9. The Pattersons
Floyd Patterson was in the record books as the youngest fighter to win the world heavyweight championship – until another resident of the Bedford-Stuyvesant district of Brooklyn came along, Mike Tyson.
Both were mentored by Cus D’Amato and upon his retirement, Patterson adopted a 14 year old called Tracy Harris.
He had to wait until his 47th fight for a crack at world honours – and took the WBC super-bantamweight title off Thierry Jacob with a two-round KO.
