During the twentieth century, Harvard's international reputation grew as a burgeoning endowment and prominent professors expanded the university's scope. Explosive growth in the student population continued with the addition of new graduate schools and the expansion of the undergraduate program. Radcliffe College, established in 1879 as sister school of Harvard College, became one of the most prominent schools for women in the United States.

James Bryant Conant (president, 1933–1953) reinvigorated creative scholarship to guarantee its preeminence among research institutions. He saw higher education as a vehicle of opportunity for the talented rather than an entitlement for the wealthy, so Conant devised programs to identify, recruit, and support talented youth. In 1943, he asked the faculty make a definitive statement about what general education ought to be, at the secondary as well as the college level. The resulting Report, published in 1945, was one of the most influential manifestos in the history of American education in the 20th century.

In 1945-1960 admissions policies were opened up to bring in students from a more diverse applicant pool. No longer drawing mostly from rich alumni of select New England prep schools, the undergraduate college was now open to striving middle class students from public schools; many more Jews and Catholics were admitted, but few blacks, Hispanics or Asians.

Harvard and its affiliates, like many American universities, are considered by some to be politically liberal (left of center).[28] Conservative author William F. Buckley, Jr. quipped that he would rather be governed by the first 2000 names in the Boston phone book than by the Harvard faculty, Richard Nixon famously referred to Harvard as the "Kremlin on the Charles" around 1970, and Vice President George H.W. Bush disparaged what he saw to be Harvard's liberalism during the 1988 presidential election.[31] Republicans remain a small minority of faculty, and the University has refused to officially recognize the Reserve Officers' Training Corps (ROTC) program — forcing students to commission through nearby MIT.The Harvard College Handbook explains, "Current federal policy of excluding known lesbian, gay, and bisexual individuals from admission to ROTC or of discharging them from service is inconsistent with Harvard’s values as stated in its policy on discrimination."

President Lawrence Summers resigned his presidency in 2006. His resignation came just one week before a second planned vote of no confidence by the Harvard Faculty of Arts and Sciences. Former president Derek Bok served as interim president. Members of Harvard's Faculty of Arts and Sciences, which instructs graduate students in GSAS and undergraduates in Harvard College, had passed an earlier motion of "lack of confidence" in Summers' leadership on March 15, 2005 by a 218-185 vote, with 18 abstentions. The 2005 motion was precipitated by comments about the causes of gender demographics in academia made at a closed academic conference and leaked to the press.[34] In response, Summers convened two committees to study this issue: the Task Force on Women Faculty and the Task Force on Women in Science and Engineering. Summers had also pledged $50 million to support their recommendations and other proposed reforms. Drew Gilpin Faust is the 28th president of Harvard. An American historian, former dean of the Radcliffe Institute for Advanced Study, and Lincoln Professor of History at Harvard University, Faust is the first female president in the university's history.

Harvard was founded in 1636 by vote of the Great and General Court of the Massachusetts Bay Colony, making it the oldest institution of higher learning in the United States. Initially called "New College" or "the college at New Towne", the institution was renamed Harvard College on March 13, 1639. It was named after John Harvard, a young English clergyman from Southwark, London, an alumnus of the University of Cambridge (after which Cambridge, Massachusetts is named), who bequeathed the College his library of four hundred books and £779 pounds sterling, which was half of his estate. The charter creating the corporation of Harvard College came in 1650. In the early years, the College trained many Puritan ministers.The college offered a classic academic course based on the English university model—many leaders in the colony had attended Cambridge University—but one consistent with the prevailing Puritan philosophy. The College was never affiliated with any particular denomination, but many of its earliest graduates went on to become clergymen in Congregational and Unitarian churches throughout New England.[18] An early brochure, published in 1643, justified the College's existence: "To advance Learning and perpetuate it to Posterity; dreading to leave an illiterate Ministery to the Churche".

