David L. Lawrence participant of World War I
Early life
Lawrence was born into a working-class Irish Catholic family in the downtown Golden Triangle neighborhood of Pittsburgh, Pennsylvania. Too poor to attend college, Lawrence instead took a job as a clerk for Pittsburgh attorney William Brennan, the chairman of the local Democratic party and a labor movement pioneer. Brennan became a personal friend and mentor to the teenage Lawrence.
Lawrence entered the insurance business in 1916. In 1918 he entered the Army in World War I, serving as an officer in the adjutant general's office in Washington, D.C.
