The commentary team of Bobby Heenan and Gorilla Monsoon also set a precedent for the announce teams. He had been diagnosed with throat cancer in 2002 and had been in declining health in recent years.
Heenan left WWE in late 1993 planning on an early retirement, only to be tempted into a stint with rival organisation WCW where he worked for the next six years.
After a successful career at the American Wrestling Association and elsewhere, The Brain joined WWE in 1984.
WWE Chairman and CEO Vince McMahon called Heenan "one of the greatest managers and announcers in WWE history". Most fans will likely remember him for his time as a manager, and he is widely considered to be the best person to ever take that position.
Simply put, Bobby Heenan was the greatest manager in wrestling history, the standard to which all other managers would be compared.More news: Pressure grows in Ryanair to release full list of cancelled flights
Current WWE superstars and former greats were taking to Twitter on Sunday night to pay their respects to Heenan.
Heenan would go on to become one of the most popular managers in professional wrestling.
Heenan was inducted in the WWE Hall of Fame in 2004, and his death was met with many tributes within the wrestling world.
During his time in the sports-entertainment world, Heenan named several competitors under his guidance as the Heenan Family, meant to symbols the strength of their bond under any hardships and over any opposition.
WWE have extended their condolences to the Heenan family, and we at buzz.ie do the same.
