Milton Abramowitz
Milton Abramowitz was a Jewish American mathematician at the National Bureau of Standards who, with Irene Stegun, edited a classic book of mathematical tables called Handbook of Mathematical Functions, widely known as Abramowitz and Stegun. Abramowitz died of a heart attack in 1958, at which time the book was not yet completed but was well underway. Stegun took over management of the project and was able to finish the work by 1964, working under the direction of the NBS Chief of Numerical Analysis Philip J. Davis, who was also a contributor to the book.
The major work of producing reliable mathematical tables, as described above, was part of the WPA project of Franklin Roosevelt.
