About George Dyson
From his TED bio page:
A member of the fabulous Dyson clan, George Dyson is sometimes defined as a son-of and a brother-of, but he has found his own voice as a chronicler and a philosopher of science and the future. The son of physicist Freeman Dyson, George grew up inside one of the most fervid hotbeds of scientific research in the Atomic Age. He spent his early adulthood living in a treehouse, and designing and building Aleutian kayaks (chronicled in his book Baidarka: The Kayak). While he maintains his kayak business now, his parallel interest in science and the future has brought him to the fore.
