A British manager who founded TCI in 2003. Known for owning high-quality monopolies, extreme concentration, long holding, and hard-nosed activism when needed; one of the best long-run records in the industry. A large share of profits goes to the children's charity he founded, and he's known for aggressive climate activism.
