Neumann & Heilemann

Neumann & Heilemann was a company founded in the 1930s by Billy Neumann and Willy Heilemann, two Germans living in Japan. Billy Neumann had previously worked for Krauss in Paris, and Willy Heilemann for Kenngott, then they had helped Kazuo Tashima to found the Nichi-Doku company that would become Minolta, before founding their own company. Neumann & Heilemann made the Rulex and Perfekt shutters and they also made cameras and lenses. Their logo was NH inside a circle.

Cameras

• Condor? (4.5x6 folding according to McKeown)

Note: a, obviously a Baldax copy, Condor folder has been observed at a Yahoo Japan auction, with an Olympus Koho 1-200-B-T shutter, a Deller Anastigmat 7.5cm f/3.5 lens and a case marked Semi Condor.

• Prince Flex, the first Japanese TLR

Both Neumann & Heilemann and Fujimoto used the name Prince on some cameras, but they also shared the same distributor Fukada Shōkai, and maybe the name was owned by this distributor. This is discussed in the Prince page.
