Game-Changers: we pick our top 20 creative world-rockers

In 20 remarkable years we have come across, written about, examined and exhumed a lot of remarkable people. On the following profiles are 20 of them. This, though, is not a simple ranking of power and influence. These are stories that resonate, with which we find common purpose and cause. Here are people who have sometimes stuck bloody-mindedly to a course, sometimes pivoted, re-examined and pushed in new directions, who have defied expectations and even open derision. They have shown courage under fire and grace under pressure. They have transformed – from girl group popette to one of the fashion industry's smartest operators, for instance – and, over the last 20 years, have had a transformative influence in their field. Here are architects who build with a sense of the immaterial, artists who want to talk to everyone, experimentalists and food engineers, fashion designers who defy fashion and bob and weave like prize fighters, tech titans who have changed the way we do almost everything. One reinvented the hotel industry, another presents it with an existential threat. There is also a man who wants to save the world – or take us all to Mars if that doesn't work out. Either way, we'll be along for the ride.
