64 - Baroness Beeban Kidron

Baroness Beeban Kidron is the filmmaker turned internet safety activist, whose time in the silver screen boasts directorial credits on Bridget Jones: The Edge of Reason and Oranges Are Not The Only Fruit. Her latest mission, described as "one middle-aged woman's campaign against Silicon Valley", has influenced tech policy on both sides of the Atlantic - and last week, California introduced its own online safety bill based on her work in the House of Lords.
