how old was sheldon when his father died
Sheldon Cooper Sheldon contrasts strongly with his family, who are neither scientists nor intellectuals. His father George died before the start of The Big Bang Theory, when Sheldon was 14,[48] while his mother Mary is a devout born-again Christian and loving parent. Sheldon has two siblings: a twin sister, Missy, who is a tall, attractive brunette as an adult; and an older brother, George Jr., seen thus far only on Young Sheldon.[49] Both Missy and George Jr. beat up Sheldon during their childhoods, and their mother describes them to be "dumb as soup".[50] Sheldon is very fond of his maternal grandmother, whom he calls "Meemaw" and who calls him "Moon Pie".[51] He called his grandfather, who died when Sheldon was five, Pop Pop.[52] Sheldon was also very close to his grandfather, stating once that his grandfather is the only relative he had who encouraged him to become involved in science.
