Edward de Bono, polymath, writer, and philosopher, spent his life showing people how to use their brains creatively, to disrupt traditional ideas and ways of doing things. He mixed socially with powerful people, but he never stopped challenging their limited beliefs. He travelled the globe, bringing his lateral thinking techniques to schools, corporations, and leaders in crisis. Adored by advertising agencies, misunderstood by the media, and mistrusted by academia, De Bono became a household name dominating the field of creative thinking for half a century. With contributions from de Bono's family, friends and colleagues and Sir Tony Blair.
