population. Lowell also refused to mandate forced desegregation in
11844-466: The final round. Beginning in 1923 , the world's teams were split into two zones: the "America Zone" and the "Europe Zone". The winners of the two zones met in the Inter-Zonal Zone ("INZ") to decide which national team would challenge the defending champion for the cup. In 1955 a third zone, the "Eastern Zone", was added. Because there were three zones, the winner of one of the three zones received
11985-462: The first lawn mower in Britain in 1830 is believed to have been a catalyst for the preparation of modern-style grass courts, sporting ovals, playing fields, pitches, greens, etc. This in turn led to the codification of modern rules for many sports, including lawn tennis, most football codes, lawn bowls and others. Between 1859 and 1865, Harry Gem , a solicitor, and his friend Augurio Perera developed
12126-442: The first day's singles rubbers. However, in certain circumstances, the team captain may replace one or two of the players who played the singles on Friday by other players who were nominated for the tie. For example, if the tie has already been decided in favour of one of the teams, it is common for younger or lower-ranked team members to play the remaining dead rubbers in order for them to gain Davis Cup experience. Since 2011, if
12267-459: The first time since 1962 (for Laver) and since 1956 (for Rosewall). In 1981 , a tiered system of competition was created, in which the 16 best national teams compete in the World Group and all other national teams compete in one of four groups in one of three regional zones. In 1989 , the tiebreak was introduced into Davis Cup competition, and from 2016 it is used in all five sets. In 2018,
12408-497: The following guidelines; The rules regarding rackets have changed over time, as material and engineering advances have been made. For example, the maximum length of the frame had been 32 inches (81 cm) until 1997, when it was shortened to 29 inches (74 cm). Many companies manufacture and distribute tennis rackets. Wilson, Head and Babolat are three of the most commonly used brands; however, many more companies exist. The same companies sponsor players to use these rackets in
12549-455: The following year, a struggle broke out over their replacements. In 1805, Henry Ware was elected to replace Tappan as Hollis chair. Two years later, in 1807, liberal Samuel Webber was appointed as Harvard's 13th president, representing a shift from traditional ideas at Harvard to more liberal and Arminian ideas. In 1816, Harvard University launched new language programs in the study of French and Spanish , and appointed George Ticknor
12690-507: The following year. In 1638, the university acquired British North America 's first known printing press . The same year, on his deathbed, John Harvard , a Puritan clergyman who emigrated to the colony from England, bequeathed the emerging college £780 and his library of some 320 volumes; the following year, it was named Harvard College . In 1643, a Harvard publication defined the college's purpose: "advance learning and perpetuate it to posterity, dreading to leave an illiterate ministry to
12831-529: The four recipient nations to replace the "world championships" with "official championships" was simple in a general sense: each became a major nation of the federation with enhanced voting power, and each now operated a major event. The comprehensive rules promulgated in 1924 by the ILTF have remained largely stable in the ensuing 80 years, the one major change being the addition of the tiebreak system designed by Jimmy Van Alen . That same year, tennis withdrew from
12972-404: The game (tying the set 6–6) a tiebreak is played. A tiebreak, played under a separate set of rules, allows one player to win one more game and thus the set, to give a final set score of 7–6. A tiebreak game can be won by scoring at least seven points and at least two points more than the opponent. In a tiebreak, two players serve by 'ABBA' system which has been proven to be fair. If a tiebreak
13113-411: The game has break point , double break point or triple break point , respectively. If the receiver does, in fact, win their break point, the game is awarded to the receiver, and the receiver is said to have converted their break point. If the receiver fails to win their break point it is called a failure to convert. Winning break points, and thus the game, is also referred to as breaking serve , as
13254-635: The groups and the two best second places advancing to quarterfinals. The series between the teams in this stage will feature two singles matches and one doubles match, instead of the best-of-5 series, with the matches changing from best of 5 sets to best of 3. As the World Group will now take place as one single competition, this event has been named as the Davis Cup Finals. The lower zone groups I and II will be composed of single ties deciding promotion or relegation. Note: The total number of nations in Group One
