Michael E. Heisley (March 13, 1937 – April 26, 2014) was an American businessman and former majority owner of the Memphis Grizzlies. He orchestrated the move of the team from Vancouver in 2001, after promising to keep the franchise in Vancouver when he purchased it in 2000. He agreed in 2006 to sell his 70% controlling stake in the Grizzlies to a consortium including Christian Laettner and Brian Davis, but the group missed a deadline for the purchase and Heisley found no other bidder willing to meet the team's $300M asking price.
In 2012 Heisley decided to sell the Grizzlies and step aside from all of his corporate interests due to his advancing age. The team announced on June 11, 2012, that Ubiquiti Networks founder Robert J. Pera would be purchasing the team, but Heisley will remain on board until the sale is finalized.
Heisley died on April 26, 2014, of complications of a stroke. He was 77.
