Ambrose, like many biographers before him, is a man enamored of his subject. To him, Meriwether Lewis is the paramount, curious, bootstrapped Renaissance man of the early 19th century; this bosom buddy of Thomas Jefferson is the bold Yin to William Clark’s relevant but slightly duller Yang. His biographic sweep of Lewis primarily concerns the exhilarating rawness of the journey of the Corps of Discovery during 1804-1806, but it is at its core a story about the man, not merely the events for which he is yet championed.

I’ve always been envious of people who can memorize poetry. Or prose passages, quotes, strings of digits. I’m tolerable good at minute fact-based recall—hence the appeal of little historical anecdotes, dates, foreign languages, minerals, functions in programming languages—but I’m hopeless with literature or poems. Or so I thought.
