El segundo sexo
Some important events laid the groundwork for the second wave. French writer Simone de Beauvoir had in the 1940s examined the notion of women being perceived as "other" in the patriarchal society. She went on to conclude in her 1949 treatise "The Second Sex" that male-centered ideology was being accepted as a norm and enforced by the ongoing development of myths, and that the fact that women are capable of getting pregnant, lactating, and menstruating is in no way a valid cause or explanation to place them as the "second sex". This book was translated from French to English (with some of its text excised) and published in America in 1953.
