Mary Elizabeth Thomas Peavey Brooks (November 1, 1907 – February 11, 2002) was an American politician.

[6] He drowned in a boating accident on the Snake River in 1941[7] and wasn't found for ten days,[8] which left her a widow in her early thirties with two young children.

][citation needed] Brooks was elected to the Idaho State Senate in 1964,[10] and served until 1969, when she was named to head the U.S. Mint by President Nixon in September.

President Nixon appointed Brooks director of the U.S. Mint, the third woman named to the post.

She is credited with saving the original San Francisco Mint building, known as the "Granite Lady," by transferring it to the Treasury Department.

During Brooks' tenure as Director of the Mint, she famously led a tour of the U.S. Bullion Depository at Fort Knox, Kentucky for members of Congress and the news media on September 23, 1974.
