Biography

The third Henry Gibbs (1749-1794) inevitably followed his father to Harvard. His education was financed by the pooled resources of his recently impoverished family with some additional assistance from the college and from scholarships. Henry received his degree in 1766 after a strong academic career and went on to teach school at Rowley, Newcastle, N.H., and Lynn, before returning to Salem as a merchant. A moderate Loyalist, Gibbs survived the most radical period of the Revolution with his affairs intact and married Mercy Prescott in 1781. Henry died in 1794, Mercy in 1809, leaving a legacy of children to Yale College, rather than Harvard. (1)
