The Dozys, like other contemporary French families, emigrated to the Low Countries after the revocation of the
edict of Nantes, but some of the former appear to have settled in the
Netherlands as early as 1647. Dozy studied at the
University of Leiden, obtained the degree of doctor in 1844, was appointed an extraordinary professor of history in 1850, and professor in 1857. Dozy was a correspondent of the Royal Institute between 1848 and 1851. He became a member of the successor institute, the
Royal Netherlands Academy of Arts and Sciences, in 1855.
