Sacagawea endured personal hardships during the expedition

Sacagawea’s skills and presence were vital to the expedition’s success

The group hired French-Canadian trader Toussaint Charbonneau and his wife Sacagawea to serve as translators. Sacagawea became invaluable to the Corps, as she could speak Shoshone and had a familiarity with the geography of the region. Acting as interpreter and cultural bridge, Sacagawea helped secure Shoshone horses, identified key landmarks, and signaled peaceful intent to other tribes.

The Lewis and Clark Expedition unexpectedly ran into Sacagawea's long-lost family in the Rocky Mountains.

Sacagawea's son, Jean Baptiste, who was born during the Lewis and Clark expedition, traveled to Europe as a duke's companion before returning to the American West.

Squanto was a tragic character in the original Thanksgiving story

Tisquantum (also known as Squanto) played a crucial role in the survival of the Pilgrims. As an English speaker, Squanto assisted the Pilgrims in gathering food and communicating with other Native peoples. However, his story also involved being sold into slavery by an English sea captain and returning home to find his tribe decimated by disease during the Great Dying. Tisquantum met his end not long after that first Thanksgiving, with historians speculating he died either by disease or assassination.

How Cassatt's early life influenced her art

The painter came from an affluent background but was determined to become an artist, a decision that was at odds with her father's wishes.

Jefferson omitted a plan to go beyond the Louisiana Territory in his funding request

In January of 1803, the president sought $2,500 to fund the expedition (though it likely cost closer to $50,000). The ostensible rationale for the journey was to explore the newly purchased territory, but Jefferson did not mention he wanted Lewis and Clark to go beyond the newly acquired territory for several reasons.

Cassatt painted more than just mothers and daughters

In one 1884 portrait, she captured her brother, Alexander Cassatt, and her nephew during a family holiday. The image is just as tender as her paintings of mothers and daughters, with the father and son—their faces near mirror images—in an intimate embrace.

Scholars note that many Cassatt paintings are about women's labor

The women in her portraits are often performing domestic work, something that contemporary scholars consider a subtle protest of how women's labor was often overlooked during Cassatt's time. Fittingly, Cassatt often hired working-class women as models, ensuring the portraits were not only accurate but that the subjects were appropriately compensated.

Sartre spent his time in the French Army working on a novel

The writer's physical limitations (including partial blindness and balance issues) prohibited him from serving on the front lines. Instead, he worked as a military meteorologist. The job was not very demanding, so he spent most of his time writing. He told Simone de Beauvoir it was "extremely peaceful work; indeed I cannot think of any branch of the services that has a quieter, more poetic job."

One of Sartre and de Beauvoir's lovers accused them of exploitation

The philosophical duo's open relationship sometimes included shared partners, including de Beauvoir's students. One of those students, Bianca Lamblin, wrote a book, "A Disgraceful Affair," about the experience and characterized it as sexual exploitation.
