On Monday, the legendary Ole Anderson died at the age of 81. He was a founding member of the Four Horsemen and the Minnesota Wrecking Crew with his kayfabe brother, Gene. After his in-ring career was over, he was a booker for Georgia Championship Wrestling and Jim Crockett Promotions. Later, Anderson held an executive position in WCW.

During this past week’s “WWE RAW,” Michael Cole acknowledged Anderson’s death on air before a graphic was shown. Anderson famously hated Vince McMahon (and vice versa) after he took over GCW in 1984.

Sorry to hear about the death of Ole Anderson. One of the major characters in pro wrestling of the 70s and 80s. Excellent talker and great heel.
