 Raymond Louis Heenan, known to the wrestling world as Bobby "The Brain" Heenan, one of the most renowned managers and commentators in the history of professional wrestling, died on Sunday. He was 72. 
 
 Heenan battled throat cancer since 2002. He died from organ failure due to the disease, according to the Tampa Bay Times. 
 
 After early success in the World Wrestling Association (WWA) and the American Wrestling Association (AWA), Heenan was signed by the WWE in 1984. His first managerial client as part of the promotion was WWE Hall of Famer Big John Studd. 
 
 Throughout his years as a manager, Heenan formed what would come to be known as the Heenan Family, a group of superstars whom he managed. Among them were Andre the Giant, Ric Flair, Paul Orndorff, Arn Anderson, Tully Blanchard, Rick Rude, Mr. Perfect and Harley Race. All of those names also hold their rightful places in the WWE Hall of Fame. 
 
 Heenan was inducted into the WWE Hall of Fame in 2004. 
 
 Stars from the wrestling world took to Twitter to honor Heenan.

 The undeniable charisma and wit displayed by Heenan as a manager soon transitioned to the commentary table, where he formed an acclaimed pairing with Gorilla Monsoon. Their verbal exchanges, which included Heenan's one-liners with Monsoon's flabbergasted responses, set the standard for professional wrestling commentary. 
 
 Heenan left the WWE and joined WCW in 1994 but returned to the WWE when Vince McMahon bought out WCW in 2001 at WrestleMania 17 alongside Mean Gene Okerlund. They served as guest commentators for the Gimmick Battle Royal, a match featuring 19 WWE alumni.

 Triple H: Bobby Heenan Wasn't Just a Manager, One of the Greatest Wrestlers Ever 
 
 EXCLUSIVE 
 
 Bobby "The Brain" Heenan wasn't just a legendary wrestling manager -- he was also INCREDIBLE when it came to throwin' down in the squared circle ... so says Triple H. 
 
 The WWE executive tells TMZ Sports most people don't know about Heenan's wrestling skills -- "He was one of the best in-ring performers there was. He just chose not to do it." 
 
 And why not? 
 
 "He wanted to be a manager. That's what he wanted to do." 
 
 Heenan was obviously damn good at the managing thing -- rising to legendary status managing stars like Andre the Giant, Ravishing Rick Rude, Mr. Perfect and more in his storied career. 
 
 Triple H also says one of his favorite Heenan moments was his 2004 WWE Hall of Fame induction speech -- which Bobby performed without a single scripted note.

Heenan was diagnosed with throat and tongue cancer in 2002 and spent the last several years battling the disease, including losing the ability to talk after multiple surgeries on his tongue and the reconstruction of his lower jaw.
– Legendary World Wrestling Entertainment manager and commentator Bobby "The Brain" Heenan died Sunday at age 73, reports ESPN, which calls Heenan "one of the most renowned managers and commentators in the history of professional wrestling." A cause of death hasn't been confirmed, but Heenan had been fighting throat and tongue cancer since 2002. Heenan came to the WWE in 1984 after first working with other wrestling organizations; he ended up building the "Heenan Family," a group of wrestlers he managed that included such big names as Andre the Giant and Ric Flair. He also went on to have massive success as a commentator after retiring as a manager in the '90s, and WWE exec Triple H tells TMZ Heenan was also an extremely talented wrestler—he simply "wanted to be a manager," Triple H says. "That's what he wanted to do." Heenan left WWE in 1994 for World Championship Wrestling, but he returned to the WWE when Vince McMahon bought out WCW in 2001. He was inducted into the WWE Hall of Fame three years later. McMahon and Flair were among those mourning Heenan on Twitter, with Flair calling him "The Greatest Manager, One Of The Greatest Announcers, And One Of The Best In-Ring Performers In The History Of The Business" and McMahon calling him "One of the greatest managers and announcers in WWE history." UPROXX rounds up some of Heenan's greatest quotes, including: "I know all about cheating. I've had six very successful marriages." The truth? He was married just once, in 1974. In addition to wife Cynthia Jean, he leaves behind a daughter and a grandson, the Los Angeles Times reports.
