Firebrand conservative columnist, commentator, Internet entrepreneur, and #1 New York Times bestselling author Michelle Malkin tells the fascinating, little-known stories of the inventors who have contributed to American exceptionalism and technological progress.

Call them America’s “tinkerpreneurs”—unsung innovators who commercialized their “little” ideas to create products, companies, wealth, and opportunities that thrive today. Tireless, self-made, and largely self-taught, they raised our standard of living with the creation of items we daily take for granted, from razors to bottle caps, flashlights to bridge cables.

This entertaining and enlightening treasury is, in part, Michelle Malkin’s response to President Obama’s infamous assertion that “if you’ve got a business, you didn’t build that.” She examines how factors such as profit motive, intellectual property rights, patriotism, faith, family, and an unwavering belief in American exceptionalism set the stage for the creation of toilet paper, glass bottles, the hydroelectric power plant, and more.

Demonized by the left as greedy villains and selfish barons, these visionaries have nurtured job-creating powerhouses used today by “progressive” propagandists who can’t comprehend how much comfort and convenience they enjoy as a result of the ingenious contributions by these original American dreamers. Are they rich? You bet. They earned their private rewards for the public good. Find out Who Built That—and the next time you turn on your air conditioner, say thank you.
