Poulenc Frères was a company in Paris, that made some cameras, before concentrating on production of chemicals. The company was based at 92 Rue Vielle du Temple, with another branch at 122 Boulevard Saint-Germain.
The company was founded as Whittmann & Poulenc in 1858 by Etienne Poulenc. The 'Frères' were his three nephews Gaston, Emile and Camille who inherited the company.

- Falling-plate Stand camera, about 1900 at Collection Appareils (the page shows a printed advertisement for the camera, which does not make clear the plate size).
- Detective Camera, about 1900, also at Collection Appareils. This wooden box-form camera has focusing by means of four auxiliary lenses selected by a lever on the front, and four aperture settings selected by another. It has a self-tensioning shutter with variabe speed (by varying the spring tension). The example shown at Collection Appareils is for 9×12 cm plates; McKeown also lists this camera, but for 8×11 cm plates.
The company was very successful in chemicals, becoming Rhone-Poulenc in 1928, which in turn became the Rhodia group in 1999.
