After the Civil War, Harvard Medical School (HMS) began to accept Black students, although in small numbers (often no more than one Black student per matriculating class).
The first scholarship supporting Black students at HMS was established in 1893 when Harriet Hayden, the wife of Lewis Hayden, donated funds to establish a scholarship for "needy and worthy colored students in the Harvard Medical School," named The Lewis and Harriet Hayden Scholarship for Colored Students. Harriet and Lewis Hayden were members of Boston's Black community who had escaped slavery and arrived in Boston in 1846. Lewis Hayden, a noted abolitionist, ran a clothing store, and was elected to the Massachusetts House of Representatives in 1873. He died in 1889, and his wife, Harriet, bequeathed money to HMS to support educating students of color. The scholarship continues to be awarded to this day.
