HH,
OK, though von Braun perhaps did not care, it was his boss - Walter Dornberger who cared. And whose role in applied rocket science/industry is, IMHO, underestimated (only von Braun's name is in the air). In fact, Dornberger was, using modern terminology, the project manager. He hired young and talented Werner in 1932 who then became his tech. lead for V-2/A4.
