Black women have been breaking down barriers and shattering stereotypes for generations, playing a powerful role in American history. In the Trailblazers series, Gabrielle David examines the lives and careers of over four hundred brilliant women from the eighteenth century to the present. Each volume provides biographical information, photographs, and a historical timeline written from the viewpoint of Black women, offering accessible reference resources.

This fourth volume of Trailblazers explores the complicated relationship that Hollywood has had with Black women actors; significant Black women in the fields of science, technology, engineering, and mathematics (STEM); and pioneering Black women journalists. David includes actors such as Hattie McDaniel, Fredi Washington, and Nina Mae McKinney who blazed the trail for women like Pam Grier, Halle Berry, and Viola Davis. "Hidden figures" in STEM are brought to light, such as biologist Jewel Plummer Cobb, mathematician Dorothy Vaughan, roboticist Ayanna Howard, and computer scientist Timnit Gebru. In addition, profiles of publishing pioneers like Ida B. Wells-Barnett, Mary Ann Shadd Cary, Josephine St. Pierre Ruffin, and Nancy Hicks Maynard show how they paved the way for Carole Simpson, Yamiche Alcindor, Nikole Hannah-Jones, and Jemele Hill.
