Otto is a masculine German given name and a surname. It originates as an Old High German short form of Germanic names beginning in "od" or "ot," meaning "wealth, property". Due to Otto von Bismarck, the given name Otto was strongly associated with the German Empire in the later 19th century. It was comparatively frequently given in the United States (presumably in German American families) during the 1880s to 1890s, remaining in the top 100 most popular masculine given names in the US throughout 1880–1898, but its popularity decreased significantly after 1900 with increasing anti-German sentiment leading up to World War I. Some famous people named Otto include Otto von Bismarck, Otto III and Otto IV, Holy Roman Emperors, and Otto of Greece.
