Wald (1902–1950) was born in Rumania and emigrated to the United States in 1938. From 1938, he worked at Columbia University. In 1939, he published the first account of statistical decision theory, and in 1943, he developed the probability ratio test, the essential feature of sequential analysis. He often used Bayesian arguments to derive frequentist results. He worked on a wide range of topics in mathematical statistics and econometrics.