13395-501: The hand. Louis X of France was a keen player of jeu de paume ("game of the palm"), which evolved into real tennis , and became notable as the first person to construct indoor tennis courts in the modern style. Louis was unhappy with playing tennis outdoors and accordingly had indoor, enclosed courts made in Paris "around the end of the 13th century". In due course this design spread across royal palaces all over Europe. In June 1316 at Vincennes , Val-de-Marne, and following
13536-565: The hopes that the company name will become better known by the public. There are multiple types of tennis strings, including natural gut and synthetic stings made from materials such as nylon , kevlar , or polyester . The first type of tennis strings available were natural gut strings, introduced by Babolat. They were the only type used until synthetic strings were introduced in the 1950s. Natural gut strings are still used frequently by players such as Roger Federer. They are made from cow intestines, and provide increased power, and are easier on
13677-480: The idea, which was tentatively agreed, and he ordered an appropriate sterling silver punchbowl trophy from Shreve, Crump & Low , purchasing it from his own funds for about US$ 1,000. They in turn commissioned a classically styled design from William B. Durgin 's of Concord, New Hampshire , crafted by the Englishman Rowland Rhodes. Beyond donating a trophy for the competition, Davis's involvement in
13818-401: The incipient development of the team competition that came to bear his name was negligible, yet a persistent myth has emerged that Davis devised both the idea for an international tennis competition and its format of mixing singles and doubles matches. Research has shown this to be a myth, similar in its exaggeration of a single individual's efforts within a highly complex long-term development to
13959-552: The largest university endowment in the world, valued at about $ 50.7 billion as of 2023. During the recession of 2007–2009 , it suffered significant losses that forced large budget cuts, in particular temporarily halting construction on the Allston Science Complex. The endowment has since recovered. About $ 2 billion of investment income is annually distributed to fund operations. Harvard's ability to fund its degree and financial aid programs depends on
14100-506: The late 19th century, Harvard University's graduate schools began admitting women in small numbers. In 1900, Harvard became a founding member of the Association of American Universities . For the first few decades of the 20th century, the Harvard student body was predominantly "old-stock, high-status Protestants , especially Episcopalians , Congregationalists , and Presbyterians ," according to sociologist and author Jerome Karabel . Over
14241-509: The losing teams facing relegation to the next-lower group. The teams in Groups III and those in Group IV play a round-robin event with promotion and relegation. For the 2019 edition , the format of the cup is changed. The main modification is the World Group taking place at one location and in one week, with eighteen teams divided in six round-robin groups of three teams each, with the winners of
14382-543: The main campus in Cambridge are the Law , Divinity (theology), Engineering and Applied Science , Design (architecture), Education , Kennedy (public policy), and Extension schools, and Harvard Radcliffe Institute in Radcliffe Yard. Harvard also has commercial real estate holdings in Cambridge. Harvard Business School , Harvard Innovation Labs , and many athletics facilities, including Harvard Stadium , are located on
14523-553: The mains (the vertical strings) and the crosses (the horizontal strings). This is most commonly done with two different strings that are made of different materials, but can also be done with two different types of the same string. A notable example of a player using hybrid strings is Roger Federer, using natural gut strings in his mains and polyester strings in his crosses. Tennis balls were originally made of cloth strips stitched together with thread and stuffed with feathers. Modern tennis balls are made of hollow vulcanized rubber with
14664-480: The myths of William Webb Ellis and Abner Doubleday , who have both been wrongly credited with inventing rugby and baseball, respectively. Davis nevertheless went on to become a prominent politician in the United States in the 1920s, serving as US Secretary of War from 1925 to 1929 and as Governor-General of the Philippines from 1929 to 1932. The first match, between the United States and Britain (competing as
14805-399: The net. A player or team cannot hit the ball twice in a row. The ball must travel over or round the net into the other players' court. A ball that hits the net during a rally is considered a legal return as long as it crosses into the opposite side of the court. The first player or team to fail to make a legal return loses the point. The server then moves to the other side of the service line at
14946-408: The official ITF list of approved tennis balls. Tennis is played on a rectangular, flat surface. The court is 78 feet (23.77 m) long, and 27 feet (8.2 m) wide for singles matches and 36 ft (11 m) for doubles matches. Additional clear space around the court is required in order for players to reach overrun balls. A net is stretched across the full width of the court, parallel with
