Sacajawea is an Native American from the Shoshone tribe. At age 12, she was caught by a Minnetaree and after a couple of years , she was sold to a French-Canadian trader named Toussiant Charbanneau. Her husband was hired by the Lewis and Clark's expedition as a interpreter in 1804 and she decided to travel along with her first-born son, Jean Baptise or Pomp. She helped the expedition by trading goods, translating, finding edible plants and saving many of the expedition's cargo.
Toussiant Charbonneau is a French-Canadian trader. He bought Sacajawea and Otter Woman from the Minnetarees and made both women as his wife. He was soon hired by the Lewis and Clark expedition in 1804 as an interpreter and decided to bring Sacajawea along. He was the oldest of all the other people in the expedition and was mostly causing problems. Luckily Sacajawea was always there to solve them.
In 1803, William Clark received a letter from his army companion, Meriwether Lewis to join him in an expedition. He agreed to travel along and served as one of the co-leaders. He was also in charge of keeping expedition records and creating maps. After finishing his expedition, he became Native-American agent and was assigned general of the Lousiana Militia. After Sacajawea's death, he took care of her children.
Meriwether Lewis was Thomas Jefferson's personal secretary and was the captain of the Lewis and Clark expedition. He studied many plants and animals and also spoke some Native American languages. He was a highly respected captain and his journal became an important historical document in US history. After the expedition he became the governor of the Lousiana Purchase.
