City. Julius Kroehl thought highly of him as evidenced by his will in bequeathing many of his papers and reference books. Otto served in the U.S. Coast Survey around 1854, was active in city politics, and served as an officer of the 5th New York State Militia in 1861 for the protection of the nation's capital during its three-month mobilization. He later served as a surveyor for New York City until the end of his life. Marriage Julius married Sophia Rosa Lueber on November 25, 1858, at Holy Trinity Church of Georgetown in Washington, DC. She was born on August 27. 1832, and was a native of Frederick, Maryland. Her father, Francis Lueber (1791–1852), emigrated from Austria, and was a well-to-do merchant; her mother, Hellen Maria Simpson (1809–1890) came from the District of Columbia and was descended from the original English settlers in Maryland. Julius and Sophia had no children. After Julius' death, his widow did not remarry, but continued to live in Georgetown with her widowed mother, sisters and brother until her death on 29 September 1916, and is buried in Holy Rood Cemetery in Washington. Sophia was the niece of the American portrait artist, James Alexander Simpson, and first cousin to another portrait artist, Charles S. Hein, and his brother, Lt. Col. Otto L. Hein. She was also a distant relative of Raphael Semmes and Mary Jenkins Surratt. Records of the Mount Morris Fire Watchtower also refer to a Nina Kroehl, of unknown relation to Julius. Political activity In late 1853, the Koszta Affair had militated many Americans to form societies supporting the U.S. government's interest against the claims of the Austrian Empire. One such committee, the Society of Universal Democratic Republicanism, grew out of a movement to present Capt. Duncan Ingraham, USN, a medal for protecting Kostza in the port of Smyrna, Turkey. Many members were Forty-Eighters as well as native-born nationalists. One of the aims of the society was to monitor political situations around Europe through committees of correspondence, and note any violation of the rights of naturalized American citizens. Kroehl brought to the attention of the society that one Henry von Rensche was arrested by Prussian authorities for crimes against the Crown despite being a naturalized citizen. The Society of Universal Democratic Republicanism included Charles F. Henningsen, Hugh Forbes and Henry H. Morange as members. Engineering and New York City Kroehl listed himself as a
