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).
Heinrich Jacob Goldschmidt
Heinrich Jacob Goldschmidt, also Heinrich Jakob Goldschmidt (12 April 1857, in Prague, Austria-Hungary – 20 September 1937, in Oslo, Norway), was a Jewish Austrian chemist who spent most of his career working in Norway. He studied chemistry at the Charles University in Prague, where he received his PhD in 1881. In the same year, he became professor at the ETH Zurich, where he worked with Victor Meyer. In 1888, his son Victor Goldschmidt was born; Victor later became a renowned mineralogist and founder of modern geochemistry. After working at the University of Amsterdam with Jacobus Henricus van 't Hoff in 1894 and 1895, Heinrich Goldschmidt became full professor at the ETH. He left the ETH in 1901 for the University of Oslo. He worked there until his retirement in 1929 at the age of 72. As his son Victor became professor for mineralogy at the University of Göttingen in 1929, he moved with him to Göttingen, but both had to leave there after the Nazis came to power, and father and son returned to Oslo in 1935. Heinrich Jacob Goldschmidt died in Oslo in 1937.
