Walter Morrison, inventor of the Frisbee has died. →[More:]It seems that the Frisbee was originally called the Pluto Platter by Morrison, who made the early discs and sold them at fairs. Even better, the story of the idea deriving from the Frisbee Pie company tins is half true. That's where Wham-O got the name. And Morrison did get the idea from playing with a cake tin on the beach.
