Live and act

Cohn was born to Jewish parents in Hamburg, his father James Cohn was a foreign trade merchant, his mother Julia Cohn a teacher. Both parents perished in the Holocaust (they were deported to Riga in 1941), Cohn himself was sent to Great Britain as a youth in 1939 on a children's transport . During the war he was trained as a mechanic and worked as a fitter on a workbench.

Cohn studied at Cambridge University , where he made his bachelor's degree in 1948 and received his doctorate in 1951 with Philip Hall . He then spent a year at Nancy University and a ten-year lecturer at Manchester University . In 1961/62 he was visiting professor at Yale University and in 1962 at the University of California, Berkeley, and then became a reader at Queen Mary College . In 1964 he was visiting professor at the University of Chicago and in 1964 at the State University of New York at Stony Brook . In the same year he became professor at Bedford College, University of London and chairman of its mathematics faculty. After closing due to budget cuts, he moved to University College London in 1984 , where he became an Astor Professor of Mathematics in 1986. In 1989 he became professor emeritus there. He was visiting professor at universities in Canada, Israel, France, India, the USA and also in Germany (Bielefeld).

Cohn was considered a leading algebraist, with work specifically on non-commutative ring theory. He wrote several textbooks on algebra.

In 1972 he received the Lester Randolph Ford Award of the Mathematical Association of America (for Rings of fractions , American Math. Monthly, Vol. 78, 1971, pp. 596-615) and in 1974 the Senior Berwick Prize of the London Mathematical Society , whose president he was from 1982 to 1984. Before that, he was their secretary from 1965 to 1967 and on their council from 1968 to 1975 and 1979 to 1984 and also edited their series of monographs for many years. In 1980 he became a Fellow of the Royal Society . In 1970 he was invited speaker at the International Congress of Mathematicians in Nice ( Free ideal rings and free products of rings ).

He had been married since 1958 and had two daughters.
