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. They made the Rulex and Perfekt shutters and they also made cameras and lenses. Their logo was NH inside a circle.

There is sporadic reference to the following models:

• Condor (4.5x6 folding according to McKeown)
• Prince ?
• Princeflex, the first Japanese TLR
