Arnold Palmer brought a country club sport to the masses with a hard-charging style, charisma and a commoner’s touch. At ease with both presidents and the golfing public, and on a first-name basis with both, “The King” died Sunday in Pittsburgh. He was 87.

Alastair Johnston, CEO of Arnold Palmer Enterprises, confirmed that Palmer died Sunday afternoon of complications from heart problems. Johnston said Palmer was admitted to the UPMC Hospital on Thursday for some cardiovascular work and weakened over the last few days.

“Today marks the passing of an era,” said Johnston, Palmer’s longtime agent at IMG. “Arnold Palmer’s influence, profile and achievements spread far beyond the game of golf. He was an iconic American who treated people with respect and warmth, and built a unique legacy through his ability to engage with fans.”

President Barack Obama tweeted about Palmer’s death, saying: “Here’s to The King who was as extraordinary on the links as he was generous to others. Thanks for the memories, Arnold.”
