Peter Anthony Brock was educated at St. Peter's College, Jersey City, at St. Vincent's College, Latrobe, Pa., and at Stevens Institute in Hoboken. In 1887 he became bookkeeper for the Phillip Semmer Glass Company, Limited, of which he is now a stockholder, Director, and Treasurer. In June, 1894, he enlisted in the Second Signal Corps, New York Militia, was warranted Corporal, and on August 22, 1899, was commissioned First Lieutenant.

In political and public matters Mr. Brock has long taken an active interest, and in various capacities has gained special distinction. On November 7, 1899, he was elected to the New Jersey Assembly from Jersey City. He has been for several years especially active in matters of vital interest to wheelmen. and was one of the chief promoters and founders of the organization known as the Associated Cycling Clubs of New York, of which Judge Sims is President. He was formerly President of the old Metropolitan Association of Cycling Clubs of New York City and the Metropolitan District. The asphalt connections with the Pennsylvania Railroad ferries and the boulevard by the means of York and Mercer Streets are almost entirely due to his efforts and enterprise. Mr. Brock is thoroughly interested in the affairs of his native city, actively identified with almost every public improvement, and a popular, progressive, and patriotic citizen. His experience in business affairs, in the militia, and in-social and public life, as well as his prominence in promoting various important- movements, have won for him the confidence of the entire community, and a reputation which extends beyond the limits of Hudson County. He is a member of the Jersey City Club, of the Palma Club, and of the Catholic Club, all of Jersey City, and also of the Knights of Columbus and the Robert Davis Association. He is President of the Good Roads Association of Hudson County and Secretary of the National Cycling Association. These connections indicate in a small measure his prominence in the movement for good roads and cycling interests.
