This publication rewrites the history of modern architecture to elevate the female architects who helped build the movement. Starting with a theoretical analysis that situates women’s roles both in society and architecture specifically, the author examines the transition from women as objects to subjects at the advent of modernity. This theoretical basis is grounded through four case studies on pioneering women architects: Eileen Gray (Ireland, 1878–1976), Lily Reich (Germany, 1885-1947), Margarete Schütte-Lihotzky (Austria, 1897-2000), and Charlotte Perriand (France, 1903–1999). Originally written in Spanish. Table of Contents: Part I: Women and Society 1. Woman and Architecture 2. Woman and Social Evolution 3.
