Neumann & Heilemann was a company founded in the 1930s by Billy Neumann and Willy Heilemann, two German people living in Japan.

History

Billy Neumann had previously worked for Krauss in Paris, and Willy Heilemann for Kenngott, then they had helped Kazuo Tashima to found the Nichidoku company, later Molta (predecessor of Minolta).[1] Heilemann left Molta in November 1931, followed by Neumann in 1932, to found their own company, called Neumann & Heilemann Feinmechanisch Werkstätten Gōshi-gaisha (ノイマン・ハイレマン・ファインメハニシェ・ウエルクステッテン合資会社), whose logo was NH inside a circle..[2]

The company made the Neuheil, Rulex and Perfect or Perfekt shutters as well as lenses and maybe cameras.

Cameras

The company certainly participated in the development of the Prince Flex, the first Japanese TLR (1937), distributed by Fukada Shōkai. It sold a plant in Mukogawa to Fujimoto in 1937,[3] and the Prince Flex was perhaps taken over by Fujimoto at the same time (see Prince Flex). (The Semi Lucky by Fujimoto would be produced in this Mukogawa plant.)[4]

The attribution of the Condor folders to Neumann & Heilemann is a mistake.[5]

Shutters

Lenses

  • Radionar 7.5cm f/4.5, certainly assembled from elements supplied by Schneider[6]
  • Tritar 10.5cm f/4.5[7]

  5. Mistake in McKeown, p.717. Most Condor folders have a Rulex shutter made by the company.
  6. Tanimura, p.50 of Kurashikku Kamera Senka no.11, says that Schneider lenses were imported as separate elements and were assembled in Japan.
