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.
There is a probable relationship with Fujimoto, maker of the Prince 4.5x6 folding. Some sources say the Princeflex was made by Fujimoto, but on the rare Princeflex pictures there are Neumann & Heilemann markings.