15087-411: The older racket sport today called real tennis . The rules of modern tennis have changed little since the 1890s. Two exceptions are that until 1961 the server had to keep one foot on the ground at all times, and the adoption of the tiebreak in the 1970s. A recent addition to professional tennis has been the adoption of electronic review technology coupled with a point-challenge system, which allows
15228-530: The performance of its endowment; a poor performance in fiscal year 2016 forced a 4.4% cut in the number of graduate students funded by the Faculty of Arts and Sciences . Endowment income is critical, as only 22% of revenue is from students' tuition, fees, room, and board. Since the 1970s, several student-led campaigns have advocated divesting Harvard's endowment from controversial holdings, including investments in South Africa during apartheid , Sudan during
15369-488: The player who is in the lead in the game needs only one more point to win the game. The terminology is extended to sets (set point), matches (match point), and even championships (championship point). For example, if the player who is serving has a score of 40–love, the player has a triple game point (triple set point, etc.) as the player has three consecutive chances to win the game. Game points, set points, and match points are not part of official scoring and are not announced by
15510-410: The player's scores equal at 40 apiece, the score is not called out as "40–40", but rather as "deuce". If at least three points have been scored by each side and a player has one more point than his opponent, the score of the game is "advantage" for the player in the lead. During informal games, advantage can also be called "ad in" or "van in" when the serving player is ahead, and "ad out" or "van out" when
15651-432: The pressure. Harvard is a large, highly residential research university offering 50 undergraduate majors, 134 graduate degrees, and 32 professional degrees. During the 2018–2019 academic year, Harvard granted 1,665 baccalaureate degrees, 1,013 graduate degrees, and 5,695 professional degrees. Harvard College , the four-year, full-time undergraduate program, has a liberal arts and sciences focus. To graduate in
15792-449: The receiver has disrupted, or broken the natural advantage of the server. If in the following game the previous server also wins a break point it is referred to as breaking back . Except where tiebreaks apply, at least one break of serve is required to win a set (otherwise a two-game lead would never occur). Another, however informal, tennis format is called Canadian doubles . This involves three players, with one person playing against
15933-414: The receiving player is ahead; alternatively, either player may simply call out "my ad" or "your ad". The score of a tennis game during play is always read with the serving player's score first. In tournament play, the chair umpire calls the point count (e.g., "15–love") after each point. At the end of a game, the chair umpire also announces the winner of the game and the overall score. A set consists of
16074-566: The reform was also mixed among current and former players, with some such as Novak Djokovic and Rafael Nadal being in favour of the new format, but others such as Rod Laver , Lucas Pouille and Roger Federer being opposed. On 12 January 2023, the ITF announced that the partnership with the new promoter ends and that ITF is taking back the control of the event. Davis Cup games have been affected by political protests several times, especially in Sweden: Russia and Belarus were suspended after
16215-531: The remaining rubbers may be shortened to best of three sets, with a tiebreak if necessary to decide all three sets. In Group III and Group IV competitions, each tie consists only of three rubbers, which include two singles and one doubles rubber, which is played in a single day. The rubbers are in the best of three sets format, with a tie breaker if necessary to decide all three sets. (1981–2018) For more information, see ITF rankings Change since previous ranking update Tennis Tennis
16356-404: The service boxes; depending on a player's position, they have to hit the ball into one of these when serving. A ball is out only if none of it has hit the area inside the lines, or the line, upon its first bounce. All lines are required to be between 1 and 2 inches (25 and 51 mm) in width, with the exception of the baseline which can be up to 4 inches (100 mm) wide, although in practice it
16497-417: The singles court on each side. The modern tennis court owes its design to Major Walter Clopton Wingfield . In 1873, Wingfield patented a court much the same as the current one for his stické tennis (sphairistike). This template was modified in 1875 to the court design that exists today, with markings similar to Wingfield's version, but with the hourglass shape of his court changed to a rectangle. Tennis
