Ralph Waldo Emerson
1803–1882 · United States
The sage of Concord — essayist and lecturer who left the pulpit to preach self-reliance from the lyceum stage instead. Self-Reliance, Nature, and hundreds of lectures across decades made him America’s public philosopher of inner authority; his journals, kept for fifty-five years, were the workshop. He mentored Thoreau, championed unpopular causes, and rebuilt his thinking after every grief.
