Boris Moiseyevich Schein (born June 22, 1938) is a Russian-American mathematician, an expert in semigroups, and a Distinguished Professor in the Department of Mathematical Sciences at the University of Arkansas.^[1]

Schein was born in Moscow on June 22, 1938, but moved to Saratov during World War II. He became interested in mathematics as a teenager, and came under the influence of Viktor Wagner, a professor of mathematics at Saratov State University. Schein did his undergraduate studies in Mechanics-Mathematics at Saratov State, and chose to specialize in geometry, Wagner's subject. In 1958 he solved the problem of characterizing the semigroups that could be embedded into an inverse semigroup. He graduated summa cum laude in 1960. He continued working as a graduate student with Wagner, and in 1962 defended a candidacy dissertation on semigroups of transformations at the Herzen State Pedagogical University of Russia in Saint Petersburg. He accepted a faculty position at Saratov in 1963, and defended his Ph.D. theses in 1966, again at Herzen State Pedagogical University.^[1][2]

In 1968, Schein was one of the founding editors of the journal Semigroup Forum, published by Springer-Verlag. However, in the 1970s his connections with Western mathematicians led to political difficulties, his correspondence with mathematicians outside the USSR was cut off, and his students were prevented from graduating. Eventually, in the late 1970s, his mentor Wagner retired from the university and Schein was dismissed.^[1]

In 1979, Schein was able to travel to Austria with his wife and daughter, and immediately he obtained a temporary visiting position at Tulane University in New Orleans. In 1980, he took his present position at the University of Arkansas.^[1]

In 2011, Schein was named a distinguished reviewer of Zentralblatt MATH by the European Mathematical Society.^[3]
