The Times reports in its a brilliant obituary:
...Paul Anthony Samuelson was born on May 15, 1915 in Gary, Ind., the son of Frank Samuelson, a pharmacist, and the former Ella Lipton. His family, he said, was “made up of upwardly mobile Jewish immigrants from Poland who had prospered considerably in World War I, because Gary was a brand new steel town when my family went there.”The Times observes further,
...In 1940, Harvard offered him an instructorship, which he accepted, but a month later M.I.T. invited him to become an assistant professor.
Harvard made no attempt to keep him, even though he had by then developed an international following. Mr. Solow said of the Harvard economics department at the time: “You could be disqualified for a job if you were either smart or Jewish or Keynesian. So what chance did this smart, Jewish, Keynesian have?”
Indeed, American university life before World War II was anti-Semitic in a way that hardly seemed possible later, and Harvard, along with Yale and Princeton, was a flagrant example..
