I heard Trevor Marchant give this talk at a conference last year and it is fantastic in that it shows a serious academic with a genuine understanding and reverence for the skills involved in traditional crafts and how they are passed on from generation to generation in traditional cultures. I am delighted to discover that Trevor has been elevated to the position of professor and his inaugural lecture is now online. If you want to skip the intro his talk starts at 15 mins in. It is longer than most stuff I post here but I think his work is very important for traditional craftspeople. It’s a shame you can’t see the fantastic pictures of buildings that accompany the talk but the words are worth listening to.
