Bachelder, John (07 March 1817–01 July 1906), manufacturer and inventor, was born in Weare, New Hampshire, the son of William Bachelder, a lumberman and blacksmith, and Mary Bailey. Bachelder went to public school and to college for training as a teacher. After teaching school for three years, Bachelder left New Hampshire for Boston. There he found employment as an accountant for a Middlesex Canal transportation firm. Soon he formed a partnership that competed with his former employers. The business closed upon the completion of the Manchester railroad, which eliminated the demand for shipping on the Middlesex Canal. In 1843 Bachelder married Adaline Wason; they had three children. With the demise of his transportation enterprise, he worked in Boston’s dry-goods business until 1846. During the winter of 1846, he traveled to England in an effort to establish himself as an importer. By 1847 he had established his own firm once again in a partnership called Bachelder, Burr and Company....
