経歴と著者の歩み

David Giles Lewis is a British leadership writer, consultant, and executive educator whose public biographies emphasize professional formation more than private early-life detail. What is documented is a mixed education in study and practice: public profile information lists Brunel University of London among his formal studies, while later biographies describe a career built across more than 35 years in business, consulting, entrepreneurship, and academia. Before becoming widely known as an author, he held senior roles as a managing director and head of department, grew and sold ventures in consulting and software, and developed a reputation for helping senior teams work through uncertainty. A major turning point came with his long association with London Business School, where he led executive programmes on senior leadership and strategy execution and increasingly translated classroom ideas into public thought leadership.
