Samuel Calhoun Dominey Jr. was graduated with a bachelor of science degree in physics in 1952.

He served in the U.S. Army from 1952-54 and earned his U.S. Army commission in officer training school.

The engineer company he commanded built 39 bridges during the Korean War.

A Dodge native, he taught science in Galveston and Texas City schools. He did graduate work in nuclear physics at Southern Methodist University from 1954-58.

He then worked as a nuclear physicist in a number of capacities for General Dynamics, the Oak Ridge National Laboratory, Lockheed Aircraft, Westinghouse Corp. and Giannini Controls.

He is now president and chairman of General Nucleonics Inc., of Pomona, Calif., where he developed a helicopter main rotor blade crack detection system called the Inflight Blade Inspection System (IBIS).

He and his staff also have a number of patents using nuclear energy for peaceful purposes.

The IBIS system is used by the U.S. president's fleet of helicopters, all branches of the U.S. Armed Forces, as well as many foreign countries, and has saved a number of helicopters from crashing.
