aviation pioneer Glenn L. Martin organized a company around a modest
airplane construction business and built it into a major airframe supplier to
U.S. military and commercial customers. Martin Marietta was established
in 1961 when the Glenn L. Martin Company merged with American-Marietta
Corp., a leading supplier of building and road construction materials.
Lockheed Martin Corporation was formed in March 1995 with the merger of
and Martin Marietta Corporation.
