Mrs. Barlow, than whom none could know Fulton better, wrote to Mr. Colden, in reply to his question about Fulton’s early life:

“Agreeable to your request I shall endeavor to give you the best information in my power respecting the early life of our excellent friend, Mr. Fulton. What is previous to 1797, when we became acquainted with him, was related by himself. He chose to have it known that he was self-educated and author of his own fortune, if I may so express it. During the summer of 1797, Mr. Fulton came to Paris to introduce his system (of canals) and get it patented. He came to lodge at a hotel where Mr. Barlow and myself were boarders. There commenced that strong affection and devoted friendship which subsisted between them in the most extraordinary degree as long as they lived. We went into our own house soon after, when my husband invited Mr. Fulton to reside with us as long as we should remain in Paris. He resided in our family as a brother for seven years. During this period he learned the French language and something of the Italian and German; studied the higher mathematics, the sciences, physics, chemistry and perspective, and in short completed his education as far as it related to his useful elegant pursuits.”

Mrs. Barlow quaintly says that Fulton’s “genteel manners, companionable and amiable qualities, acquired him many valuable friends among the nobility and gentry.” We may readily infer that not only did he choose his friends, but they chose him, because they found pleasure and profit in his company.

Mr. Colden describes him in these words: “Mr. Fulton was about six feet high; his person was slender but well proportioned and well formed. Nature had made him a gentleman and bestowed upon him ease and gracefulness. He had too much good sense for the least affectation; and a modest confidence in his own worth and talents gave him an unembarrassed deportment in all companies. His features were strong and of a manly beauty. He had large dark eyes and a projecting brow, expressive of intelligence and thought. His temper was mild, and his disposition lively. He was fond of society, which he always enlivened by cheerful, cordial manners and instructed or pleased by his sensible conversation. He expressed himself with energy, fluency, and correctness, and as he owed more to his own experience and reflections than to books, his sentiments were often interesting from their originality.

“In his home he was kind, generous, and affectionate, and he gave freely of his money to charity, to entertaining friends at home, and to further his scientific plans. But conspicuous among his virtues were his calm constancy, his industry, and the untiring perseverance which helped him to overcome all difficulties.”

Another friend wrote: “Among a thousand individuals you might readily point out Robert Fulton. He was conspicuous for his gentlemanly bearing and freedom from embarrassment, for his extreme activity, his height,—somewhat over six feet,—his slender yet energetic form and well accommodated dress, for his full and curly dark brown hair, carelessly scattered over his forehead and falling around his neck. His complexion was fair, his forehead high, his eyes dark and penetrating, and revolving in capacious orbs of cavernous depths; his brow was thick and evinced strength and determination; his nose was long and prominent, his mouth and lips were beautifully proportioned, giving the impress of eloquent utterance. Trifles were not calculated to impede him or damp his perseverance.”

A story is told by a writer in the National Portrait Gallery about the establishment of the first ferry-boat across the East River to Brooklyn, and of a painful accident which happened during the second or third trip. Some trouble occurred with the machinery, and in an attempt to start the boat the chief engineer was caught in the wheels and so injured that he died from his wounds the following day. He was carried to the house next to the home of the writer, who recalled the conversation between Mr. Fulton and the attending surgeon. Fulton exclaimed, “Sir, I will give all I am worth to save the life of that man.” When the doctor said his recovery was hopeless, Fulton turned aside, completely unmanned, and wept like a child. The neighbor truly observed that while no personal misfortune ever seemed to disturb Fulton’s calm manner, yet his feeling toward other people was sensitive and tender.

Paul Sabbaton, who was chief engineer in Fulton’s employ, wrote in later years, “I was so constantly with Mr. Fulton, saw him at his occupation, at his family fireside, and in almost every situation, that I have to this day a most distinct and strongly impressed likeness on my mind. He had all the traits of a man with the gentleness of a child. I never heard him use ill words to any one of those employed under him no matter how strong the provocation might be, and I do know there was enough of that at times; and ever and anon, my mind recurs to the time when his labors were severe. His habit was, cane in hand, to walk up and down for hours. I see him now, in my mind’s eye, with his white, loosely-tied cravat, his waistcoat unbuttoned, his ruffles waving from side to side, as his movements caused their movements; he, all the while in deep thought, scarcely noticing anything passing.”

This agrees with the statement of another employee: “His workmen were always pleased to see him about the shops. With his rattan cane in hand, he always appeared to me the counterpart of an English nobleman.”

By gathering these mind-pictures together we can form a composite likeness of a man who was great in small as well as in large affairs.
