I once had a heated discussion with a classical violinist about who the most known Dane was outside of Denmark. She insisted that it had to be Carl Nielsen, a composer, whom she was sure everyone would know. All her friends knew Carl Nielsen, and many of them could play his most known symphonies from memory.<p>I'd only vaguely heard of him, and contended that maybe Hans Christian Andersen would be more known, since Disney had adopted his fairy tales and made them into stories that every child around the world would know. Or maybe Niels Bohr, since his contributions to atomic science were so great.<p>She would have none of it, and insisted that everyone she talked to, both in Denmark and abroad would instantly recognise Carl Nielsen, but only some would recognise Bohr, and a few didn't really know Hans Christian Andersen, and certainly didn't know all his stories by heart like they knew Carl Nielsens symphonies.<p>She lived in a bubble: Her friends and the people she worked with were all musicians, composers, or were otherwise deeply into classical music, so she made the obvious mistake of thinking that Carl Nielsen would be widely known, since everyone she met seemed to know him and his music well.<p>If you asked people on HN who the most famous Dane is David Heinemmeir Hansson might be mentioned. Or maybe Bjarne Stroustrup who invented C++, or Rasmus Lerdorrf who invented PHP, or maybe Anders Hejlsberg who invented turbo pascal, Delphi and C#, or Lars Bak who developled the Chrome V8 javascript engine and was developer lead on Googles Dart language.<p>You need to look beyond your own bubble to see who is notable in the general public. Ask a random stranger on the street how many pornstars he can name, and then how many scientists he can name and you'll see that the author lives in a bubble.
