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. Early life and family Siŋté Máza was the Chief's tribal name. Asked why the white people call him Iron Tail, he said that when he was a baby his mother saw a band of warriors chasing a herd of buffalo, in one of their periodic grand hunts, their tails standing upright as if shafts of steel, and she thereafter called his name Siŋté Máza as something new and novel. Iron Tail and Iron Hail Chief Iron Tail is often mistaken by historians for Chief Iron Hail ("Dewey Beard"), being Lakota contemporaries with similar sounding names. Most biographies incorrectly report that 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 Iron Hail who suffered the loss. Major Israel McCreight reported: "Iron Tail was not a war chief and no remarkable record as a fighter. He was not a medicine man or conjuror, but a wise counselor and diplomat, always dignified, quiet and never given to boasting. He seldom made a speech and cared nothing for gaudy regalia, very much like the famed War Chief Crazy Horse. In this respect he always had a smile and was fond of children, horses and friends." Iron Tail and Buffalo Bill Iron Tail was an international personality and appeared as the lead with Buffalo Bill at the Champs-Élysées in Paris, France, and the Colosseum in Rome, Italy. In France, as in England, Buffalo Bill and Iron Tail were feted by the aristocracy. Iron Tail was one of Buffalo Bill's best friends and they hunted elk and bighorn together on annual trips. On one of his visits to The Wigwam of Major Israel McCreight, Buffalo Bill asked Iron Tail to illustrate in pantomime how he played and won a game of poker with US army officials during a Treaty Council in the old days.
