Donald Levine | G.I. Joe creator, 86
Mr. Levine shepherded the toy through design and development as Hasbro's head of research and development. He and his team came up with an 111/2-inch articulated figure with 21 moving parts, and since the company's employees included many military veterans, it was decided to outfit the toy in the uniforms of the Army, Navy, Marines, and Air Force, with such accessories as guns, helmets, and vehicles.
Mr. Levine, who served in the Army in Korea, said he got the idea for the moveable figure as a way to honor veterans.
G.I. Joe hit the shelves in time for the 1964 Christmas shopping season and soon became a big seller at $4 apiece. It remained popular until the late 1960s, as opposition to Vietnam intensified and parents shied away from military-related toys. Hasbro countered in 1970 by introducing "Adventure Team" G.I. Joes that played down the military connection. Into the '70s, G.I. Joes featured "lifelike hair" and "kung-fu grip" and were outfitted with scuba gear to save the oceans and explorer's clothing for discovering mummies.
