Comic artist and animator Alex Toth, who designed classic Hanna Barbera adventure cartoons such as Space Ghost, has died at the age of 77.
The veteran animator died at his home in California last week.
His son, Eric, said Toth had been in failing health for years, and died while seated at his drawing board.
Toth worked as a comic book artist in San Jose, California, in the 1950s, before moving to Hanna Barbera where he stayed throughout the 1960s and 1970s.
His other work at the legendary animation studio included characters for The Superfriends, Jonny Quest and The Herculoids.
"The work he did there touched more lives than anything else he had done," said Paul Levitz, president and publisher of DC Comics.
"He found ways to take characters like Superman from their more complicated printed form into a simpler form for animation that still held on to their power and majesty."
Before Hanna Barbera, New York-born Toth worked for Dell Comics, in San Jose, on television-led titles like Sea Hunt and Zorro.
