Written in an engaging and accessible style, this first broadly focused compensatory history of technology not only includes women’s contributions but begins the long-overdue task of redefining technology and significant technology and to value these contributions correctly. Stanley traces women’s inventions in five vital areas of technology worldwide–agriculture, medicine, reproduction, machines, and computers–from prehistory (or origin) forward, profiling hundreds of women, both famous and obscure. The author does not ignore theory. She contributes a paradigm for male takeovers of technologies originated by women.
