Throwing contemporary listeners into historical re-enactments, radio encouraged identification with women of the past while simultaneously rejecting the idea that women’s capabilities were biologically-defined and thus continuous across time. Between 1936 and 1939, the Philadelphia Club of Advertising Women produced local radio plays dramatizing diverse subjects, from the legendary Molly Pitcher to Godey’s Lady’s Book editor Sarah Hale, as precedents for contemporary businesswomen’s participation in public activities. Meanwhile, historian Mary Ritter Beard, journalist Eva vom Baur Hansl, and scriptwriter Jane Ashman collaborated with the Office of Education, Federal Security Agency, Works Progress Administration, and NBC’s Women’s Activities Division on Women in the Making of America and Gallant American Women. Broadcast in 1939 and 1940, these programs publicized Beard’s World Center for Women’s Archives in New York and dramatized women’s diverse contributions as “co-makers” of history in politics, law, education, science, the press, and business. Melding feminist activism with corporate and network goals, radio’s revisionist histories urged wide audiences to reconceptualize the past.
