Who Is Iain Armitage?
Iain Armitage is an American actor who became internationally recognized for playing Sheldon Cooper in Young Sheldon.
The sitcom was created as a prequel to The Big Bang Theory [Young Sheldon] and followed Sheldon during his childhood in East Texas.

He had to make the younger Sheldon believable while still retaining the personality traits audiences associated with the character.
Iain succeeded in doing that and remained one of the show’s central performers for its entire seven-season run. His performance also allowed viewers to watch him grow up over the course of the series. He began the show as a child and finished it as a teenager, making Young Sheldon an unusually important part of both his professional and personal development.
