He also served as assistant district attorney (1912–1916), and city attorney for six years. During World War I, he served as a member of the Lawyers Committee and the Council of Defense. A lawyer and banker, he had extensive agricultural interests throughout Curry County.^[2] A Democrat, Hockenhull was elected lieutenant governor of New Mexico in 1930 and was re-elected in 1932.^[3] He became governor upon the death of Governor Arthur Seligman in September, 1933, and completed the term ^[4] on December 31, 1934.^[5]
