Physician. Southey’s younger brother. With the help of his uncle Herbert Hill, Southey provided money for Henry Herbert’s education at Norwich and Edinburgh. His concerns about his younger brother’s lack of application proved — eventually — to be ill-founded, and in later life the two enjoyed a close friendship. Henry graduated MD on 24 June 1806, producing, with Southey’s help, a dissertation on the origins and course of syphilis which suggested an American origin for the disease. Southey also helped Henry’s finances by procuring him reviewing work in the Annual Review. Henry travelled to Portugal in 1807, returning before its conquest by France at end of the year. He married Mary Sealy (1784–1811), the daughter of a wealthy Lisbon merchant, in 1809. In 1815 he married for a second time, his bride being Louisa Gonne. In his later years Henry became a successful London doctor, with premises in Harley Street and an appointment as physician in ordinary to King George IV.
