Richard M. Friedberg

Friedberg is also known for his love of music and poetry. He wrote poems in several letters to cognitive scientist and writer Douglas Hofstadter in 1989. The last letter contains two sonnets ”The Electromagnetic Spectrum” and "Fermions and Bosons". These letters also include critiques and analyses of topics in Metamagical Themas, a collection of articles that Hofstadter wrote for Scientific American during the early 1980s.

In 1968, Friedberg proved independently what became known as Bell’s inequality, not knowing that J. S. Bell had proved it a few years earlier. He showed it to the physicist and historian Max Jammer, who somehow managed to insert it into his book “The Conceptual Development of Quantum Mechanics”, although the latter bears the publication date 1966. This caused Friedberg some embarrassment later when classmates at Harvard, knowing of the result only through Jammer’s book, supposed that Friedberg was the first discoverer. (A letter from Friedberg to Jammer dated May 1971 begins, “It was nice of you to remember what I showed you in 1968. I finally got around to writing it up in 1969, but just then I found out about Bell’s 1964 paper (Physics 1, 195) which had anticipated my ‘discovery’ by three years. So I did not publish.”) More recently, Friedberg worked on the foundations of quantum mechanics in collaboration with the late Pierre Hohenberg.

Friedberg's most well-known work dates back to the mid-1950s. As an undergraduate at Harvard, he published several papers over a period of 2–3 years. The first paper introduced the priority method, a common technique in computability theory, in order to prove the existence of recursively enumerable sets with incomparable degrees of unsolvability.

Richard M. Friedberg (born October 8, 1935), is a theoretical physicist who has contributed to a wide variety of problems in mathematics and physics. These include mathematical logic, number theory, solid state physics, general relativity, particle physics, quantum optics, genome research, and the foundations of quantum physics.

Friedberg was born in Manhattan on Oct 8, 1935, the child of cardiologist Charles K. Friedberg, and playwright Gertrude Tonkonogy.
