Pete Palmer

At night, after his co-workers had left for the day, Palmer used the company's (at the time) cutting-edge computers to run advanced simulations analyzing historical baseball statistics.

In 1982, he gained notoriety when he recognized a scorekeeper's error which counted a 1910 Detroit Tigers box score twice, crediting Ty Cobb with an extra two hits and three at-bats.

Palmer also innovated the Linear Weights method of estimating a player's offensive contributions, an invention that will likely be his lasting legacy.

Palmer, with help from Dick Cramer, invented OPS (on-base plus slugging) in 1978, which now is universally accepted as a measure of batting ability.

In 1973, he joined the stat crew of the New England Patriots, compiling the official statistics for the team's home games.
