10. George Washington Carver
George Washington Carver revolutionized agriculture by promoting crop rotation and introducing innovative uses for peanuts and sweet potatoes. Unlike many contemporaries focused solely on cotton, Carver encouraged farmers to diversify crops, restoring nutrients to depleted soil and improving yields. His research and advocacy helped usher in more sustainable farming practices across the South. The USDA credits Carver with transforming American agriculture and laying the groundwork for modern environmental stewardship.
