He died from a heart attack at his home in Atherton, California on November 12, 1963, and was buried at West Point Cemetery.

Tudor was acquainted with Douglas McKay, a former governor of Oregon, who was appointed Secretary of the Interior by President Dwight D. Eisenhower. In March 1953 McKay arranged to have Tudor appointed Under Secretary of the Interior. As Under Secretary, Tudor was responsible for much of the administrative work of the department. He helped select persons to run the various bureaus that were part of the Interior Department, including the Bureau of Mines, the Bureau of Reclamation, and the Bonneville Power Administration. Tudor coordinated the Department's legislative program and was involved with a number of environmental issues that arose during the early years of the Eisenhower administration, including the Hells Canyon and Echo Park controversies. Tudor served until September 1954 when he resigned to return to his construction business in California.

He returned to the Army during World War II, serving as a colonel in the Corps of Engineers from 1941 to 1945.

He married Mary Lucile Taylor in 1925, and they had one daughter.