16638-536: The standard Davis Cup format, mixing single and doubles matches, and in 1895 England played against France in a national team competition. During Larned's tour of the British Isles in 1896, where he competed in several tournaments including the Wimbledon Championships , he was also a spectator for the annual England vs. Ireland match. He returned to exclaim that Britain had agreed to send a group of three to
16779-468: The start of a new point. A game consists of a sequence of points played with the same player serving. A game is won by the first player to have won at least four points in total and at least two points more than the opponent. The running score of each game is described in a manner peculiar to tennis: scores from zero to three points are described as "love", "15", "30", and "40", respectively. If at least three points have been scored by each player, making
16920-413: The start of the Open Era . The idea for an event pitting the best British and Americans in competition against one another was probably first conceived by James Dwight , the first president of the U.S. National Lawn Tennis Association when it formed in 1881. Desperate to assess the development of American players against the renowned British champions, he worked tirelessly to engage British officials in
17061-529: The summer of 1899, that four members of the Harvard University tennis team—Dwight Davis included—travelled across the States to challenge the best west-coast talent, and upon his return, it apparently occurred to Davis that if teams representing regions could arouse such great feelings, then why wouldn't a tennis event that pitted national teams in competition be just as successful. He approached James Dwight with
17202-423: The surrounding Harvard Square neighborhood. The Yard houses several Harvard buildings, including four of the university's libraries, Houghton , Lamont , Pusey , and Widener . Also on Harvard Yard are Massachusetts Hall , built between 1718 and 1720 and the university's oldest still standing building, Memorial Church , and University Hall Harvard Yard and adjacent areas include the main academic buildings of
17343-455: The tenets of Puritanism. In 1650, the charter for Harvard Corporation , the college's governing body, was granted. From 1681 to 1701, Increase Mather , a Puritan clergyman, served as Harvard's sixth president . In 1708, John Leverett became Harvard's seventh president and the first president who was not also a clergyman. Harvard faculty and students largely supported the Patriot cause during
17484-421: The tie is the nation which wins three or more of the five rubbers in the tie. On the first day, the first two rubbers are singles , which are generally played by each nation's two best available singles players. On the second day, the doubles rubber is played. On the third day, the final two rubbers are typically reverse singles , in which the first-day contestants usually play again, but they swap opponents from
17625-431: The tie. On the day before play starts, the order of play for the first day is drawn at random. In the past, teams could substitute final day singles players only in case of injury or illness, verified by a doctor, but current rules permit the captain to designate any player to play the last two singles rubbers, provided that no first day matchup is repeated. There is no restriction on which of the playing team members may play
17766-559: The time was right for a properly sanctioned international competition. This was to be staged in Newcastle in July 1898, but the event never took place as the Americans could not field a sufficiently strong team. A reciprocal tour to the U.S. in 1899 amounted to just a single British player travelling overseas, as many of the players were involved in overseas armed conflicts. It was at this juncture, in
17907-492: The top two seeds in the event. The losers of the first-round matches are sent to the World Group playoff round, where they play along with winners from Group I of the regional zones. The playoff round winners play in the World Group for the next year's competition, while the losers play in Group I of their respective regional zone. Each of the three regional zones is divided into four groups. Groups I and II play elimination rounds, with
18048-494: The top universities in the world in each of these categories. Harvard students and alumni have also collectively won 10 Academy Awards and 110 Olympic medals , including 46 gold. Harvard was founded in 1636 during the colonial , pre- Revolutionary era by vote of the Great and General Court of Massachusetts Bay Colony , one of the original Thirteen Colonies of British America . Its first headmaster, Nathaniel Eaton , took office
18189-414: The two nations, and an ensuing friendship between American William Larned and Irishman Harold Mahony spurred efforts to formalize an official team competition between the two nations. International competitions had been staged for some time before the first Davis Cup match in 1900. From 1892, England and Ireland had been competing in an annual national-team-based competition, similar to what would become
