In this important study, former United States primary patent examiner Patricia Carter Sluby pays homage to the inventive spirit of African Americans. Beginning with the contributions of enslaved Africans brought to American shores, Sluby introduces inventors and patent holders from all fields up to and including the leading edge of today's technology. Along with such recognizable figures as George Washington Carver and Madam C. J. Walker, readers will discover little-known or forgotten pioneers of devices such as a tobacco substitute, a home security system, and a portable heart monitor. Particular attention is given to the innovations of women inventors and scientists.
