Who inspired Lex Fridman to wear a suit?

Lex Fridman was inspired to wear a suit, specifically a black suit and tie, as a reaction against the casual dress culture prevalent in academia and the tech industry, including places like Google. He aimed to take himself and each moment seriously, which he felt a suit helped achieve. Among the people he looked up to who influenced this style choice was the physicist Richard Feynman, whom Fridman admired for his class, humor, and brilliance. Additionally, the classic style of the "Mad Men" era also played a role in his decision to adopt this formal way of dressing, as it allowed the focus to be on his character rather than fashion or attire 1.
