In 1949 she enrolled at the historically black Howard University, seeking the company of fellow black intellectuals. The school is in Washington, D.C., where she encountered racially segregated restaurants and buses for the first time. She graduated in 1953 with a B.A. in English and went on to earn a Master of Arts from Cornell University in 1955. Her Master's thesis was Virginia Woolf's and William Faulkner's Treatment of the Alienated. She taught English, first at Texas Southern University in Houston for two years, then at Howard for seven years. While teaching at Howard, she met Harold Morrison, a Jamaican architect, whom she married in 1958. She was pregnant with their second son when she and Harold divorced in 1964. After the breakup of her marriage, she began working as an editor in 1965 for L. W. Singer, a textbook division of Random House, in Syracuse, New York. Two years later she transferred to Random House in New York City, where she became their first black woman senior editor in the fiction department. In that capacity, Morrison played a vital role in bringing black literature into the mainstream. One of the first books she worked on was the groundbreaking Contemporary African Literature (1972), a collection that included work by Nigerian writers Wole Soyinka and Chinua Achebe and South African playwright Athol Fugard. She fostered a new generation of African-American authors, including Toni Cade Bambara, Angela Davis, and Gayl Jones, whose writing Morrison discovered, and she brought out the autobiography of boxer Muhammad Ali, The Greatest. She also published and publicized the work of Henry Dumas, a little-known novelist and poet who was shot to death by a transit officer in the New York City subway in 1968. Among other books Morrison developed and edited is The Black Book (1974), an anthology of photographs, illustrations, essays, and other documents of black life in the United States from the time of slavery to the 1970s. Random House had been uncertain about the project, but it got good reviews. Alvin Beam reviewed it for the Cleveland Plain Dealer, writing, "Editors, like novelists, have brain children--books they think up and bring to life without putting their own names on the title page. Mrs. Morrison has one of these in the stores now, and magazines and newsletters in the publishing trade are ecstatic, saying it will go like hotcakes."
