George Zweig

In 2003, Zweig joined the quantitative hedge fund Renaissance Technologies, founded by the former Cold War code breaker James Simons. He left the firm in 2010. Once his four-year confidentiality agreement with Renaissance Technologies expired, the 78-year-old Zweig returned to Wall Street and co-founded a quantitative hedge fund, called Signition, with two younger partners. They began trading in 2015.

Zweig later turned to research on hearing and neurobiology, and studied the transduction of sound into nerve impulses in the cochlea of the human ear, and how the brain maps sound onto the spatial dimensions of the cerebral cortex. In 1975, while studying the ear, he introduced a version of the continuous wavelet transform, the cochlear transform.

Gell-Mann received the Nobel Prize for physics in 1969, for his overall contributions and discoveries concerning the classification of elementary particles and their interactions; at that time, quark theory had not become fully accepted, and was not specifically mentioned in the official citation of the prize. In 1977 Richard Feynman nominated both Zweig, and Gell-Mann again, for the Nobel prize, but the nomination failed.

Zweig was born in Moscow, Soviet Union. His father was a structural engineer. He graduated from the University of Michigan in 1959, with a bachelor's degree in mathematics, having taken numerous physics courses as electives. He earned a PhD degree in theoretical physics at the California Institute of Technology in 1964.

George Zweig (/zwaɪɡ/; born May 30, 1937) is a Russian-American physicist. He was trained as a particle physicist under Richard Feynman. He introduced, independently of Murray Gell-Mann, the quark model (although he named it "aces"). He later turned his attention to neurobiology. He has worked as a Research Scientist at Los Alamos National Laboratory and MIT, and in the financial services industry.
