Ken Spears, who co-created the animated series Scooby-Doo with Joe Ruby in the 1960s , passed away last Friday at the age of 82 from dementia. His son Kevin Spears reports this to the American Variety on Monday .

Spears co-founded the production studio Ruby-Spears Productions Ruby and made numerous animated series, including Superman , Alvin and the Chipmunks and Mister T . His business partner Ruby passed away in August of this year at the age of 87.

Spears began his career as a sound engineer in a Los Angeles production studio. There he met Ruby, with whom he would continue to work for the rest of his career.

In the 1960s they came up with the idea for an animated series about a detective team who solve mysteries together with a dog. This eventually resulted in the Scooby-Doo series , with drawings by Iwao Takamoto.

From Scooby-Doo, Where Are You! initially two series were made. Numerous television sequels and spin-offs followed later. Cinema films were also made.
