Mr Gearloose, or Newton's Father, is a male anthropomorphic cockatoo.
The brother of Gyro Gearloose, this man presumably took a wife at some point prior to the mid-1950's, and, at any rate, became the father of Gyro's whiz nephew Newton.
He may or may not be the same individual as a arrogant chemist bearing an eerie resemblance to Gyro whom Donald Duck met in 1973.
Behind the scenesEdit
The existence of a male sibling of Gyro's is implied by that of Newton Gearloose, who debuted in 1965 in The Copycat Inventor.
