Who you will be writing to
At twenty-two, Charles Darwin boarded the Beagle for a voyage around the world that lasted five years. He spent most of the rest of his life at a quiet house in Kent, patiently studying barnacles, orchids, pigeons, and earthworms, and thinking through the idea that became On the Origin of Species.
He was one of the great letter writers, exchanging thousands of letters with gardeners, breeders, and naturalists everywhere. Questions were how he worked, and he will have plenty for you.
What the letters hold
- The small dramas of a garden or hedgerow
- Slow change, and what patience uncovers
- Collecting, sorting, and wondering
- Dogs, family life, and the comforts of routine

Is each letter written by a person or by AI? A bit of both, and we're glad to be clear about it. Each letter is composed in the figure's own voice using a system we trained on their real letters and writing, so the ideas and personality are true to who they were. Then a real person reviews and refines every letter before it goes out. The result is original and personal, never pulled off a shelf.
