Sheridan Williams is a Fellow of the Royal Astronomical Society, recipient of the British Astronomical Association’s Lydia Brown medal, secretary of the Open University Astronomy Club and former professional ‘rocket scientist’ for the UK Ministry of Defence. He watched his first total solar eclipse through smoked glass from his school playground in 1954. Since then, Williams has travelled the world – from Antigua to Australia, Mexico to Madagascar, Siberia to Sumatra – to see 18 total solar eclipses. 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.
