Jackson above all kind. He was public spirited, being one of the prime movers for an improved public school system in Wisconsin, and he endowed a professorship of law in the University of Wis- consin. Though not markedly original, he was a pleasing public speaker. His health was never robust. [The best sketch of Jackson is by Wilshire C. But- terfield in the Mag. of Western Hist., Jan. 1887.

James, 1777-1867, and Charles Jackson [qq.v.] were his brothers. His maternal grand- father, Patrick Tracy, had migrated penniless from Ireland, but had raised himself to a position of opulence and public esteem in the city of New- buryport. His father enjoyed a distinguished career as a member of the Continental Congress in 1782, supervisor of internal revenue for the Boston district, treasurer of Massachusetts, and treasurer of Harvard College. Educated in the Newburyport schools and at Dummer Academy, Jackson was apprenticed at the age of fifteen to William Bartlett, at that time the richest and most enterprising merchant of Newburyport Skill and industry soon won him the confidence of his master and before he had reached the age of twenty he was dispatched as supercargo on a voyage to St. Thomas with authority superior to the captain. His success in this venture led his elder brother, Capt Henry Jackson, to offer him in 1799 the position of captain's clerk on his ship bound for the Far East, and Bartlett gen- erously relinquished his claims of apprenticeship to enable the boy to take advantage of the op- portunity. Following this trip Jackson took command of ship and cargo for three successive voyages, the last of which occupied four years and was com- pleted in 1808. Having accumulated some capi- tal, he retired from the sea and established him- self as a Boston merchant specializing in trade with the East and West Indies. Although he was on the verge of bankruptcy in 1811, by his energy and integrity in combination with his first-hand knowledge of trading conditions he was enabled eventually to amass a fortune and to win the confidence of his associates. His shipping interests were severely curtailed by the War of 1812, but he speedily found an outlet for his energy and organizing genius in the manu- Jackson facture of cotton. Shortly after the outbreak of the war his brother-in-law, Francis Cabot Lowell, returned from England full of enthusiasm for establishing a textile factory. Jackson was quickly won to the scheme and with Nathan Ap- pleton and a few close friends organized in 1813 the Boston Manufacturing Company and built a mill on the Charles River at Waltham. It was in this mill that the machinery designed and built by Lowell and Paul Moody was set up and it was here that for the first time probably in the world all the operations for converting the raw cotton into the finished cloth were brought to- gether in one factory. Jackson was in immediate charge of the Waltham mills, and he speedily became so interested in textile manufacture that he relinquished his other projects. Aided by the tariff of 1816, the manufacturers extended their operations at Waltham to include the local power resources. In 1820 Jackson and his associates, in search of a location for further extensions, decided upon East Chelmsford on the Merrimac River. They purchased the land bordering the river, erected cotton factories, and christened the new community Lowell in honor of the origi- nator of the Waltham factory. Thus the "Man- chester of America" came into being. Jackson not only was the prime mover in the founding of the city of Lowell and the Merrimac Manufacturing Company, the first concern there, but he also established the Appleton Company and was interested in other local enterprises. The business at Lowell had so increased by 1830 that the problem of communication was acute. Transportation facilities by way of the Middle- sex Canal and turnpike were inadequate and Jackson turned a ready ear to the reports of steam railways which came from England. Thoroughly convinced of the practicability of a steam railroad from Boston to Lowell, he finally won his friends to the feasibility of the project, and undertook to supervise personally the con- struction. His lack of engineering knowledge led him to act with deliberation and under the best advice obtainable, but it was his own fore- sight which led the company to lay a roadbed wide enough for double tracking. On the com- pletion of the Boston & Lowell railroad Jackson looked forward to a well-earned retirement when a sudden curtailment of his fortune through real- estate speculation forced him to engage even more actively in business. The construction of the Boston & Lowell railroad had necessitated the filling in of ten acres of swamp flats upon part of which the Boston station had been built. To obtain the gravel Jackson had purchased land on Pemberton Hill and, having leveled it, built 552
