Sloan and National Science Foundation research fellowships. Frisch served on the Physics Advisory Committee of the National Science Foundation, on the Brookhaven High Energy Advisory Committee, and was chairman of the Long-Range Planning committee of the Fermi National Accelerator Laboratory. Frisch was active in the field of  nuclear disarmament, participating in the Moscow Pugwash Conference in 1960, editing the book "Arms Reduction" in 1961, and participating in the 1962 Woods Hole Summer Study on Inspection. Among his scientific publications was a 1963 paper in which he and James H. Smith succeeded in showing objective time dilation in the decay of cosmic muons. A thirty-five-minute movie describing this experiment performed both on the top of Mount Washington in New Hampshire as well as at MIT is available online. He was married to biologist Rose Frisch.
