Mr. O'Brien made the _Shipping and Commercial List_ a strong paper and merchants quickly began to rely upon it for accurate information as regards mercantile and commercial affairs. He also issued the first annual reports of Boston's trade and commerce, and that volume has been adopted for years by the Merchants' Exchange, The work in connection with his newspaper naturally brought him into personal contact with the foremost merchants of Boston. These gentlemen who have known him intimately for forty years, have nothing but words of praise concerning his character, honesty, and business sagacity. He has witnessed the city grow from a population of 75,000 inhabitants to over 400,000, and all the changes in business methods, together with the multifarious enterprises in which Boston has engaged, are perfectly familiar to him, and he has not been backward in helping to promote such changes and enterprises as would benefit all classes of citizens. Prominent business men have not only spoken well of Mr. O'Brien, but they have given a practical illustration of their faith in him by making him the custodian of trust funds for various purposes, and in no instance has their confidence been misplaced. His financial abilities have always been acknowledged to be first-class, and therefore it is not surprising to learn that for years he has been President of the Union Institution for Savings, Treasurer of the Franklin Typographical Union, and a director in various benevolent and charitable institutions. It is very natural, in view of the business training and abilities of Hugh O'Brien, that he should be heard from in public life. Such vigorous and brainy men do not escape the attention of the people. In 1875 he took a seat in the Board of Aldermen, when the _Boston Advertiser_ referred to him as "well-known in the community and has the respect and confidence of every one." It is well known in political circles that Mr. O'Brien did not seek this office and has never been an applicant for any office. He also served as Alderman in the years 1875, 1876, 1877, 1879, 1880, 1881 and 1883, and was chairman of the Board four years.
