Problem in a Cover Story

The capsule biography of Dr. Fred Bell (seen via Orac) includes the lines:

While working University of Michigan Dr. Bell had the priviledge of working under the mentorship of Dr. Katz. Dr. Katz came over here, as an honored scientist, previously working for the 3rd Reich under Adolph Hitler. Wernher von Braun and Dr. Katz both were transferred here by the American government under an operation known as Operation Paperclip.

Saaaay what? Isn't Katz a Jewish name? Would a Jew work for the 3rd Reich?
