Dan Hill has linked to some interviews with architects at the BBC. Some of them are quite interesting, including Walter Gropius and Mies van der Rohe talking about the creation of the Bauhaus and open plan architecture.
This Gropius clip about human beings as the starting point of design is probably the best one, much more "user-centered" than later modernism would make you suspect. I only wish the clips were a little longer.   09/03/03