Religion and philosophy

The takeover of Harvard by the Unitarians in 1805 resulted in the secularization of the American college. By 1850 Harvard was the "Unitarian Vatican." The "liberals" (Unitarians) allied themselves with high Federalists and began to create a set of private societies and institutions meant to shore up their cultural and political authority, a movement that prefigured the emergence of the Boston Brahmin class. On the other hand, the theological conservatives used print media to argue for the maintenance of open debate and democratic governance through a diverse public sphere, seeing the liberals' movement as an attempt to create a cultural oligarchy in opposition to Congregationalist tradition and republican political principles.

In 1846, the natural history lectures of Louis Agassiz were acclaimed both in New York and on the campus at Harvard College. Agassiz's approach was distinctly idealist and posited Americans' 'participation in the Divine Nature' and the possibility of understanding 'intellectual existences.' Agassiz's perspective on science combined observation with intuition and the assumption that one can grasp the 'divine plan' in all phenomena. When it came to explaining life-forms, Agassiz resorted to matters of shape based on a presumed archetype for his evidence. This dual view of knowledge was in concert with the teachings of Common Sense Realism derived from Scottish philosophers Thomas Reid and Dugald Stewart, whose works were part of the Harvard curriculum at the time. The popularity of Agassiz's efforts to 'soar with Plato' probably also derived from other writings to which Harvard students were exposed, including Platonic treatises by Ralph Cudworth, John Norris, and, in a Romantic vein, Samuel Coleridge. The library records at Harvard reveal that the writings of Plato and his early modern and Romantic followers were almost as regularly read during the 19th century as those of the 'official philosophy' of the more empirical and more deistic Scottish school.

Charles W. Eliot, president 1869-1909, eliminated the favored position of Christianity from the curriculum while opening it to student self-direction. While Eliot was the most crucial figure in the secularization of American higher education, he was motivated not by a desire to secularize education, but by Transcendentalist Unitarian convictions. Derived from William Ellery Channing and Ralph Waldo Emerson, these convictions were focused on the dignity and worth of human nature, the right and ability of each person to perceive truth, and the indwelling God in each person

Harvard University is a private Ivy League university located in Cambridge, Massachusetts, established in 1636 by the Massachusetts legislature. Harvard is the oldest institution of higher learning in the United States and the first corporation (officially The President and Fellows of Harvard College) chartered in the country.

Harvard was named after its first benefactor, John Harvard. Although it was never formally affiliated with a church, the college primarily trained Congregationalist and Unitarian clergy. Harvard's curriculum and students became increasingly secular throughout the eighteenth century and by the nineteenth century had emerged as the central cultural establishment among Boston elites. Following the American Civil War, President Charles W. Eliot's forty year tenure (1869–1909) transformed the college and affiliated professional schools into a centralized research university and Harvard became a founding member of the Association of American Universities in 1900.[9] James Bryant Conant led the university through the Great Depression and World War II and began to reform the curriculum and liberalize admissions after the war. The undergraduate college became coeducational after its 1977 merger with Radcliffe College. Drew Gilpin Faust was elected the 28th president in 2007 and is the first woman to lead the university. Harvard has the largest financial endowment of any school in the world, standing at $25.6 billion as of September 2009.[3] Harvard's history, influence, and wealth have made it one of the most prestigious universities in the world.

The university comprises ten separate academic units with campuses throughout the Boston metropolitan area.Harvard's 210-acre (85 ha) main campus is centered on Harvard Yard in Cambridge, approximately 3.4 miles (5.5 km) northwest of downtown Boston. The business school and athletics facilities, including Harvard Stadium, are located across the Charles River in Allston and the medical, dental, and public health schools are located in the Longwood Medical Area.

As of 2010, Harvard employs about 2,100 faculty to teach and advise, approximately 6,700 undergraduates (Harvard College) and 14,500 graduate and professional students.[13] Eight U.S. Presidents have graduated from Harvard and 75 Nobel Laureates have been affiliated with the university as students, faculty, or staff. Harvard is also the alma mater of sixty-two living billionaires, the most in the country.[14] The Harvard University Library is the largest academic library in the United States, and the third largest library in the country.[15]

The Harvard Crimson competes in 41 intercollegiate sports in the NCAA Division I Ivy League. Harvard has an intense athletic rivalry with Yale University traditionally culminating in The Game, although the Harvard-Yale Regatta predates the football game.
