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: 4.5×6 folding according to McKeown, but the same also lists a New Semi Condor 4.5×6 vertical folding camera at the Nissan Kogaku entry

Note: At a Yahoo Japan auction, a 4.5x6 folder with the name Condor embossed in the leather has been observed with a Koho 1-200-B-T shutter, a Delter (or Deller or Deltar?) Anastigmat 7.5cm f/3.5 lens and a case marked Semi Condor. It was obviously a copy of the Balda Baldax, certainly the smaller version for #00 shutter size, because the Koho shutter (#0 size) seemed oversized. It had what looks like a complicated linkage to a body release.

• 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.
