Related documents: [0]  [DOC] Iron Tail (Oglala Lakota: "Siŋté Máza" in Standard Lakota Orthography) (1842-May 29, 1916) was an Oglala Lakota Chief and a star performer with Buffalo Bill’s Wild West. Iron Tail was one of the most famous Native American celebrities of the late 19th and early 20th centuries and a popular subject for professional photographers who circulated his image across the continents. Iron Tail is notable in American history for his distinctive profile on the Buffalo nickel or Indian Head nickel of 1913 to 1938. [END] 
[1]  [DOC] Dewey Beard or Wasú Máza ("Iron Hail", 1858–1955) was a Minneconjou Lakota who fought in the Battle of Little Bighorn as a teenager. After George Armstrong Custer's defeat, Wasu Maza followed Sitting Bull into exile in Canada and then back to South Dakota where he lived on the Cheyenne River Indian Reservation. Chief Iron Hail is often mistaken by historians for Chief Iron Tail, being Lakota contemporaries with similar-sounding names. Most biographies incorrectly report that Chief Iron Tail fought in the Battle of the Little Bighorn and that his family was killed in 1890 at Wounded Knee, when in truth it was Chief Iron Hail who suffered the loss.
