Mammen is one of the most versatile and unusual artists of her time. She was born Gertrud Johanna Mammen on November 21, 1890 in Berlin, Germany. During the 1920s and 1930s, Mammen created vivid depictions of life in the booming metropolis of Berlin. She portrayed people of all walks of life, but her focus was on the "New Woman" in the Weimar Republic and her role in society. At the time, Berlin was the center for lesbian and gay subculture in Germany. Mammen painted a realistic picture of her female subjects, unabashedly depicting lesbians involved in intimate relationships--some portraits less obvious and more covert than others. This article offers a look at the life and works of Mammen. (Contains 1 note.)
