The Space Vehicle Pocket Designer was produced in 1959 by the Denver Division of the Martin Company. The Martin Company was founded in 1912. During WW2 it produced military aircraft. After the war it moved into aerospace.
In 1961 the Martin Company merged with the American-Marietta Corporation, a chemical products and construction materials manufacturer, to form the Martin Marietta Corporation. In 1995, Martin Marietta, then the nation’s 3rd-largest defence contractor, merged with the Lockheed Corporation, then the nation’s second largest defence contractor, to form the Lockheed Martin Corporation, the largest such company in the world.
The Pocket Designer consists of four items.
A 6.25″ x 5.125″ folder with inner pocket.
A six page brochure [Space Vehicle Designer, Instructions for use].
A 4.5″ diameter pocket ‘computer’ or circular slide rule. The rule is made of card.
Two Rocket Vehicle Design Aid graphs.
The graphs were intended for use by engineers, the ‘computer’ could also be used by laymen.
