Hardly the 'father of video games', seeing as how:
Cathode Ray Tube Amusement Device (1947), Thomas T. Goldsmith Jr. and Estle Ray Mann.
Chess (1947–1958), Alan Turing and Dietrich Prinz.
Bertie the Brain (1950), Dr. Josef Kates.
Nim (1951), Ferranti.
Strachey's Draughts Program (1951), Christopher Strachey.
OXO / Noughts and Crosses (1952), Alexander S. Douglas.
Tennis for Two (1958), William Higinbotham.
Mouse in the Maze, Tic-Tac-Toe (1959)
Spacewar! (1961), Martin Graetz, Steve Russell, and Wayne Wiitanen.
Odyssey (1966), Ralph H. Baer.
As you can see, Baer doesn't show up until the mid-60s, so he's not the father!
