Recorded in over forty spelling forms from Lambert, Lambard and Limprecht, to Lambrich, Lambertini and Lemmens, this surname is almost certainly of very early German origins. As a surname it started life in the 12th century, but the derivation is from a pre 5th century personal name.
Sheldon was raised in Galveston, Texas along with his elder brother and fraternal twin sister (Missy) by his mother, Mary Cooper, an overtly devout Evangelical Christian; and George Cooper, an alcoholic who was never around.
Storyline. Leonard Hofstadter and Sheldon Cooper are both brilliant physicists working at Caltech in Pasadena, California. They are colleagues, best friends, and roommates, although in all capacities their relationship is always tested primarily by Sheldon's regimented, deeply eccentric, and non-conventional ways. They are also friends with their Caltech colleagues mechanical engineer Howard Wolowitz and astrophysicist Rajesh Koothrappali.
