Allan_Roth--Walt_Alston

Allan Roth (born Abraham Roth; May 17, 1917 – March 3, 1992) was a Canadian baseball and hockey statistician and an early proponent of sabermetrics in baseball. During his career, Roth worked for the Brooklyn/Los Angeles Dodgers as their official statistician from 1947 to 1964.
Roth is considered by many to be the father of modern sabermetrics. He was the first full-time statistician ever employed by a Major League Baseball team, creating a number of new baseball statistics over the course of his work.
