Murphy was born in 1890 in Somerville. He entered the workforce at the age of 14 and continued his education at the Somerville Evening High School. During
World War I he organized a yeomans school and was later placed in charge of recruiting for the
1st Naval District. After the war, Murphy returned to the electrical company he had worked for as a boy. He eventually became assistant sales manager; however, the job required a lot of traveling and Murphy gave it up to focus on politics. He remained with the company as a sales agent and managed a gas station. In 1918 he graduated from
Suffolk University Law School. ==Politics==
