Los Angeles (CNN) -- Cartoonist Jerry Robinson, who worked on the earliest Batman comics and claimed credit for creating the super-villain The Joker, died Thursday at the age of 89, his family confirmed. 

"Batman has lost another father," Batman movie producer Michael Uslan said. "Farewell to my dear, dear friend, mentor and idol, Jerry Robinson." 

Spider-man co-creator Stan Lee, who was with rival Marvel Comics, called him "a genuine talent and a genuine gentleman." 

"Jerry Robinson was not only one of the finest artists ever to illustrate comic books, but he was also the head of an editorial syndicate which made cartoons available worldwide, as well as being an inspiration to young artists, whom he always found time to help and advise," Lee said. 

Robinson, in a panel discussion at New York Comic Con in 2009, said he was a 17-year-old creative writing student at Columbia University when he was hired as a writer and illustrator at DC Comics. 

Though he was initially just assisting Batman creators Bob Kane and Bill Finger, his chance to create The Joker came in 1940, when the demand for more Batman stories overloaded Finger. 

"This was going to be a problem, so I volunteered to do one of the stories," Robinson said. 

He handed in the work for a grade in his college creative writing class, he said. 

"I wanted a very strong villain, because I thought that's going to carry the story," Robinson said. "Villains are more exciting." 

He wanted his villain to have a sense of humor, and "in a space of hours" one night "somehow The Joker came out," Robinson said. The first Joker image was modeled out of the joker card in a deck of playing cards, he said.  QUESTIONS:
