Walter White worked in a Car Wash during the first season, that later would serve to launder money.
Walter Hartwell White (also known by his clandestine alias Heisenberg) is the main protagonist of Breaking Bad, portrayed by Bryan Cranston. Walt lives in Albuquerque, New Mexico, where he works as a high school chemistry teacher. After being diagnosed with Stage IIIA lung cancer, he resorts to manufacturing methamphetamine and drug dealing to ensure his family's financial security after his death. Series creator Vince Gilligan has described his goal with Walter White as 'turning Mr. Chips into Scarface', and deliberately made the character less sympathetic over the course of the series. Walt's transition from mild-mannered school teacher and family man to ruthless criminal mastermind and murderer is the show's central focus.
