Walter Fredrick Morrison, the man credited with inventing the Frisbee, has died. He was 90.
Morrison's son, Walt, told The Associated Press on Thursday that "old age caught up" with his father and that he also had cancer.
Utah House Rep. Kay McIff, an attorney who represented Morrison in a royalties case, said Morrison died at his home in Monroe, Utah, on Tuesday.
"That simple little toy has permeated every continent in every country," McIff said. "How would you get through your youth without learning to throw a Frisbee?"
Walter Morrison sold the production and manufacturing rights to his "Pluto Platter" in 1957. The plastic flying disc was later renamed the "Frisbee," with sales surpassing 200 million discs. It is now a staple at beaches and college campuses across the country and spawned sports like Frisbee golf and the team sport Ultimate.
According to Kennedy, Morrison and his future wife, Lu, used to toss a tin cake pan on the beach in California. The idea grew as Morrison considered ways to make the cake pans fly better and after serving as a pilot in World War II, Morrison began manufacturing his flying discs in 1948.
He is survived by three children.
