Question: Who founded the company that created the Leica M6 camera?
Context: Leica Camera AG is a German company that manufactures optics and high end cameras.  The company was founded by Ernst Leitz in 1924.  The name Leica is derived from the first three letters of his surname (Leitz) and the first two of the word camera: lei-ca. MegaVision is an American company that manufactures high-end digital photographic equipment.  It was founded in 1983 to create a state-of-the-art image processing computer.  MegaVision was the first company to produce a digital camera back for sale, using a 4 megapixel vidicon tube behind a Cambo technical view camera.  MegaVision has always produced the capture software that controls their camera hardware.  MegaVision produced the first live focus video in a digital still camera porting video over twisted pair wires (1993).  MegaVision produced the first gamut alarm light metering with their Color Coded Light Metering (1993).  MegaVision produced the first RAW file removable media digital camera with the Batpac digitizer and the S2/S3 series camera backs (1996).  MegaVision produced the first computer mounted digital camera back using the E3/E4/E5 and the OQO computers (2005).  MegaVision currently produces a 10 band visible plus 365 nm UV and 5 band IR EurekaVision lighting system for their 50 megapixel Monochorme E7 camera back. The Leica Freedom Train was a rescue effort in which hundreds of Jews were smuggled out of Nazi Germany before the Holocaust by Ernst Leitz II of the Leica Camera company, and his daughter Elsie Kuehn-Leitz. The Wild (Heerbrugg) company was founded in 1921 in Switzerland.  The company manufactured optical instruments, such as surveying instruments, microscopes and instruments for photogrammetry among others.  The company changed its name several times, first being known as "Heinrich Wild, Werkstätte für Feinmechanik und Optik", then "Verkaufs-Aktiengesellschaft Heinrich Wild's Geodätische Instrumente", later "Wild Heerbrugg AG", later "Wild-Leitz".  The company was linked with Leica in 1989, then it became part of Leica Holding B.V. Its subsidiary Leica Geosystems AG became part of the Swedish Hexagon AB Group of companies in 2005. Arricam is a 35 mm movie camera line manufactured by Arri.  It is Arri's flagship sync-sound camera line, replacing the Arriflex 535 line.  The design was developed by Fritz Gabriel Bauer and Walter Trauninger, and is heavily derivative of the cameras Bauer created for his Moviecam company, which was bought out by Arri in the mid-1990s.  As such, the Arricam is a fusion of the mechanical and intuitive design innovations of the Moviecam and the interchangeable accessories and complex electronic integration of the Arriflex.  s of 2006 , the Arricam is considered, along with the Panaflex Millennium line, the top sync-sound camera system currently in usage, and is extremely popular amongst bigger budget feature films.  The line comprises two camera body models, the ST (Studio) and LT (Lite).  The Arricam ST is intended as a full-capability camera, including two camera magazine mounting configurations, whereas the Arricam LT is optimized for smaller, lightweight usage in handheld and Steadicam application, with only the option to mount the magazine in the rear position.  Both cameras use motorized displacement magazines, have electronic rotating mirror shutters mounted beneath the film gate (as opposed to beside it, as in Panavision cameras), and contain independently adjustable sprocket pulleys within the camera body. This is a list of Leica cameras.  Leica Camera AG is a German optics company which produces Leica cameras.  The predecessor of the company, formerly known as Ernst Leitz GmbH, is now three companies: Leica Camera AG, Leica Geosystems AG, and Leica Microsystems AG, producing cameras, geosurvey equipment, and microscopes, respectively.  The Leica cameras are grouped by camera model and year of release. The Leica M6 is a rangefinder camera manufactured by Leica from 1984 to 1998. The Leica M7 is a 35 mm rangefinder camera introduced by Leica AG in 2002 as a direct successor to the M6.  The electronic Leica M7 is a departure from previous mechanical designs for the M series. The Nicca Camera Co. Ltd. started as the optical workshop Kōgaku Seiki Co. in 1940, founded by former employees of Canon.  Its first camera, the Nippon, a close copy of the Leica rangefinder camera, was produced in 1942. The Leica SL (Typ 601) is a full frame 35mm format mirrorless system camera announced by Leica Camera AG on October 20, 2015.  The SL is promoted as a camera system for professional applications.  Beside the Leica S-System, the Leica SL-System is the 2nd professional camera system in the company's product portfolio.
