For more than six decades, Arum has been at the front of elite boxing and at the ripe age of 89, he is showing little signs of showing down with Fury, Lopez, Crawford and Lomachenko in his stable.
Bob Arum is a promoter who is the founder and CEO of Top Rank Boxing based in Las Vegas, Nevada. The Hall of Famer currently promotes British heavyweight champion Tyson Fury.
The 88-year-old grew up in New York and began his professional career as a lawyer after studying at Erasmus Hall High School. Arum did not have a particular interest in boxing until a chance meeting between ex-Cleveland Browns star Jim Brown led to an introduction to Muhammad Ali.
Arum admits himself that it was "The Greatest" who taught him all he knew about boxing and helped become a world-class boxing promoter.
Soon after their productive meeting, Arum was made vice president and secretary of Ali's promotional company Main Bout. This was used to host Ali's fights during the latter stages of his career.
He was joined by Mike Malitz - the son of legendary Lester M. Malitz - as a fellow vice president and had a 20 percent stake in the company.
As Ali's career in the sport winded down, Arum oversaw a rebrand of Main Bout Promotions and was later renamed as Top Rank under Arum's leadership. It was not the first time Arum had been involved in an Ali fight though.
In the 1980s, Arum's promoting credentials came into prominence. It was also the beginning of a huge rivalry with fellow American promoter Don King. For over four decades, the pair were seen as the biggest promoters in the world.

Together, they have co-promoted some of the biggest fights of all-time, including "Marvelous" Marvin Hagler vs Roberto Duran and Hagler vs Thomas Hearns.
They continued promoting the "Fabulous 4 Rivalry" by adding two massive Sugar Ray Leonard fights against Hagler and Hearns towards the end of the decade before finishing with a monumental heavyweight clash between Evander Holyfield and George Foreman.
Over the years Arum has continued to promote some of the biggest fighters in the sport.
In 1999, his services to the sport were recognised as he was inducted into the International Boxing Hall of Fame. In July 2017, Top Rank entered a new broadcasting partnership with ESPN. This started with distributing the WBO welterweight championship fight between Manny Pacquiao and Jeff Horn.
It was later announced that both parties had agreed a multi-year partnership to stream on all ESPN services, including ESPN+ before getting extended in August 2018 to run until 2025.
He has since promoted mega-events including the biggest selling heavyweight pay-per-view since Lennox Lewis vs Mike Tyson in Deontay Wilder vs Fury 2 in 2020.
