Sixers statistician Harvey Pollack died Tuesday at age 93, the organization announced. 

“Our hearts are heavy as we mourn the passing of a true NBA legend, Harvey Pollack,” Sixers CEO Scott O’Neil said in a st

atement. “He may never have laced up his sneakers, but few have done more to advance the game, in the NBA or Philadelphia basketball, than Harvey.”

An employee with the NBA since the league started in 1946, Pollack was a part of some of the most memorable NBA performances. In fact, it was Pollack who scribed out the “100″ sign that Wilt Chamberlain was photographed with after his record-setting performance.

“He did what he loved until the end, and shared that love of statistics and basketball with his family, who we remember at this difficult time,” O’Neil said. “We count ourselves incredibly lucky to have had his wealth of knowledge, indomitable spirit, passionate drive and love for our sport with us here in Philadelphia and with the Sixers for so many years. He will be missed while his legacy will endure.”

Pollack in 2002 won the John Bunn Award, a lifetime achievement honor handed out by the Naismith Basketball Hall of Fame, and is credited with beginning the league’s official tracking of offensive and defensive rebounds, steals, turnovers, blocked shots and minutes played, among other statistics — some very untraditional for their time.
