'King' of golf Arnold Palmer left behind a legacy of giving back.

On Sept. 25, 2016, golf legend Arnold Palmer died at the age of 87.

The Associated Press pick for "Athlete of the Decade" for the 1960s, Palmer was a dominant force in the sporting world, winning 62 PGA Tour events, the fifth-most of any golfer in history. A true legend, Palmer is credited with helping make golf mainstream and commercialize it in America.

But less talked about than his stunning professional career are his decades of charitable work — most notably, his work with the Arnold Palmer Hospital for Children in Orlando, Florida.

During the mid-1980s, Palmer and his wife, Winnie, visited the neonatal intensive care unit and pediatrics wing at Orlando Regional Medical Center. Though staffed by talented and hardworking doctors, the facility lacked a number of resources. This, sadly, meant that many Orlando-area children would need to travel to other cities (Tampa, Jacksonville, Gainesville, Miami) for specialized care.

"We can do better than this — we should do better than this — for the children of our community," said Palmer, according to the Arnold Palmer Hospital for Children website.

Inspired by the doctors at ORMC, Palmer dedicated himself to improving their working conditions and raising the funds to open a dedicated children's hospital. In 1989, the APHC opened its doors.

In 2006, the Winnie Palmer Hospital for Women and Babies opened, expanding the work of the the APHC. Since the APHC's opening, nearly 200,000 children have been born there and at the WPHWB, with more than a million patients served.

"Making a positive change in the life of a child or young person is the most significant thing you can do," Palmer once said. "Improving the health and well-being of children is everyone's mission."

In addition to his work bringing health care to women and children, Palmer's charitable foundation, Arnie's Army, has tackled topics such as the environment and prostate cancer research, raising millions of dollars for those causes.

Palmer's work both on and off the course won't be forgotten anytime soon.

In 2004, President George W. Bush awarded Palmer the Presidential Medal of Freedom, the highest U.S. civilian honor.

"For all who love the game of golf, and for those who love to see it played, there has never been a sight in the game quite like Arnold Palmer walking down the fairway toward the 18th green," Bush said at the ceremony.

In a statement posted the morning after Palmer's death, President Obama paid tribute to the late golfer, calling him "the American Dream come to life."

Friend, rival, and fellow golf legend Jack Nicklaus honored Palmer as well, saying that he "was the king of our sport and always will be."

Arnold Palmer was a beacon of light, a hopeful figure through tough times. His life and death are reminders to be kind, to give back, and above all, to never give up.
