(CNN) -- Walt Disney Studios Chairman Richard Cook announced Friday he was resigning his post, effective immediately.
"I have loved every minute of my 38 years that I have worked at Disney...from the beginning as a ride operator on Disneyland's steam train and monorail to my position as chairman of The Walt Disney Studios," Cook said in a statement.
He said his decision came after lengthy contemplation, and quoted baseball great Yogi Berra, "'If you come to a fork in the road, take it.' "
Robert Iger, president and CEO of the Walt Disney Co., said in a statement that Cook's work had "truly enriched this company and significantly impacted Disney's great legacy."
"We thank Dick for his tremendous passion for Disney, and his many accomplishments and contributions to The Walt Disney Studios, including a very promising upcoming film slate," Iger's statement said. "On behalf of everyone at Disney, we wish him the best with all the future has to offer."
