"In becoming the first Major League player to break the color barrier, Jackie will forever be an inspiration with his grace, dignity and perseverance. His story and the stories of those who never had the same opportunity must never be forgotten." -- New York Yankees
Jackie Robinson, plaque dedicated April 17, 2007. In honor of Robinson's unique place as the first African-American player of the modern era, his number 42 was retired throughout baseball on April 15, 1997, the 50th anniversary of his debut with the Brooklyn Dodgers.
Players active at the time of the number's retirement in 1997 were granted a special exemption (grandfather clause) permitting them to continue wearing the number for the remainder of their careers; the last such player still active is Yankee relief pitcher Mariano Rivera. The number will be ceremonially retired by the Yankees after Rivera retires.
The hallways are lined with classic and current photos.
