Person: Herstein, Israel Nathan
Yitz Herstein was a Polish mathematician who worked in America. He worked on ring theory but he is best known for his algebra textbooks.
Mathematical Profile (Excerpt):
 Yitzchak is the Hebrew version of Isaac but when he was in primary school his teachers called him Israel and he was known by that name ever since.
 In fact, like Yitz, Chaim was later not known by that name but called Harvey.
 After his marriage to Marianne Deson, Herstein moved to the University of Indiana and received a Ph.D. in 1948 for a thesis Divisor Algebras written under Max Zorn's supervision.
 In Chicago, Herstein was influenced by Abraham Albert.
 His appointment as Assistant Professor at Chicago was in Mathematics and Economics and Herstein published some papers relating to economics while holding the post.
 A A Albert was chairman of the Mathematics Department at Chicago and had been desperate to bring Herstein back there.
 The faculty approved Herstein's appointment.
 In addition to work on rings and algebras Herstein also worked on groups and fields.
 Herstein is perhaps best known for his beautifully written algebra texts, especially the undergraduate text Topics in algebra (1964).
 Topics in Ring Theory was based on lectures Herstein gave at the University of Chicago and first published in the University of Chicago Mathematics Lecture Notes series.
 The book largely concerns Herstein's work on Lie and Jordan structure of simple associative rings which he published in various papers in the early 1950s.
 Matters mathematical by Herstein and Kaplansky is an interesting book, based on a course designed to introduce students who were not specialising in mathematics.
 Herstein supervised 30 research students.
 Often Yitz would take us to Mama Luigi's for a late dinner, where we talked for hours.
 (Yitz kept an automobile in storage in Rome for his frequent visits there  but he was equally at home in all of the world's great cities.) ...
Born 28 March 1923, Lublin, Poland. Died 9 February 1988, Chicago, Illinois, USA.
