Along with Frank Lloyd Wright, Mies van der Rohe, LeCorbusier, and Marcel Breuer, architect Walter Gropius was one of the most influential Modernist architects of the 20th century. Gropius founded the heralded Bauhaus in Dessau, Germany, but the rise of Hitler in the 1930's drove Gropius first to London working for Maxwell Fry, and later to Cambridge MA where he taught at Harvard and MIT. His post-war houses with Marcel Breuer were a distinctive combination of unusual geometries that people still treasure as owners and as fans. His granddaughter Erika Pfammatter is a musician, music teacher, and former minister of music. She's also the daughter of architect Charles Forberg and the stepdaughter of another famous architect, John Johansen. Later, a very special Gropius-related song by the one and only Tom Lehrer, still going strong at 92.
