Walter Gropius
Walter Gropius (May 18th 1883 - July 5th 1969) is the inventor of the Bauhaus. Born in Berlin, Walter Gropius was the third child of Walter Adolph Gropius and Manon Auguste Pauline Scharnweber. Gropius married Alma Mahler (1879-1964), widow of Gustav Mahler. Walter and Alma's daughter, named Manon after Walter's mother, was born in 1916. When Manon died of polio at age eighteen, composer Alban Berg wrote his Violin Concerto in memory of her (it is inscribed "to the memory of an angel"). Gropius and Alma divorced in 1920. (Alma had by that time established a relationship with Franz Werfel, whom she later married.) In 1923 Gropius married Ise (Ilse) Frank (d. 1983), and they remained together until his death. They adopted Beate Gropius, also known as Ati.
