Marcia M. Gallo received her doctoral degree with distinction from the City University of New York Graduate Center in 2004. She published her first book, the prizewinning Different Daughters: A History of the Daughters of Bilitis and the Rise of the Lesbian Rights Movements, in 2006 (Carroll & Graf); it was reissued in 2007 (Seal Press).

In 2015, Gallo published “No One Helped”: Kitty Genovese, New York City, and the Myth of Urban Apathy(Cornell University Press), which examines the story of Catherine “Kitty” Genovese, whose rape and murder in Queens, New York in 1964 became an international symbol of urban decay. Described as “incisive,” it explores the construction and promotion of an infamous true crime story within the context of the social movements of the times. “No One Helped” won both the 2015 Lambda Literary Award for LGBT Nonfiction and the 2015 Publishing Triangle Judy Grahn Award for Lesbian Nonfiction; it also was a finalist for the 2015 USA Best Book Awards (USA Book News) for Gay & Lesbian Nonfiction.

As Associate Professor of History at the University of Nevada, Las Vegas, Gallo teaches undergraduate and graduate courses on race, gender and sexuality as well as, oral history and public history. She serves as President of the Southwest Oral History Association for 2015-17.
