Sheldon was born in Galveston, Texas. He and his brother (George Jr.) and twin sister (Missy) were raised by their father (George) and mother (Mary).

Sheldon has been a child prodigy since he was a child, and many remarkable achievements in his childhood can prove this: he built a computer tomography scanner that didn't work properly, burned his sister's guinea pig "Snowball", a so-called "sonic death ray" and an armed robot modified from Missy's toy oven.

Sheldon's idols are Hawking and Einstein, and his future ideal is to study theoretical physics. Another option is to be a professional railway station ticket inspector or a tramp.
