Henry Helson

Halmos photographed harmonic analyst Henry Helson (1927-2010) in March of 1966 in Irvine, California. Helson earned his Ph.D. in 1951 from Harvard under advisor Lynn Loomis. In 1955, he joined the faculty at the University of California, Berkeley, and went on to advise 20 Ph.D. students during his career there.

Henry Helson

Halmos photographed Henry Helson again on January 17, 1974, at the Joint Mathematics Meetings in San Francisco, California.

I N Herstein

Halmos photographed ring theorist Yitzchak (Israel) Herstein (1923-1988) in April of 1984 at the University of Notre Dame in South Bend, Indiana. Herstein earned his Ph.D. in 1948 from Indiana University with the dissertation “Divisor Algebras” written under Max Zorn. In 1951, he became a faculty member at the University of Chicago, where Halmos also was on the faculty. Herstein left Chicago in 1953 to teach at the University of Pennsylvania and Cornell, but returned to Chicago in 1962 and spent the rest of his career there. Halmos left Chicago for Michigan in 1961.

Magnus Hestenes

Numerical analyst Magnus Hestenes (1906-1991) was photographed by Halmos on March 30, 1966, in Irvine, California. Hestenes earned his Ph.D. in 1932 from the University of Chicago under advisor Gilbert Ames Bliss. After serving as a faculty member at Chicago for several years, he joined the faculty at the University of California, Los Angeles, in 1947 and spent the rest of his career there. Best known for developing the conjugate-gradient method for solving linear systems, he advised 35 Ph.D. students at Chicago and UCLA.

Hestenes,” in The History of Numerical Analysis and Scientific Computing, SIAM, and “Requiem for the Skillful,” by Saunders Mac Lane, AMS Notices 44:2, February 1997.)

Edwin Hewitt

Halmos photographed Edwin Hewitt (1920-1999) in November of 1968 in Tucson, Arizona. Hewitt earned his Ph.D. in 1942 from Harvard under advisor Marshall Stone. He became a faculty member at the University of Washington in Seattle in 1948 and spent the rest of his career there. At Washington, he advised 37 Ph.D. students, including former MAA president Ken Ross, with whom he wrote several papers and a book on harmonic analysis.

Graham Higman

Group theorist Graham Higman (1917-2008) was photographed by Halmos on June 20, 1968, in London, England. Higman earned his Ph.D. in 1941 from Oxford with the dissertation “The Units of Group-Rings,” written under Henry Whitehead. In 1946, after doing non-mathematical war work from 1940 to 1946, he joined the mathematics faculty at the University of Manchester, where he worked in group theory with Max Newman, Bernhard Neumann, and Hannah Neumann. He moved to Oxford University in 1955 and remained there until he retired in 1984. His 50 Ph.D. students included the group theorist Peter Neumann, son of Bernhard and Hannah Neumann.
