"Secret Heroes: Everyday Americans Who Shaped Our World," by Paul Martin, is a remarkable collection of stories that spotlight 30 unknown champions, explorers, inventors, and innovators who were forgotten in the pages of American history textbooks.

Instead of George Washington, we learn about the tailor who saved his life…twice.

The overlooked Americans in Secret Heroes all had an impact on their world (and the modern world), says the author, former Executive Editor of National Geographic Traveler. The illuminating stories include:

Some other characters Martin brings to life include Henry Beachell, whose invention of "miracle rice" fed and supported Asia; Cynthia Ann Parker's steadfast endurance of 24 years of Native American captivity and Jonathan Letterman, whose medical organization on the battlefield revolutionized the treatment of wounded soldiers and saved countless lives during the Civil War.
