He was born on March 5, 1910.

He had a Ph.D in chemistry. He worked for the National Bureau of Standards and the Labor and Public Welfare Committee. Earlier he had been a professor at the University of Alabama.[2]

He supplied documents to Whittaker Chambers and J. Peters for Soviet intelligence as early as 1936.[1] In his book, Witness, Whittaker Chambers refers to Pigman using the pseudonym "Abel Gross".[3] The Gorsky Memo cites him as "114th".

In 1954 he was at the Department of Biochemistry, of the New York Medical College.[4]
