Actually, color negative was "liberated" from Germany at the end of WWII, prior to that Kodachrome had come along in 1935. When I worked with Ansel in Yosemite I can assure you that he was very interested in working with color, and had tried to do the same sorts of things with it that he had perfected with B&W--Except the eye would not accept the "manipulated" print thus produced. With B&W he would commonly spend an hour--often more printing a single print.

Not quite correct. Kodachrome was first and Agfacolor followed but this was before WW II. During WW II, Agfa and Kodak continued development imdependently, Kodak did not get its technology from Agfa.
