Foss O. Eldred (1884–1956) was Attorney General of Michigan in 1946 when he was appointed to fill out an unexpired term.
He studied at Albion College and then Michigan State Normal College (now Eastern Michigan University), graduating with a degree in teaching from the latter.
He was a member of the Michigan State Senate from the 18th District from 1921 to 1924.
In 1931 he ran unsuccessfully for Congress in the Michigan 8th Congressional District, losing to Michael J. Hart by 5,000 votes largely because Eldred supported prohibition and Hart was a hard-core supporter of its repeal.
[1] He was elected mayor of Ionia in 1935 and served as a delegate to the Republican National Convention in 1940.
