Walter Frederick Morrison, who was credited with inventing the Frisbee, died Thursday at the age of 90.
This knowledge replaced my earlier assumption that the Frisbee was invented after a 1885 Hill Valley confrontation between Marty McFly and Biff in which McFly used one to knock a gun out of the villian's hands.
Morrison's revolutionary aerodynamic disc was inspired after he'd played with a metal cake pan on a California beach. If only everyone of us could stumble on ideas like that.
Originally called the "Pluto Platter," Morrision's contraption has gone on to sell hundreds of millions of units after he dealt the rights to Wham-o in 1957.
