The Grand Wizard began a stint with the World Wide Wrestling Federation (WWWF) in the 1970's.
Almost immediately after his arrival in 1971, the Wizard managed Blackjack Mulligan. He later led Mr. Fuji and Prof. Toru Tanaka to two reigns with the WWWF World Tag Team Championship. A year later, the Wizard led Stan Stasiak to victory over Pedro Morales for the WWF Championship in Philadelphia on December 1, 1973. The Wizard guided a second protégé, Superstar Billy Graham, to the very same championship on April 30, 1977, when Graham overcame Bruno Sammartino in Baltimore. On February 20, 1978, Bob Backlund took on Superstar Billy Graham for the WWF Championship at Madison Square Garden and dethroned the champion. The Wizard made it his duty to gain revenge on Backlund, sending charges such as Don Muraco, Ken Patera and Greg Valentine after him.
The Wizard managed the first Intercontinental Champion Pat Patterson, and later Patera (who defeated Patterson for the title in April 1980 after the Wizard and Patterson parted ways) and Muraco to the same championship. Other protégés of the Wizard included "Beautiful" Bobby Harmon, Killer Kowalski, "Crazy" Luke Graham, Sgt. Slaughter, "Big Cat" Ernie Ladd, Ox Baker, and Cowboy Bob Orton.
On October 12, 1983, he passed away.
In 1995, he was inducted into the WWE Hall of Fame class of 1995 by his former protégé Sgt. Slaughter.
