From Parker’s History of Nashua-
JOSEPHUS BALDWIN, the first mayor of the city, was born in the south part of Nashua in 1803. His father lived on the Highland Farms, and possessed unusual mechanical and inventive ability. The son gave his attention to the improvement of cotton machinery. His first experiment was at New Ipswich in making shuttles and spools to supply the few cotton-mills then running in New Hampshire. After the building of the mills at Nashua he returned and began the making of bobbins and shuttles at the Highland Farm. In 1836 his works, including a large stock just finished for the market, was burned. Without means, he began work in a room of the machine-shop of the Nashua Manufacturing Company. Here his works were burned out a second time. But in 1843 he demand for that kind of furnishing which Mr. Baldwin, of all others, was best able to supply, became so great that, starting his business on Water Street, he soon built up an extensive manufactory, employing one hundred and ninety hands. For fifteen years Mr. Baldwin was the largest manufacturer of bobbins and shuttles in this country. Like many enterprising and ingenious men, he gave no attention to financial details, and allowed the free use of his name to friends, so that he became embarrassed in 1858, and the business, built up by him, passed into the hands of Dr. F.B. Ayer and Isaac Eaton, by whom it has been continued until recently. Mr. Baldwin died in 1872.
