Neumann & Heilemann was a company founded in the 1930s by Willy Neumann and Mr. Heilemann, two German people living in Japan.
Willy Neumann had previously worked for Krauss in Paris, and Mr. Heilemann for Kenngott, then they helped Kazuo Tashima to found the Nichidoku company, later Molta (predecessor of Minolta). Heilemann left Molta in November 1931, followed by Neumann in 1932, who took some employees with him. They founded 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), using NH inside a circle as their logo. It was installed in a new plant in Takagi (高木), currently Ōmori-chō (大森町) in the city of Nishinomiya (西宮市), near the Mukogawa (武庫川) river.
The company made the Neuheil, Rulex, Perfect and Perfekt shutters. It also made Radionar and other lenses, certainly assembling imported Schneider elements in a locally-produced barrel. The company also became involved in the production of machine tools, under the influence of Willy Neumann, and they made an experimental motor tricycle.
One of the company's last products was the Prince Flex camera (first Japanese TLR), first advertised in August 1937 by the distributor Fukada Shōkai. It is said that the body casting was bought from a sub-contractor, and that the final assembly took place in the Takagi plant.
Willy Neumann founded the separate company Neumann Seiki (ノイマン精機) in August 1937, to manufacture machine tools in a new plant in the nearby city of Ashiya (芦屋市), and the company Neumann & Heilemann was dissolved on 11 September 1937. All the assets and trademarks were sold to Fujimoto Shashinki Seisakusho, and the Takagi plant became Fujimoto's Mukogawa plant, reportedly called Mukogawa Shashin Kōgyō (武庫川写真工業, meaning Mukogawa Photo Industries). (The Semi Lucky by Fujimoto would be produced in this plant.) Fujimoto continued the production of the Prince Flex camera and Rulex and Perfekt shutters, and the assembly of the Radionar lenses. The NH logo and "Neumann & Heilemann" markings were kept on all these products, and it is not possible to identify for sure those which were made after Fujimoto's takeover. The Mukogawa plant was finally handed over to Chiyoda Kōgaku Seikō (predecessor of Minolta)
Neumann died in a motorbike accident in either 1938 or 1939. Heilemann was suspected of spying during the war, and was imprisoned for some months in 1943. After the war, he built a small plant in Kōyōen (甲陽園), in the city of Nishinomiya (西宮市), and made various products, including a camera shutter called Heilemann, which met little success.
Shutters by Neumann & Heilemann:
A Neuman shutter (single "n"), giving B, 1–250 speeds and inscribed NEUMAN OPTICAL WORKS, is known on the postwar Royal Senior but is probably not related to the Neumann & Heilemann company.
All these lenses were certainly assembled from imported elements, probably supplied by Schneider for the Radionar.