18330-498: The undergraduate college became accessible to striving middle class students from public schools; many more Jews and Catholics were admitted, but still few Blacks, Hispanics, or Asians versus the representation of these groups in the general U.S. population. Over the second half of the 20th century, however, the university became incrementally more diverse. Between 1971 and 1999, Harvard controlled undergraduate admission, instruction, and housing for Radcliffe's women; in 1999, Radcliffe
18471-400: The university's freshman dormitories , writing that, "We owe to the colored man the same opportunities for education that we do to the white man, but we do not owe to him to force him and the white into social relations that are not, or may not be, mutually congenial." Between 1933 and 1953, Harvard University was led by James B. Conant , the university's 23rd president, who reinvigorated
18612-428: The university's creative scholarship in an effort to guarantee Harvard's preeminence among the nation and world's emerging research institutions. Conant viewed higher education as a vehicle of opportunity for the talented rather than an entitlement for the wealthy, and devised programs to identify, recruit, and support talented youth. In 1945, under Conant's leadership, an influential 268-page report, General Education in
18753-531: The university's first professor for these language programs. From 1869 to 1909, Charles William Eliot , Harvard University's 21st president, decreased the historically favored position of Christianity in the curriculum, opening it to student self-direction. Though Eliot was an influential figure in the secularization of U.S. higher education, he was motivated primarily by Transcendentalist and Unitarian convictions influenced by William Ellery Channing , Ralph Waldo Emerson , and others, rather than secularism. In
18894-500: The usual four years, undergraduates normally take four courses per semester. In most majors, an honors degree requires advanced coursework and a senior thesis. Though some introductory courses have large enrollments, the median class size is 12 students. The Faculty of Arts and Sciences , with an academic staff of 1,211 as of 2019, is the largest Harvard faculty, and has primary responsibility for instruction in Harvard College ,
19035-530: The wall. Henry VIII of England was a big fan of this game, which is now known as real tennis . An epitaph in St Michael's Church, Coventry , written c. 1705 , read, in part: Here lyes an old toss'd Tennis Ball: Was racketted, from spring to fall, With so much heat and so much hast, Time's arm for shame grew tyred at last. During the 18th and early 19th centuries, as real tennis declined, new racket sports emerged in England. The invention of
19176-472: The war. The university has ten academic faculties and a faculty attached to Harvard Radcliffe Institute . The Faculty of Arts and Sciences offers study in a wide range of undergraduate and graduate academic disciplines , and other faculties offer graduate degrees, including professional degrees. Harvard has three campuses: the main campus, a 209-acre (85 ha) in Cambridge centered on Harvard Yard ; an adjoining campus immediately across Charles River in
19317-775: The world was formed, the United States National Lawn Tennis Association (now the United States Tennis Association ) in order to standardize the rules and organize competitions. The US National Men's Singles Championship, now the US Open , was first held in 1881 at the Newport Casino , Newport, Rhode Island . The US National Women's Singles Championships were first held in 1887 in Philadelphia . Tennis also became popular in France, where
19458-460: Was appointed interim president. In August 2024, the university announced that Garber would be appointed Harvard's 31st president through the end of the 2026–27 academic year. The 209-acre (85 ha) main campus of Harvard University is centered on Harvard Yard , colloquially known as "the Yard," in Cambridge, Massachusetts , about 3 miles (5 km) west-northwest of downtown Boston , and extending to
19599-454: Was formally merged into Harvard University. On July 1, 2007, Drew Gilpin Faust , dean of Harvard Radcliffe Institute , was appointed Harvard's 28th and the university's first female president. On July 1, 2018, Faust retired and joined the board of Goldman Sachs , and Lawrence Bacow became Harvard's 29th president . In February 2023, approximately 6,000 Harvard workers attempted to organize
19740-469: Was in attendance at this tournament, and was thought to have got wind of the idea as it was discussed in the tournament's popular magazine, and Davis's name was mentioned as someone who might 'do something for the game ... put up some big prize, or cup'. Larned and Fischer met on several occasions that summer and discussed the idea of an international match to be held in Chicago the following summer, pitting six of
19881-502: Was played there in September 1880. An Englishman named O.E. Woodhouse won the singles title, and a silver cup worth $ 100, by defeating Canadian I. F. Hellmuth . There was also a doubles match which was won by a local pair. There were different rules at each club. The ball in Boston was larger than the one normally used in New York. On 21 May 1881, the oldest nationwide tennis organization in
