Hobbs Safety, and in May 1777 was appointed justice of the supreme court, an office which he held for nearly twenty-one years. His experience with the peculiarly difficult conditions in Revolutionary New York, together with his unquestioned devotion to the patriot cause, his absolute integrity, and a reputation for sound common sense, made a combination of pub- lic qualities which caused his services to be much in demand. He was a delegate to the interstate convention at Hartford, Conn., in 1780, called "to give Vigour to the governing Powers, equal to the present Crisis," and to the Poughkeepsie convention in 1788, called to act on the draft of the new Constitution for the United States. These same traits of public character, considered in con- nection with the fact that under the new con- stitution of the state of New York the judiciary had great political power, may help to account for the apparent anomaly of a justice of the su- preme court who, according to his own state- ment, had not been bred to the profession of law. The age-limit set by this constitution would have compelled his retirement shortly, when, on Jan. n, 1798, he was elected United States senator. This office he held only until Apr. 12 of that year, when he was appointed United States district judge for the district of New York, in which capacity he served until his death in 1805. Though not a lawyer, he is said to have been partly responsible, during twenty years, for giv- ing the decisions of the New York supreme court such strength and character as they had before the days of Chancellor Kent (D. D. Barnard, quoted by Charles Warren, post, p. 293), and Kent himself said of Hobart that he was a "faith- ful, diligent and discerning judge." [F. B. Dexter, Biog. Sketches Grads. Yale Coll, vol.

When he was but three years old his father died and Alfred grew up with opportunity to attend school only between attempts to earn small sums toward the support of the family. At the age of ten he entered the home of a fanner in Westfield, Mass., remaining there until he was fourteen, when he returned to Boston to be a clerk in a Hobbs dry-goods store. Connected with this occupation for but a short time, he tried in quick succession the trades of wood-carving, carriage-body build- ing, harness making, tinsmithing, and coach- trimming. Finally he drifted into an apprentice- ship in the glass-cutting works of the Boston & Sandwich Glass Company, at Sandwich, Mass. Completing this apprenticeship in 1836, he es- tablished himself in Boston as a glass-cutter. Glass doorknobs were a staple product of his trade, and in connection with the cutting of these he invented and patented a method of fastening them into the sockets by which they were at- tached to the door locks. This invention brought him into contact with lock makers and led him to enter the business of manufacturing locks as junior partner in the firm of Jones & Hobbs. The enterprise was not a success, the partnership was dissolved, and Hobbs went to New York to sell locks and fireproof safes for Edwards & Hoi- man. This company he left to become salesman for Day & Newell, bank-lock makers of New York. Finding it necessary to prove to bankers that their locks were insecure before they would buy new ones from him, he would pick the locks of his competitors as often as opportunity afford- ed and soon became known as the most accom- plished lock expert in the country. In 1851 he accompanied the Day & Newell exhibit to the international industrial exhibition in London, where he immediately attracted attention by open- ing the best locks of Chubb, the leading English maker of the period. When he followed this feat with a successful attack upon the famous Bramah lock, which had defied picking for forty years, he not only won a prize of two hundred guineas but became conspicuous in the press of the day. The wide publicity given to his achievements created doubt as to the security of the best British locks and brought the American products into favor. Taking advantage of this condition, Hobbs formed a partnership known as Hobbs, Ashley, & Company, for the manufacture of locks at Cheapside, London. The firm introduced machine methods and enjoyed a prosperous business. In 1860 Ashley died and Hobbs welcomed the op- portunity to withdraw and return to the United States, although the firm continued under the name of Hobbs, Hart & Company. While in Eng- land he became a member of the Society of Arts, and was elected an associate member of the In- stitution of Civil Engineers, which awarded him its highest honor, the Telford Medal, for his pa- per "On the Principles and Construction of Locks." In 1860 he engineered the building and equipping of a factory for Elias Howe, Jr., manu- facturer of sewing machines, and superintended 95
