Senator William Emerson Brock

William Emerson Brock (born March 14, 1872) was a Democratic politician who represented the state of Tennessee in the United States Senate. A member of the Democratic Party, he served as a senator for Tennessee from September 2, 1929, to March 3, 1931. His tenure in the Senate marked his service as a federal legislator during the late 1920s and early 1930s, a period of significant political and economic change in the United States.

Brock served one term in the Senate, leaving office as a former senator after March 3, 1931. During this time, he held the role of Senator without a specified district, as is customary for members of the U.S. Senate, who represent their entire state. While details of his committee assignments, office room, and other aspects of his public life are not provided in the available record, his service as a United States Senator from Tennessee between 1929 and 1931 remains the central known element of his political career.
