An unnamed man is the husband of an unnamed woman, the father of Martin Stein, and the grandfather of Lily Stein.


On March 16, 1950, the man helped his wife deliver his son, Martin, in the back of their car.[1]

The man was a professional gambler, and he eventually taught his son how to gamble as well; Martin, however, opted for a different career path.[2] Though Martin wanted to go to MIT, his father made him become a rabbi before he would let him attend the school.[3]


According to Martin, his father never told him that he loved him. In the original timeline, Martin actually decided not to have children because he was afraid that he would become the same kind of parent that his own father had been.[4]
