The Big Bang Theory Wiki

This unnamed man is the first ex-husband of Missy Cooper, the father of her son and her second child, the ex-brother-in-law of Sheldon Cooper and George Cooper Jr., and the ex-son-in-law of Mary Cooper.

Sheldon went to Texas to aid in the birth of his first nephew because Missy's husband had been in a terrible motorcycle accident and was recovering from it. Neither Sheldon's nephew's name nor his brother-in-law's name are mentioned. 

Missy tells Raj that she and her husband are separated and even her mother seems to wants to ignore that fact and that she is also pregnant. (The Bow Tie Asymmetry)

Adult Sheldon says: "One day she said the same thing to her first husband. I like to think I prepared her for that moment." Thus Sheldon confirmed that this man and Missy eventually divorced and she later remarried to another man. (Pish Posh and a Secret Back Room)



  • Since Missy's problems with her first husband began when she was pregnant with their second child, then most likely the father of her third and fourth children is her second husband.
