My father, André Starck, was an aircraft designer but he invented a lot of other things too. People are still using many of his inventions – things like lipstick tubes or non-slip coating. He invented loads of stuff but didn't file patents."I have often criticised people who take over the parent's business. But ultimately, even in my case it went more or less unnoticed. I did the same thing which is a bit sad, a step backwards. Nor am I exaggerating. It's infinitely more difficult to build a plane and get it to fly than to invent a chair and sit on it. In the normal course of things children should feel duty bound to do better than their parents. Not only did I invent nothing new, I even carried on with the same stock-in-trade and instead of staying in aviation, which would have taken me into higher spheres, I came down to earth to do easy things. It was not an easy way out, but I made easy things.
