Following completion of his natural science degree at Cambridge specialising in the history and Philosophy of Science, Nick Kollerstrom worked for the Medical Research Council’s Air Pollution Unit. This resulted in his first book Lead on the Brain, an investigation into lead pollution from petrol, and this was promoted by the Green Party to raise awareness. While living in Guildford, he worked as a secondary school maths teacher for five years. He worked in the local Green Party and it was very successful; in 1989 they secured 22% of the vote for West Surrey Green Party in the Euro-election. His PhD was on Newton's lunar theory, after which he was a Research Fellow at UCL. He was invited to compose the biography of Newton for the prestigious Biographical Encyclopaedia of Astronomers of 2007. His various history of astronomy articles are online at dioi.org/kn/ and he's a Fellow of the Royal Astronomical Society. He has authored many books exploring a wide variety of subjects, including The Unnecessary War (1988), Newton’s Forgotten Lunar Theory (2000) Crop Circles, the Hidden Form (2002), Terror on the Tube (2009), and Venus, the Path of Beauty (2017).
