- Existence: 1864-19--
August Sinning was born in Spangenberg in Germany on April 19, 1864 to a well-to-do soap maker and merchant. About the age of sixteen, Sinning and a friend came to America. After staying with a relative of the friend on the east coast, they came to Muscatine, Iowa. Sinning spent a year in Muscatine, working at various jobs before he moved to Nebraska, and then to Marengo, Iowa, and then back to Muscatine. He worked at a greenhouse during the day and attended night school. He read science and medical books in his spare time.
In 1891 he started Liberal Arts courses at the University of Iowa, and in 1892 he entered the medical college. During his years at the University, he taught German to ex-President Macbride's children in return for room and board. He graduated from the Medical School in spring 1895 and moved back to Muscatine to become an associate in the office of Dr. Fulliam. In September 1895 he married Katherine Kranz, the daughter of the family who owned the greenhouse where he had worked earlier. After their marriage, they moved to Germany, where Dr. Sinning attended the University of Berlin from 1895-1896. They returned to the United States in 1897, and Dr. Sinning practiced medicine at several locations in Iowa, including New Liberty, Bennet, Ackley, and finally, Iowa City. For a time he was the surgeon for the Chicago and Rock Island Railroad. In 1910, he went into practice by himself in Iowa City, where he practiced until he retired.
