Jacob Westervelt (sheriff)
Jacob Westervelt (1794–1881) is often confused with his brother-in-law John Jacob V.B. Westervelt (1805–1866), who was a Deputy Sheriff under him, and subsequently High Sheriff of New York City himself too (1846–1849), as well as Assistant Alderman from the 16th Ward (1844–1846). Another namesake is Jacob Aaron Westervelt (1800–1879), the shipbuilder, Alderman from the 13th Ward and later Mayor of New York City (1853–1855).
Jacob Burckhardt
Carl Jacob Christoph Burckhardt (May 25, 1818 – August 8, 1897) was a Swiss historian of art and culture and an influential figure in the historiography of both fields. He is known as one of the major progenitors of cultural history. Sigfried Giedion described Burckhardt's achievement in the following terms: "The great discoverer of the age of the Renaissance, he first showed how a period should be treated in its entirety, with regard not only for its painting, sculpture and architecture, but for the social institutions of its daily life as well." Burckhardt's best known work is "The Civilization of the Renaissance in Italy" (1860).
