Etymology
Keiser is a spelling variant of German Kaiser, from Middle High German and earlier forms meaning “emperor.” The word ultimately comes from Latin Caesar, the Roman imperial title that became a general term for a ruler. As a surname, it likely began as a nickname, an occupational-style title name, or occasionally a house-name for someone associated with authority or imperial symbolism.
