I am a specialist speaker, guide and writer on the colourful 400+ year history of science, technology, engineering and medicine.

My talks are aimed at anyone with an enquiring mind. The history of science and technology is sometimes neglected despite its compelling richness, curious characters, global significance and unexpected twists and turns. I pride myself on offering entertaining talks whether my audience is scientifically minded or not. I like to bring my talks to life with the words of participants or eye witnesses to events.

I started out lecturing with London subjects particularly in mind, but my researches into engineering history encompass western Europe.

I have given talks for the Newcomen Society, London Historians, at the RSA and Geological Society of London, Salon for the City, Women's Institute, City of London Historical Society, U3A, Probus, Westbury Festival, and the University of North Carolina in London. I have led tours based on my researches for individuals, school, corporate and university groups.

I don’t speak for them but I've been a long-time volunteer in the archive at the Royal Institution of Great Britain (founded 1799) for which I have also written numerous blogs - and also at the archives of the Royal Society for the Encouragement of Arts, Manufactures and Commerce (founded 1754) which was once a significant force in the advancement of technology or 'practical arts.'

I spend much of my time researching curious things that I think you will find interesting too. So, if it's technological and historical, there is a very good chance that I can talk about it! Please do contact me to discuss the possibilities. The talks listed last an hour, but I have some shorter ones available. (By clicking on any of my talks you will be able to send a message to me.)
