Thomas George Lanphier, Jr., American colonel and pilot (born 1915)

Thomas George Lanphier Jr. was a Panama-born American colonel and fighter pilot during World War II who was first given sole credit, then later partial credit shared with Rex T. Barber, for shooting down the plane carrying Admiral Isoroku Yamamoto, the commander in chief of the Imperial Japanese Navy. Most modern historians discount his version entirely, giving Barber the whole credit for the kill.
