James Baker (1739-1825), son of James Baker (1713-1776) and Priscilla Paul Baker (1718?-1776), graduated from Harvard College in 1760. After teaching school, studying theology, and serving an apprenticeship to a physician, Baker opened an apothecary shop in Dorchester, Mass., which expanded into a general store. In 1769 he married Lydia Bowman ( -1816), daughter of Rev. Jonathan Bowman (1703-1775) of Dorchester. They had three children: Edmund (1770-1846); Elizabeth (1774-1805); and Lydia (1777-1851).
Having helped Daniel Vose establish a chocolate manufacturing business in 1772, Baker took on Nathaniel Blake shortly before Vose withdrew from the business in 1780. Baker then closed his general store and devoted all his attention to making Baker's Chocolate. Dr. Baker retired from the business in 1804, leaving it entirely in the hand of his son, Edmund. The business had been prosperous, but was destined to achieve national prominence under guidance of Dr. Baker's grandson, Walter Baker (1792-1852).
