Henry James was William James’s brother and close friend, Emerson his godfather. He went up the Amazon to collect zoological specimens with Agassiz, and studied with Helmholtz. Wright and Peirce (a lifelong friend) were close Harvard colleagues; Santayana, Du Bois, Sidis and Stein were among his students. He met Russell in England, Bergson and Charcot in France, and Freud on his only U.S. visit. Meeting Wundt (his fellow-founder of experimental psychology) in Germany, they thought little of each other. Wells drove up just after he’d been found up a ladder by his brother, spying on his colleague Chesterton.
