George Cooper Sr. was the father of Sheldon Cooper, George Cooper Jr. and Missy Cooper, and husband of Mary Cooper. He has been described as an almost-redneck, “Homer Simpson” Texan throughout the series.
He died in 1994, approximately 13 years before the series began.
When Sheldon was 12, he did a series of experiments involving the height of stairs. He increased the height of some stairs by 2 millimeters and as a result George tripped and broke his clavicle (“Pilot”).
Mary claims that he wasn’t so wise and once tried to fight a bobcat for some licorice. Sheldon claims that his father used to make him watch and play football, since it was popular in Texas, despite Sheldon’s lack of interest for it, however the learning of the sport gave Sheldon something to know about other than Science.
His twins: Missy and Sheldon Cooper
George also taught Sheldon how to cook meat as if it were chicken, and archery (which gives Sheldon a smell of K-Mart bourbon whenever he plays it, implying his father was drinking during teaching) and how to shoot close enough to a raccoon that it “craps itself.”
