Halmos in Hawaii

Paul Halmos served as chair of the mathematics department at the University of Hawaii in Honolulu during 1968-69 and he had many mathematical visitors during this time. (See page 2 and page 10 of this collection, for instance.)  Four of his visitors during 1969 were Ivan and Crina Singer and Allen and Joan Shields. Allen Shields (1927-1989) visited the University of Hawaii for a semester from his home campus, the University of Michigan (where Halmos had been a professor from 1961 to 1968), while Ivan Singer visited UH for one week from much farther away, Romania. Actually, Singer was a Visiting Professor at the University of Iowa in 1969, and he and Crina traveled during the Winter Break to the West Coast of the U.S. so that he could give a series of talks and to Honolulu, Hawaii, for one week so he could work with Halmos. Besides doing mathematics, Singer remembers that he and Crina spoke Hungarian with Halmos because he wanted to practice it and that they had a wonderful time as tourists, taking in, for instance the Kodak Hula Show, and as guests of Paul and Virginia Halmos.

Ivan Singer now is Research Professor and Honorary Member of the Institute of Mathematics of the Romanian Academy in Bucharest. He is a functional analyst currently researching geometry in semi-modules, and also interested in optimization, convex and discrete geometry, and operations research. Photographs of (and by) Singer appear on page 36 and page 58 of this collection, where you can read more about him. Allen Shields is pictured on page 48 of this collection, where you can read more about him.
