Biographical note
When I used to give chemistry lessons to friends some 50 years ago, I would bring with me a pocket-full of chemicals to illustrate the principles of chemistry. Today, these chemistry lessons have evolved into demonstration lectures which I give to audiences in a wide variety of locations. During the past 40 years I have given over 500 talks, in addition to teaching chemistry full-time at Highgate School in London. Today this continues to be the base for all my talks.
The Royal Society of Chemistry has included me on their "175 Faces of Chemistry"
