Glenn L. Martin Company

After withdrawing from his association with the Wright-Martin Aircraft Corporation, American pioneer Glenn L. Martin founded in 1917 in Cleveland, Ohio, the Glenn L. Martin Company

The first great success of this firm was the MB-1 bomber, a large biplane required by the United States Army on January 17, 1918. The MB-1, of which ten serial copies were built, entered service too late for World War I, but its successor aircraft, the Martin MB-2, was so successful that the Army placed an order for 130 more.

In 1924, it manufactured the Curtiss SC-1 reconnaissance bomber under license. In 1929 Martin sold the Cleveland plant and built a new one in Maryland, near Baltimore.

In the 1930s Martin built flying boats for the US Navy, and the innovative B-10 bomber for the Army. He also built the famous Martin Model 130/156 China Clipper flying boats used by Pan Am airlines for their route between San Francisco and Manila.

During World War II, Martin's most important aircraft were the B-26 Marauder bomber and the PBM Mariner amphibian, widely used for maritime rescue, anti-submarine warfare, and transport.

Post-war efforts included ill-fated prototype bombers such as the XB-48 and XB-51, the B-57 Canberra night bomber, the P5M Marlin amphibian and the Martin 4-0-4 twin-engine passenger plane.

Martin merged with the American-Marietta Corporation in 1961 to become the Martin Marietta Corporation.

The Martin Company employed many engineers who later founded their own companies, including William E. Boeing, Donald Douglas, Lawrence Bell, and James S. McDonnell.
