In particular, Wald and his family were persecuted as Jews. When Nazi Germany annexed Austria in 1938, the discrimination against Jews intensified. However, Oskar Morgenstern created a position for Wald in economics. ĭespite Wald's brilliance, he could not obtain a university position because of Austrian discrimination against Jews. In 1927, he entered graduate school at the University of Vienna, from which he graduated in 1931 with a Ph.D. In 1928, he graduated in mathematics from the King Ferdinand I University. His parents were quite knowledgeable and competent as teachers. A religious Jew, he did not attend school on Saturdays, as was then required by the Hungarian school system, and so he was thus homeschooled by his parents until college. Wald was born on 31 October 1902 in Kolozsvár, Transylvania, in the Kingdom of Hungary.
