Earl Strom

Earl "Yogi" Strom (December 15, 1927 – July 10, 1994) was an American professional basketball referee for 29 years in the National Basketball Association (NBA) and for three years in the American Basketball Association (ABA). Strom is credited as one of the great referees in the history of the NBA and was known for his flamboyant style and ability to control the game. Nicknamed "The Pied Piper", the assertive Strom made foul calls with his whistle by using a "tweet-pause-tweet-tweet" tune and pointing at the offending player. In addition to calling fouls with flair, he was known for ejecting players from games with style and he sometimes supported his rulings with physical force.

Over the course of his career, he officiated 2,400 professional basketball regular season games, 295 playoff games, 7 All-Star games, and 29 NBA and ABA Finals. For his extensive contributions to the game, Strom was posthumously elected to the Naismith Memorial Basketball Hall of Fame in 1995. Provided by Wikipedia
