Dennis Chavez

(Wikipedia) Dionisio "Dennis" Chávez (April 8, 1888 – November 18, 1962) was a Democratic politician from the U.S. state of New Mexico who served in the United States House of Representatives from 1931 to 1935, and in the United States Senate from 1935 to 1962. He was the first Hispanic Democrat elected to the US Senate.
... Chávez was the Democratic nominee for U.S. Senator from New Mexico in 1934. He lost narrowly to Republican incumbent Bronson M. Cutting. However, Cutting was killed in an airplane crash on May 6, 1935, and five days later, Chavez was appointed to fill the vacancy pending a special election. In 1936, Chávez was elected to the remaining four years of Cutting's term, and then won a full term of his own in 1940, becoming the first person of Hispanic descent to be elected to a full term in the U.S. Senate. (Octaviano Larrazolo, also from New Mexico, was the first Hispanic to be elected to the Senate, but he was only elected to the remainder of an unexpired term and never served a full term.)
Chávez was re-elected again in 1946, 1952 and 1958, and served until his death in 1962. He served as chairman of the Committee on Public Works from 1949 to 1953, and again from 1955 until his death. Continued
