Sheridan Williams watched his first total solar eclipse through smoked glass from his school playground in 1954. Since then, he has travelled the world - from Antigua to Australia, Mexico to Madagascar, Siberia to Sumatra - to see 18 total solar eclipses. Once a professional 'rocket scientist' for the UK Ministry of Defence, Williams has become a Fellow of the Royal Astronomical Society, received the British Astronomical Association's Lydia Brown medal, and served as secretary of the Open University Astronomy Club. He has written extensively about total solar eclipses, including authoring previous Bradt guides to the total solar eclipses of 2006, 2008/09, and 2012/13. He lectures widely to astronomical societies, is an astronomy-travel consultant, and guides groups to see astronomical events such as aurorae and meteor showers. He initiated education tours at the National Museum of Computing at Bletchley Park, where attractions include Colossus, the world's first programmable digital computer. He lives in Leighton Buzzard (UK).
