"A man of rare mechanical ability. His inventions bear the stamp of originality and the evidences of a powerful mind. His talents are found to be of great service everywhere in our establishment, but most especially in our printing-office, of which, he has a general supervision. "
"Invention was his hobby, and he rode it well:-- indeed, it became his blessed safety valve. He early contrived a horseshoe with adjustable caulks for slippery weather which received a bronze medal at a Boston Mechanics Fair of that period.
Michael Anagnos, Perkins Director on Dennis A. Reardon:
"His inventions bear the stamp of originality and the evidences of a powerful mind. His talents are found to be of great service everywhere in our establishment, but most especially in our printing-office, of which, he has a general supervision. In the words of the director, "His mechanical genius, power of putting perfection into the minutest details, and love of the simple and beautiful, are remarkable mental characteristics, and are of great use in the planning and execution of our improvements in the best and most economical manner. It is a striking instance of the power of the mind to overleap outward barriers, that, where experienced workmen have been baffled by mechanical difficulties and unforeseen obstructions, his keen insight and correct judgment have invariably found a way out of every dilemma." The system of electric bells which are placed in different parts of the establishment, and rung simultaneously by a clock, is not the least of Mr. Reardon's inventions; and the perfection of our new press, in the planning of which he has had a prominent part, is another proof of his mechanical genius."
