Beall was born in Frostburg, Maryland and attended the public schools and later Gettysburg College. During the First World War, Beall served in the Ordnance Corps of the United States Army from 1918-1919. After being discharged as a sergeant, he engaged in the insurance and real-estate business.

Following the insurance business, Beall became a member of the Allegany County Road Commission in 1923. He resigned in 1930 to serve a term in the State senate, from 1930-1934. Beall went on to be a member and chairman of the Maryland State Road Commission from 1938-1939.

Beall was elected as a Republican to the Seventy-eighth and to the four succeeding Congresses, serving from 1943-1953. Beall was successfully elected to the United States Senate as a Republican in 1952, and was reelected in 1958.

In the 1964 election, Beall lost his bid for re-election to democratic candidate Joseph D. Tydings. He later returned to Frostburg and resumed his insurance business.
