Bill James

George William James (born 1949) is an American baseball writer, historian, and statistician whose work has been widely influential. Since 1977, James has written more than two dozen books about baseball history and statistics. His approach, which he named sabermetrics after the Society for American Baseball Research (SABR), scientifically analyzes and studies baseball, often through the use of statistical data, in an attempt to determine why teams win and lose.

In 2006, Time named him in the Time 100 as one of the most influential people in the world. In 2003, James was hired as senior advisor on Baseball Operations for the Boston Red Sox and worked for the team for 17 years during which they won four World Series championships.
