A scholar and author who helped make the study of women and their lives a legitimate subject for historians. In the mid-1960s, armed with a doctorate in history from Columbia University and a dissertation on two abolitionist sisters from South Carolina, Ms. Lerner entered an academic world in which women’s history scarcely existed. That picture changed rapidly, in large part because of her efforts while teaching at Sarah Lawrence College in the early 1970s. In creating a graduate program there, Ms. Lerner set about trying to establish women’s history as an academic discipline and to raising the status of women in the historical profession. Gerda Hedwig Kronstein was born on April 30, 1920, in Vienna, where her father, Robert, owned a large pharmacy. Her mother, the former Ilona Neumann, a free-spirited Bohemian at heart, tried unsuccessfully to reconcile her budding career as an artist with her duties as a housewife and mother. This struggle made a marked impression on her daughter. Immediately after Germany annexed Austria in 1938, Ms. Lerner’s father, a Jew, was tipped off that he was about to be arrested. As a hedge, he had started a pharmacy in Lichtenstein, and there he fled, whereupon the Gestapo arrested his wife and daughter to force his return. Five weeks later, after he sold his Austrian assets for a nominal sum, his wife and daughter were released and left for Lichtenstein as well. In 1941 she married Carl Lerner, a theater director and Communist. The couple moved to Hollywood, where Mr. Lerner became an apprentice film editor. Because of his politics, Mr. Lerner found it increasingly hard to find work in Hollywood, so in 1949 the couple returned to New York, where he became a top film editor, working on “Twelve Angry Men,” “Requiem for a Heavyweight” “Klute” and other films. In 1964, the two collaborated on the film “Black Like Me,” based on the 1961 book by the Southern white journalist John Howard Griffin that recounted his experiences disguised as a black man in the Deep South. Mr. Lerner directed and together they helped adapt the book for film. Mr. Lerner died in 1973 after a long illness. After earning her bachelor’s degree from the New School in 1963, Ms. Lerner enrolled at Columbia. Bending the rules, the university allowed her to complete her master’s and doctorate in three years. At Sarah Lawrence, where she began teaching history in 1968, she was the driving force behind what is widely credited as the first graduate program in women’s history in the United States, established in 1972. In 1980 she joined the history department at Wisconsin-Madison, where she created the university’s doctoral program in women’s history. She retired from Wisconsin in 1991.
