Martha Ackmann

Ackmann's second book, Curveball, tells the story of Toni Stone, the first woman to play baseball in the Negro leagues. When Henry Aaron moved from the Indianapolis Clowns to the major leagues, Toni Stone replaced him. A fierce second baseman, Stone played against Ernie Banks, Willie Mays, Buck O’Neil, and Jackie Robinson. Producer Samantha Barrie optioned Ackmann's book for the stage, playwright Lydia R. Diamond wrote Toni Stone, and Pam MacKinnon directed the Roundabout Theatre Company production. The play had its world premiere in 2019 at the Laura Pels Theatre in New York and received widespread acclaim. The New York Times called April Matthis's portrayal of Toni Stone "sensational" and named the play a Critic's Pick.

Ackmann was awarded a Guggenheim Fellowship in 2008. She was a fellow in nonfiction at the Radcliffe Institute for Advanced Study at Harvard University in 2008–2009.

Ackmann’s books focus on "women who’ve changed America," with special attention to recovering stories of women who have fallen between the cracks of history. Her first book, The Mercury 13, detailed the largely unknown story of thirteen American women pilots who were secretly tested to be astronauts in the early days of the US space program. The book was selected for college and university Common Read programs. In 2007, the University of Wisconsin–Oshkosh awarded the Mercury 13 women honorary degrees and commended Ackmann for embodying "the ideas of social justice and equity in the public sphere."

Ackmann has presented lectures in Europe and across the United States. Her talks include readings and lectures on women in space, sports equity, and American women writers. Presentations include talks at the Kennedy Space Center, Chicago's Adler Planetarium, the National Baseball Hall of Fame, the Roundabout Theatre, and New York's 92nd Street Y. Ackmann's media appearances include the Today show, CNN, CBS Evening News, NPR, and the BBC.

She was on the faculty in the Gender Studies department at Mount Holyoke College from 1986 - 2016. For nearly two decades, she taught a seminar on Emily Dickinson in the poet’s house in Amherst, Massachusetts. She is a past president of the Emily Dickinson International Society, co-founder of Legacy: A Journal of American Women Writers, and was featured in the 2017 Emily Dickinson documentary My Letter to the World.
