1944 – 1945 – He worked on the Manhattan Project but was dismissed due to his activities as a member of the Communist Political Association.
1949 – Went to Columbia University to work on a doctorate in optical and microwave spectroscopy.
1956 – Proposed using optical pumping to excite a maser, and discussed this idea with the maser’s inventor, Charles Townes (who was also a professor at Columbia). Townes gave Gould advice on how to obtain a patent on his innovation, and agreed to act as a witness.
1957 – He ealized that one could make an appropriate optical resonator by using two mirrors in the form of a Fabry-Pérot interferometer.
1967 – Left TRG and joined the Polytechnic Institute of Brooklyn, now the Polytechnic University of New York, as a professor.
1968 – His first laser patent was awarded, covering an obscure application—generating X-rays using a laser.
1973 – Left the Polytechnic Institute of Brooklyn to help found Optelecom, a company in Gaithersburg, Md. that makes fiberoptic communications equipment.
1991 – He was elected to the National Inventors Hall of Fame. Gould said in his acceptance speech: "I think it’s important to be self-critical.
