Playwright and actor Sam Shepard has died, according to family spokesperson Chris Boneau. He was 73.

Shepard died at his home last week in Kentucky after complications from amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, Boneau said.

"The family requests privacy at this difficult time," Boneau added. Funeral arrangements will be private.

Shepard, whose work spans more than five decades, was nominated for an Oscar in 1983 for his role in "The Right Stuff." He also had a very successful career off-screen.

He won a Pulitzer Prize for drama in 1979 for his play "Buried Child," one of 40 he wrote over the years.

On the silver screen and TV, Shepard followed up "The Right Stuff" with "Steel Magnolias" in 1989, "Dash and Lilly" in 1999 (for which he earned an Emmy nod) and "Black Hawk Down" in 2001, among a slew of other projects.

More recently, he starred in Netflix's "Bloodline" in 2015 and was in this year's "Never Here," which hit movie theaters in June.

Shepard was involved with Emmy- and Oscar-winning actress Jessica Lange from 1982 to 2009, and they have two children. He also has a son from a previous relationship.

Shepard is survived by his children — Jesse, Hannah and Walker Shepard — and sisters — Sandy and Roxanne Rogers.
