Simon J. Schaffer is a professor of the history and philosophy of science at the Department of History and Philosophy of Science at University of Cambridge and was until recently editor of The British Journal for the History of Science. After completing his BA at Trinity College, Cambridge, Schaffer went to Harvard University as a Kennedy Scholar, and has taught at Imperial College London and the University of California, Los Angeles. Schaffer has been a Fellow of Darwin College, Cambridge since 1985. Schaffer has authored or co-authored numerous books, including Leviathan and the Air-Pump: Hobbes, Boyle, and the Experimental Life with Steven Shapin. In addition to his work at Cambridge, he has been a presenter on the BBC, in particular the series Light Fantastic broadcast on BBC Four in 2004. In 2005 he shared the prestigious Erasmus Prize with Steven Shapin for Leviathan and the Air-Pump. This Dutch prize was handed over by the Dutch crown prince Willem-Alexander and can be regarded as a token of appreciation for the intrinsic value of his work for the history of science in general. In 2013 he received the Sarton Medal, the most prestigious honor awarded by the History of Science Society, in recognition of his “lifetime of scholarly achievement”.
