Michael Peter Drazin(born 5 June 1929) is a British and American mathematician, working innoncommutative algebra.

Background

The Drazins (Дразин) were aRussian Jewishfamily who moved to the United Kingdom in the years beforeWorld War I.Isaac Drazin founded in 1927 a well-known electrical goods shop inHeath Street,Hampstead,which existed for over 50 years.^[1]

Isaac Drazin married Leah Wexler, and had three sons, of whom Michael was the eldest, andPhilip Drazin,also a mathematician, was the youngest, the middle son being David; and died 1 January 1993.^[2]^[3]

Life

Michael Drazin was born in London on 5 June 1929.^[4]His younger brother Philip was educated as a boarder atSt Christopher School,LetchworthduringWorld War II.^[5]The self-published memoirs of Roger Atkinson, a school friend of Michael (Mike), indicate that Drazin attendedKing Alfred School, London,located inHampstead,retaining contacts at the school when it was evacuated in wartime toRoyston, Hertfordshire;Atkinson was a boarder at St Christopher School, Letchworth from September 1942. In 1946 Atkinson and Drazin visited Paris together.^[6]

Drazin was a student at theUniversity of Cambridge,graduating B.A. in 1950 and M.A. in 1953.^[4]He was awarded a Ph.D. in 1953 for a dissertationContributions to Abstract Algebrawritten with advisersRobert RankinandDavid Rees.^[7]He was a Fellow ofTrinity College, Cambridgefrom 1952 to 1956, during that period relocating to the United States.^[8]

In the academic year 1957–8 Drazin was Visiting Lecturer atNorthwestern University.^[9]In 1958 he began a period at RIAS Inc. (theResearch Institute for Advanced Studies) inBaltimoreas senior scientist, after which he took a position as associate professor atPurdue Universityin 1962.^[8]^[10]^[11]

Works

Drazin gave his name to a type ofgeneralized inverseinring theoryandsemigroup theoryhe introduced in 1958, now known as theDrazin inverse.It was later extended to contexts inoperator theory.^[12]

While at RIAS, Drazin worked withEmilie Virginia Haynsworth,then at theNational Bureau of Standards,within itsnumerical analysisprogram.^[13]He also worked with the metallurgist Henry Martin Otte of RIAS, and they published a book of crystallographic tables.^[14]^[15]
