Mr Morrison, who died this week at age 90, called his earliest flying disks "Whirlo-Way" and "Pluto Platter," to capitalise on the flying saucer craze of the 1950s.
But it wasn't until he licensed the invention to the Wham-O Manufacturing Co. in 1957 that sales took off. Wham-O rechristened the disks Frisbees and removed the flying-saucer-like portholes. Sales eventually reached the hundreds of millions, making it one of the most popular toys of the 20th century.
In the 1960s, the Frisbee became identified with the counter-culture and with movie stars like Richard Burton and Julie Andrews, who affirmed they were fans. The disks even inspired new sports, including Frisbee Golf and Ultimate.
