For more information about Paul R. Halmos (1916-2006) and about the Paul R. Halmos Photograph Collection, please see the introduction to this article on page 1.  A new page featuring six photographs will be posted at the start of each week during 2012.

Jose Barria (1973)

 

José Barría works at the chalkboard under the inquisitive eye of Paul Halmos in May of 1973.  Barria was a doctoral student of Halmos, earning his Ph.D. from Indiana University in 1974 (Mathematics Genealogy Project).

Halmos photographed José Barría again nearly ten years later, in January of 1983.  Barría became a mathematics professor at Santa Clara University, where Halmos himself joined the faculty in 1985 and where Barría continues to publish research papers on operator theory.  Barría and Halmos published their third joint paper in 1990 while they were colleagues at SCU (MathSciNet).

Below, Robert Bartle asks Marshall Stone to sign his picture in the book of photographs of mathematicians that had already become known as the "Halmos Picture Book."  Its title was I Have a Photographic Memory and it was published by the American Mathematical Society (AMS) in 1987.  This photograph was taken in June of 1988 at Hofstra University in Hempstead, New York.

Robert Bartle and Marshall Stone

Robert (Bob) Bartle (1927-2003) earned his Ph.D. at the University of Chicago in 1951, where he would have met both Halmos, who was a faculty member there from 1946 to 1961, and Stone, who was mathematics department chair from 1946 to 1968.  Bartle was a faculty member at the University of Illinois, Urbana-Champaign, from 1955 to 1990 and at Eastern Michigan University from 1990 to 1998.  He also served for six years as editor of Mathematical Reviews and wrote well-known textbooks, including The Elements of Real Analysis (1964) and, with Donald Sherbert, Introduction to Real Analysis (1982).  (Source: AMS Notices, Feb. 2004, "Inside the AMS.")

Marshall Stone (1903-1989) probably is best known for the Stone-Weierstrass Theorem and for his leadership of the University of Chicago Mathematics Department from 1946 to 1968.  Halmos was a faculty member at Chicago from 1946 to 1961.  Stone also was a faculty member at Harvard from 1927 to 1946 and at University of Massachusetts from 1973 to 1980 (MacTutor History of Mathematics Archive).  He was AMS president in 1943-1944 (AMS Presidents).

 

Hyman Bass (1958)Halmos first photographed Hyman Bass in autumn of 1958, probably at the University of Chicago, where Halmos was a faculty member from 1946 to 1961 and where Bass would complete his Ph.D. in commutative algebra under Irving Kaplansky in 1959.  Halmos had written a paper introducing monadic algebras in 1956, and Bass's first paper in 1958 would be on this topic (MacTutor History of Mathematics). 

Hyman Bass (1968)Halmos photographed Hyman (Hy) Bass again in August of 1968 at a Joint Summer Meeting of the AMS and MAA in Madison, Wisconsin.  Bass was a faculty member at Columbia University from 1959 to 1999, where he advised at least 24 Ph.D. theses (Mathematics Genealogy Project).  During the 1990s, he turned his attention to mathematics education, eventually joining the University of Michigan faculty as Roger Lyndon Collegiate Professor of Mathematics and Mathematics Education in 1999.  He is now Samuel Eilenberg Distinguished University Professor of Mathematics and Professor in the School of Education as well.  He was AMS president in 2001-2002 (AMS Presidents).

 

Joseph Bastian

 

 

Joseph Bastian, a Ph.D. student of Halmos at Indiana University, is pictured in May of 1972 in Bloomington, Indiana.  Bastian earned the Ph.D. in 1973 with the dissertation, "Decompositions of Weighted Translation Operators" (Mathematics Genealogy Project).
