Mr. McQuillan received his education in New York City, and subsequently learned the machinist's trade. He had hardly more than completed his apprenticeship, however, and thoroughly mastered every detail of the business, when he was asked to accept a position with the Standard Oil Company, with which he has ever since been associated, having now the superintendency of their business in Bayonne. The fidelity and characteristic energy with which he has discharged every duty of this responsible position have brought him into prominence as a man of integrity and ability, and won for him a reputation which extends beyond the limits of his adopted city and county. He is known as a man of public spirit, enterprise. and progressiveness, and has filled a number of positions with ability, honor, and satisfaction.

A Democrat in politics, Mr. McQuillan early identified himself with public affairs and for some time served as Chief of the Fire Department of Bayonne. He is now serving his sixth term as a member of the Board of Aldermen of that city, and in this capacity has rendered efficient service in advancing the interests of the place and developing its resources. He is President of the Bayonne Democratic Club, and a member of the Masonic fraternity, of the Benevolent and Protective Order of Elks, of the Foresters of America, and of the Presbyterian Church.
