Walter Frederick Morrison, inventor of the Frisbee, dies at age 90

Walter Frederick Morrison, the inventor of the plastic flying discs that eventually became known as the Frisbee, died at his Utah home on Tuesday. He was 90 and is survived by three children.

For decades, Morrison's creation has been an integral part of American life. Sure, there have been other flying toys, like the Aerobie or the Flip N Flyer, but even these seem less like competitors and more like slightly-modified versions of the original toy, sort of like weird second cousins. Frisbees, whose sales have passed 200 million units, are as American as baseball, apple pie, or fireworks on the Fourth of July.
