Iwao Takamoto, the US animator who created cartoon dogs Scooby-Doo and Muttley, has died aged 81.
Scooby-Doo was a cowardly dog but had an adventurous heart
He was responsible for characters from The Flintstones and The Jetsons when he worked for the Hanna-Barbera studio.
And he assisted in the design of films including Peter Pan, 101 Dalmatians and Cinderella, during a career spanning more than six decades.
Mr Takamoto was a vice-president at Warner Bros Animation at the time of his death, caused by heart failure.
He said he created Scooby-Doo after talking to someone who looked after Great Danes.
The dog breeder showed him pictures and "talked about the important points of a Great Dane, like a straight back, straight legs, small chin and such", Mr Takamoto explained.
"I decided to go the opposite [way] and gave him a hump back, bowed legs, big chin and such. Even his colour is wrong."
The character was named after a scat-style phrase at the end of Frank Sinatra's song Strangers in the Night, which contained the phrase "dooby-doo".
Mr Takamoto also created Fred, Velma, Shaggy and Daphne
Mr Takamoto - who also co-directed the 1973 film Charlotte's Web - was born in Los Angeles in 1925.
He received informal training in illustration techniques from fellow Japanese-Americans in a prison camp, where he spent part of World War II.
His death occurred less than a month after that of Hanna-Barbera co-founder Joseph Barbera, who was 95.
Mr Barbera's business partner, William Hanna, died in 2001.
