Henry Leavitt Ellsworth - Patent Office

Patent Office

In 1835, Ellsworth was elected mayor of Hartford, Connecticut, but had served only a month when he was appointed the first Commissioner of the U.S. Patent Office, an office he held for ten years, from 1835 until 1845. His twin brother William W. Ellsworth was Governor of Connecticut from 1838 to 1842, and served as a U.S. Congressman from Connecticut as well. William Wolcott Ellsworth was married to the daughter of Noah Webster, the publisher of the eponymous dictionaries.

When he arrived at the Patent Office, Ellsworth found one third of the floor-space in his office occupied by over 60 models of inventions; he moved them to a separate room. He also found that no list of patent applicants had ever been drawn up, a deficiency he soon corrected.

Acting as Patent Commissioner, Ellsworth made a decision that profoundly affected the future of Hartford and Connecticut. The young Samuel Colt was struggling to establish a firm to manufacture his new revolver. Ellsworth became interested in Colt's invention, and in 1836 made the decision to issue Colt U.S. Patent No. 138. On the basis of Ellsworth's decision, Colt was able to raise some $200,000 from investors to incorporate the Patent Arms Manufacturing Company of Paterson, New Jersey, the forerunner of the mighty Colt arms manufacturing empire.

In today's world Ellsworth would be described as an early technology adapter. He became so interested, for instance, in a new-fangled invention by Samuel Morse called the telegraph that Ellsworth petitioned Congress for a $30,000 grant to test the possibilities of the technology.

From Ellsworth's exposure to the West and knowledge of inventions, he prophesied late in life that the lands of the West would be cultivated by means of steam plows. This prophecy was introduced in the probate of his will in an attempt to prove that he was of unsound mind.

Ellsworth was proven correct, of course, and his interest in agriculture during his time as Patent Commissioner induced Congress in 1839 to appropriate the first monies for farming, which were used to collect seeds from foreign countries and distribute them through the United States post office, as Ellsworth had urged. By 1845 Ellsworth's patent office was performing the functions of a full-fledged agricultural bureau. For this accomplishment Ellsworth earned the sobriquet "Father of the United States Department of Agriculture."

A comment by Ellsworth about the increased workload at the patent office, taken out of context and embellished, was apparently the source of an urban legend that a patent office official (Charles H. Duell in some versions) claimed that everything which could be invented had already been invented.

Following Ellsworth's stint in the Patent Office, he settled in Lafayette, Indiana, acting as an agent for purchase and settlement of public land, but in 1857 he returned to Connecticut. Ellsworth later served as an early president of the Aetna Insurance Company. He was an early benefactor of Yale College, donating some $700,000 to his alma mater, as well as title to the Ellsworth lands in the former Western Reserve.
