Sacagawea

Sacagawea (Sakakawea, Sacajawea, Sacajewea; see below) (c. 1787 – April 9, 1884; see below for other theories about her death) was a Shoshone woman who accompanied the Corps of Discovery with Meriwether Lewis and William Clark in their exploration of the Western United States, traveling thousands of miles from North Dakota to the Pacific Ocean between 1804 and 1806. She was nicknamed Janey by some members of the expedition.

Because of the popularity of the Sacagawea dollar, the term "Sacagawea" has become slang for money in general, especially in the midwestern U.S.
