Daniel Baugh Brewster Sr. (1923-2007) was an American attorney, military officer, and Democratic politician who represented Maryland in the U.S. Congress during the mid-20th century. Born in Baltimore, Maryland, he attended local schools including Baltimore Polytechnic Institute before serving as a combat infantryman in the U.S. Army during World War II in Europe, earning decorations for his service. After the war, he graduated from Loyola College in Baltimore (1946) and the University of Maryland School of Law (1950). Brewster's political career began in the Maryland House of Delegates (1950-1958), where he focused on education and labor rights. He was elected to the U.S. House of Representatives for Maryland's 2nd congressional district (1959-1963) before winning a U.S. Senate seat in 1962, serving from 1963 to 1969. As a senator, he was a key figure in Maryland politics during the 1960s, aligning with the liberal wing of the Democratic Party under Presidents Kennedy and Johnson. He supported civil rights legislation including the Civil Rights Act of 1964, was involved in Great Society programs, and ran as a 'favorite son' candidate in the 1964 Maryland Democratic presidential primary to counter segregationist George Wallace. His Senate work included committee assignments on armed services and labor, reflecting his military background and interest in veterans' affairs. Brewster lost re-election in 1968 and later faced legal troubles, pleading no contest in 1975 to a misdemeanor charge of accepting an illegal gratuity related to bribery allegations, for which he was fined $10,000 and received a suspended sentence. Post-politics, he returned to private law practice in Maryland until his death in 2007.
