Langdon, born in 1881 in what is now North Dakota, "hoboed" his way to Washington, D.C., and called on Roosevelt at the Navy Department, reminding him that his father, a veterinarian, had treated Roosevelt's cattle at his Dakota ranch during his ranching days. Roosevelt arranged a railroad ticket for him to San Antonio, where Langdon enlisted in the Rough Riders at age 16. He was the penultimate surviving member of the regiment and the only one to attend the final two reunions, in 1967 and 1968. He died on 29 June 1975, at the age of 94, 26 months after Brito.
