University that laid the groundwork for its transformation into one of the leading medical schools in the world. In 1906, the medical school moved to its current location in the Longwood Medical and Academic Area. The Longwood campus's five original marble-faced buildings of the quadrangle still remain in use today. Innovations Harvard Medical School postdoctoral trainees and faculty have been associated with a number of important medical and public health innovations: Broadening admissions Women In mid-1847, Professor Walter Channing's proposal that women be admitted to lectures and examinations was rejected by the President and Fellows of Harvard College. While Harriot Kezia Hunt was soon after given permission to attend medical lectures, this permission was withdrawn in 1850. In 1866, two women with extensive medical education elsewhere applied but were denied admission. In 1867, a single faculty member's vote blocked the admission of Susan Dimock. In 1872, Harvard declined a gift of $10,000 conditioned on medical school admitting women medical students on the same term as men. A similar offer of $50,000, by a group of ten women including Marie Elizabeth Zakrzewska, was declined in 1882; a committee of five was appointed to study the matter. After the medical school moved from North Grove Street to Boylston Street in 1883, professor Henry Ingersoll Bowditch's proposal that the North Grove Street premises be used for medical education for women was rejected. In 1943, a dean's committee recommended the admission of women, the proportion of men and women being dependent solely on the qualifications of the applicants. In 1945, the first class of women was admitted; projected benefits included helping male students learn to view women as equals, increasing the number of physicians in lower-paid specialties typically shunned by men, and replacing the weakest third of all-male classes with better-qualified women. By 1972, about one-fifth of Harvard medical students were women. African Americans In 1850, three black men, Martin Delany, Daniel Laing Jr., and Isaac H. Snowden, were admitted to the school but were later expelled under pressure from faculty and other students. In 1968, in response to a petition signed by hundreds of medical students, the faculty established a commission on relations with the black community in Boston; at the time less than one percent of Harvard medical students were black. By 1973, the number of black students admitted had tripled, and by the next year, it had quadrupled. In 2011, HMS
