During the late 19th and early 20th centuries, the monocle was generally associated with wealthy upper-class men. Combined with a morning coat and a top hat, the monocle completed the costume of the stereotypical 1890s capitalist. Monocles were also accessories of German military officers from this period; especially from World War I and World War II. German military officers known to have worn a monocle include Hans Krebs, Werner von Fritsch, Erich Ludendorff, Walter Model, Walter von Reichenau, Dietrich von Saucken, Hans von Seeckt, and Hugo Sperrle.
