Leica (1036)

Leica invented the 24x36mm film format, the 35mm rangefinder camera, the film enlarger for the darkroom (1920s), the flash shoe, the length of a roll film (with 36 pictures; this was how far Barnack could stretch his arms), auto focus lenses (in the 70s), the "reporter" film back (Leica 250 with 250 pictures in 1933), and more.
