ST. LOUIS-The latest U.S. coin is carved with the likeness of someone who furthered his education right here at Saint Louis University.

On Sunday, the U.S. Mint releases a dollar coin featuring an image of Sacagawea, a teenage Native American guide who helped to lead the Lewis and Clark expedition, and her infant son, Jean Baptiste Charbonneau, who attended Saint Louis University during the early 1820s.

Jean Baptiste led a fascinating life. :

• He was born during the expedition (Feb. 11, 1805) and was carried by his mother on her back through all types of weather and terrain, which is depicted on the new coin.
• Following his education at Saint Louis Academy, the forerunner to Saint Louis University, Jean Baptiste returned to Europe with a German prince, where he received further education and served as a spy of sorts for his adopted father, William Clark.
• William Clark, who spent almost his entire post-expedition life in St. Louis, made sure that Jean Baptiste received an education at Saint Louis Academy, the oldest and, at the time, the only school west of the Mississippi. Jean Baptiste's father was Touissant Charbonneau, the famous translator for the expedition.

Founded in 1818, Saint Louis University is the second oldest Jesuit university in the country. Saint Louis University is one of only three Catholic universities in the United States to receive the Carnegie Foundation's Research II classification and has been heralded as a character-building college by The Templeton Guide: Colleges That Encourage Character Development.
