You might know Katharine Lee Bates wrote the poem that eventually became the song, “America the Beautiful,” after she visited the top of Pike’s Peak in Colorado and was overcome by its beauty.

But did you know she grew up a precocious youngest child in a family that struggled after the death of her father? And that she was a budding feminist who chafed at menial tasks like sewing and wished for nothing more than to be a scholar? And did you know she was only ever paid $5 for the song that would become America’s unofficial national anthem?

It’s another example of an ordinary person whose contributions to our country’s legacy are extraordinary.

That’s a class of people government teacher Sharon McMahon finds especially compelling. In her new book, “The Small and Mighty,” she highlights unsung Americans who changed history but didn’t make it into the textbooks (often, “because they weren’t a white man,” she reminds her readers).

It’s a take fans of her podcast, “Here’s Where It Gets Interesting,” will find familiar. A former government and law teacher, McMahon lives in Duluth. But she burst onto the national stage in 2020 when she took to Instagram to combat misinformation she saw swirling on social media after the election. Her direct yet amiable style garnered her account, @sharonsaysso, more than a million followers, who now look to her for historical and current event facts and context.

This week on Big Books and Bold Ideas, McMahon joins host Kerri Miller to talk about “The Small and the Mighty,” why history matters more than ever, and how her belief in everyday Americans influencing democracy animates all her work.
