What model of Dodge van did Feynman buy in 1975? He bought a Dodge Tradesman Maxivan.

Feynman purchased the van in Long Beach, California, in 1975. It was a full-size Dodge Tradesman Maxivan with a bronze-khaki exterior and yellow-green interior, chosen as a highly visible canvas for custom murals of Feynman diagrams.

The diagrams reflected Feynman's central contribution to quantum electrodynamics. His diagrammatic method gave physicists a practical visual language for calculating interactions involving particles and electromagnetic forces, and it became one of the best-known symbols associated with modern theoretical physics.

The vehicle later acquired an unusual afterlife. Feynman's wife, Gweneth, sold it for $1 to his friend Ralph Leighton after Feynman's death. Leighton stored it, but the van began to rust. In 2012, Seamus Blackley—later known as one of the creators of the Xbox—bought it and helped bring attention back to the surviving artifact.
