Arnold Dulon (1843 - August 14, 1929) was a city surveyor and topographical draftsman in the service of the city of New York in the late 19th and early 20th centuries. Dulon was born in Germany and, fleeing the unrest associated with the Revolutions of 1848, emigrated to the United States, arriving in Ellis Island on September 30, 1853. Dulon served in the Union army during the American Civil War from 1862 to 1863. Following the war, he was in the employ of the city of New York for more than 20 years: 1872 - 1875 Registrar's Office, 1894 - 1897 Commissioner of Street Improvements, 1898 - 1901 Board of Public Improvements, 1902 - 1915 Topographical Draftsman for the Bronx. He applied for retirement in 1915, citing that at his advanced age, 73, he was physically incapable of performing his duties. After retiring Dulon moved to California, living in Solano from 1918 until 1928.
