NEW ORLEANS — Tom Benson, a successful auto dealer who brought the New Orleans Saints their only winning seasons and the “Benson Boogie,” has died. Benson, who has also owned the NBA’s New Orleans Pelicans since 2012, was 90.

The NFL and NBA teams announced Benson’s death on Thursday. He had been hospitalized since Feb. 16 with flu symptoms.

Benson made his mark in pro sports with the Saints, which he bought in 1985 when it appeared the club would be sold to out-of-state interests and perhaps moved out of Louisiana. He paid $70 million for the team, which is now worth close to $2 billion.

Benson’s business acumen helped turn the Saints from a perennial also-ran into a contender — and the 2009 NFL champion. Yet his ownership also was less flatteringly marked by the 2012 bounty scandal and by rumors Benson did not want to bring the team back to New Orleans after Hurricane Katrina devastated the city in 2005.

Benson’s death comes on the heels of an acrimonious family split that has caused some uncertainty about the future of his clubs. Benson made it known in January 2015 that he wants his third wife, Gayle, to inherit complete control of the Saints and Pelicans.
