Martin Abramowitz is founding president of Jewish Major Leaguers, Inc. a Boston-based not-for-profit organization that documents "American Jews in America's game." His first project, in affiliation with Fleer Trading Cards and the American Jewish Historical Society, was a 2003 baseball card set, commemorating the 142 Jewish major Leaguers from 1871 on, which sold out all 15,000 sets produced. Since then Jewish Major Leaguers has issued annual updated editions of this best-seller baseball card set. The 2009 "Record-Setters" edition combines photos and stats of all current players, plus Jewish baseball "record-setters" and "firsts," along with updated cards of career leaders and a complete all-time roster of Jewish players.
A retired vice-president of planning at Combined Jewish Philanthropies in Boston, Abramowitz lectures on his favorite subject all across the country.
