Eastburn and Gray’s origins date back to Aug. 14, 1877, when Hugh B. Eastburn was admitted to the Bucks County Bar. Hugh B. Eastburn served as district attorney of Bucks County from 1885 to 1888 while he continued his private practice. His son, Arthur M. Eastburn Sr., graduated from the University of Pennsylvania Law School in 1911 and subsequently, the father-son team practiced law together until Hugh’s death in 1915. Arthur Eastburn Sr. would serve as district attorney of Bucks County from 1926 to 1938 while maintaining his legal practice.

In 1938, Samuel S. Gray Jr. joined Arthur Eastburn Sr. and the firm name changed to Eastburn and Gray. In 1941, Gray left the office for active duty with the 28th Infantry Division, eventually rising to the rank of colonel. He saw combat in the European Theater and served as a military governor until 1946 when he returned to Doylestown to practice law. Gray would go on to serve as the solicitor of Bucks County from 1960 to 1970.
