Benjamin Abram Bernstein (20 May 1881, Pasvalys, Lithuania – 25 September 1964, Berkeley, California) was an American mathematician, specializing in mathematical logic.
[1] With his Jewish[2] family, Bernstein immigrated as a child to the United States.
Along with E. V. Huntington of Harvard, Professor Bernstein was a pioneer in this field from the mathematical point of view.
... During this early period in the history of mathematical logic, a notable event for the subject was the publication of Principia Mathematica, by Whitehead and Russell.
Professor Bernstein was an intensive and critical student of this Principia and discussed it in many papers.
