The Person:
Clarence Clifton Young (born November 7, 1922) was a United States congressman from Nevada.
A Republican, Young was elected to the U.S. House of Representatives from the state's at-large district in 1952 and re-elected in 1954. He won the Republican nomination for United States Senate in 1956 but was defeated by incumbent Democrat Alan Bible in a close race.
Young later served in the Nevada Senate and on the Nevada Supreme Court, including a stint as chief justice (1989–1990). Young also served as president of the National Wildlife Federation (1981–1983).

I also located a website devoted to courthouses of Nevada and there's a nice picture of this courthouse just after its completion in 1965 and can be viewed here.
