The dispute between resigned Design Museum chairman James Dyson and the trustees bent on updating its mission had been running continuously for years, and contrary to the noise being made by both sides, it isn’t business: this argument is strictly personal. “The problem is not so much a question of whether the Design Museum exhibits engineering triumphs or Manolo Blahnik; it’s a battle between three exceptionally strong-minded people for the future of an institution that they all care about deeply: Dyson, Alice Rawsthorn, the director, and Terence Conran, who established the museum 20 years ago.”
