He is a former Visiting Professor of Computing Mathematics at Gresham College. As a former undergraduate at Pembroke College Cambridge, with which Burnside was closely connected, Tony is pleased to have edited, with Peter M. Neumann and Julia Tompson, The Collected Papers of William Burnside (Oxford University Press, 2004). Mary Croarken Mary Croarken started her academic career at the University of Warwick with a degree in Computer Science and then a PhD in History of Computing. Mary has subsequently held a series of academic fellowships including the Sackler Fellowship at the Centre for Maritime Research at the National Maritime Museum (NMM) 2000 – 2002. While at NMM, she helped to organise a joint NMM and British Society for the History of Mathematics conference called Greenwich: Some Mathematical Connections which provided the inspiration for this book. Mary continues her academic interests in human computers but now works full time supporting health research in the NHS.
