Episode Details

Cyrus McCormick is credited with inventing the mechanical reaper that revolutionized American agriculture — but the real story is messier. His father built the first prototype, a slave named Jo Anderson may have contributed critical design elements, and McCormick's genius lay less in invention than in marketing, patent litigation, and the ruthless business tactics that built an agricultural machinery empire.

This episode examines the gap between the McCormick invention myth and the documented reality, tracing the reaper's actual origins, the patent wars, and the business empire that made McCormick one of the wealthiest men in Gilded Age America.

• The father's original prototype and the disputed contributions of enslaved worker Jo Anderson
• McCormick's marketing innovations — field demonstrations, credit sales, money-back guarantees
• The patent wars and the legal battles that were as important as the technology itself
• The International Harvester empire and the transformation of American agriculture
