It is gathered that the Tom and Jerry director died on Thursday night at his apartment in Prague in the Little Quarter area.
He was born in Chicago but moved to Prague in 1959 after what was only supposed to be a 10-day visit.
But he fell in love with his future wife, Zdenka and stayed in the Czechoslovakian capital.
Born Eugene Merrill Deitch, he directed 13 episodes of Tom and Jerry and several episodes of the series Popeye.
Gene was the co-producer of Sidney’s Family Tree which was nominated for an Academy Award in 1958.
The animator and illustrator won the Academy Award for Best Animated Short Film for Munro in 1960.
In 2004 he was presented with the Winsor McCay Award for his lifelong contribution to animation.
