The Anneke family originates from a small village called Schadeleben close to Quedlinburg in what is today Saxony-Anhalt. Schadeleben is close to the Harz mountains, one of the oldest mining regions in Europe. Like the family of Martin Luther, whose birthplace, Eisleben, is only a few kilometers away from Schadeleben, many of Anneke's ancestors had worked in mining, which is why the family moved to Dortmund in the early 19th century, when industrial coal mining was beginning in the Ruhr district. Like his father, Anneke's brother Emil was a mining inspector, before he became involved in the 1848 revolution. Anneke became a Prussian artillery officer, but was dishonorably dismissed in 1846 because of his democratic activities at his garrison in Münster, and also because he refused a duel. While still in Münster he met the divorced Mathilde Franziska von Tabuillot, who later became his wife. He was one of the leading figures of the Communist movement in Cologne, together with his friends Karl Marx, Friedrich Engels, and Moses Hess. He spent most of 1848 in jail for his political activities. In 1849 he joined the revolutionary campaigns in the Palatinate and Baden, and was commander of the artillery there. Carl Schurz served as his adjunct officer. After the fall of Rastatt he fled to France, where he found refuge with his wife in the house of their mutual friend Moses Hess. Later on he worked as a correspondent for U.S. media in Europe, where he tried to join the Italian revolutionary movement under Giuseppe Garibaldi. In 1862 he returned to the USA to assume command of the 34th Wisconsin Volunteer Infantry Regiment as a colonel. In 1863 he became the victim of blackmail and was dishonorably dismissed. His regiment was dissolved on September 9, 1863. Afterwards he tried in vain to be readmitted to Army service, supported by his brother Emil Anneke, who was a leading Republican in Michigan and acting Michigan Auditor General. Many of Anneke's friends and comrades from the 1849 campaign in Germany had become Union generals, including his own junior adjunct officer Carl Schurz, August Willich, Ludwig Blenker, Franz Sigel, and Gustav Struve. After various failed commercial enterprises and the split with his wife Mathilde, Fritz moved to Chicago, where he died on Sunday night 8. December 1872, after an accident. The short-sighted Anneke had fallen into a construction pit. Lighting was very bad in Chicago in those days, and the city was, one year after the Great Chicago Fire, full of such pits. A son of Fritz, Percy Shelley Anneke, was a local celebrity in Duluth, Minnesota, as co-founder and owner of the famous Fitger Brewing Company, which is now registered as a U.S. National Historic Place.
