Richard Timothy Daly, Jr. directed the development of the commercial clock. The papers probably include material created by him and other project personnel listed below.
The first commerical atomic clock was invented by a team of physicists working under J. R. Zacharias at MIT after WWII. They were produced by NATCO, Inc. of Malden, Mass., from 1955-1967. The company also researched other applications for the clocks, including a collision avoidance system.
Original acquisition: Blueprints, technical drawings, research reports, instruction manuals, photographs, marketing brochures documenting the production of the first commerical cesium beam frequency standard and subsequent models. Other projects and proposals, esp. Collision Avoidance system, are also documented.
