In 1929, the Great Lakes Aircraft Corporation was formed in Cleveland, Ohio, at the former site of the Martin Aircraft Company. They built civilian biplanes, float planes, as well as biplane torpedo bombers and dive bombers under contract to the US Navy. In 1933, the Company was reportedly working on a steam power plant for driving aircraft turbines.

The Great Lakes Trophy was awarded in 1930 and 1931 to the fastest plane with an engine of 510 cubic inches or less that participated in the National Air Tour.

Great Lakes Aircraft Corporation of Cleveland, Ohio produced a design for a small two-seat sports/trainer in early 1929, with the first prototype flying in March 1929.

The resulting aircraft, the 2T-1 was a single bay biplane of mixed, fabric-covered construction. Power was by a single 90 hp Cirrus III inline engine.
