The Kodak Super Six-20 is accepted as being the first camera with automatic exposure, introduced by Kodak in 1938.
Description[]
Exposure was controlled by a mechanical linkage from a selenium light meter to the aperture control. Pressing the shutter release first locked the meter needle, and moved a lever controlling the aperture up to the needle, before firing the shutter. Adjusting the speed control moved a cover over more or less of the photocell[1]. The film was advanced by a lever which also opened the red window cover and cocked the shutter, which "guards against double-exposures and blanks"[2].

The folding clam-shell design was by Joseph Mihalyi and styled by Walter Dorwin Teague. This incorporated crank winding and a coupled rangefinder[3].
The Super Six-20 was not a great success due to its enormously high price - $225 USD[4] (app. $3,200 USD in 2007), much more than a contemporary Leica - and a reputation for unreliability. Kodak employees had nicknamed it "the boomerang" for its regular returns for service[3].
It was withdrawn in 1944; production estimates vary between 714 and 725 being made; 719 is the most common guess.

Postscript[]
A auto-exposure patent pre-dates the release of this camera; US Patent 2,058,562 was granted in 1935 to Gustav Bucky and Albert Einstein! This covers a different, possibly impractical system using neutral-density filters to control light. The Super Six-20 remains the first auto-exposure camera to go on sale.
In spite of the commercial failure of the Super Six-20, the "trap-needle" (Electric-Eye, "EE") system of auto-exposure eventually became popular from the late 1950s, until it was replaced by electronic systems in the 1970s.
