ACKNOWLEDGMENTS
My first thanks must go to Mike McCabe of Salisbury, Connecticut, who in 1995 sold me my first book from the Science and Civilisation in China series. It was a secondhand copy of Volume IV, Part 3, Civil Engineering and Nautics; and the fact that his Lion’s Head Books—a store now long defunct and still greatly missed—had the book in stock and priced very nearly affordably allowed me to snap it up on impulse, to read it outside in the store’s parking lot, and to be rendered instantly enthralled by the sweep and scope of the mind behind it—the extraordinary mind of Joseph Needham.
The Needham Research Institute in Cambridge—where the ashes of Joseph, Dophi, and Gwei-djen, now commingled by time, lie beneath a tree in the gardens—is the present-day keeper of the flame, and I owe the very greatest of thanks to its director, Professor Christopher Cullen, who made me most welcome and allowed me full access to all those papers and artifacts that did not happen to be held in the immense collection of Needham documents across Grange Road in the Cambridge University Library. John Moffett, the NRI’s librarian, was also tirelessly helpful; both he and Dr. Cullen read the first draft of the typescript and each made many valuable suggestions. I hope that what appears now meets with their approval; should any errors of fact or judgment either remain or have crept in, they are my responsibility alone.
I wish to record my thanks also to the institute’s longtime administrator, Sue Bennett, as well as to archivist Joanne Meek; former director Ho Peng Yoke; and Sir Geoffrey Lloyd, scholar-in-residence and onetime chairman of the East Asian History of Science Trust, which generally oversees the institute. Lady Pamela Youde, who is the widow of the fondly remembered governor of Hong Kong, Sir Edward Youde, and who succeeded Sir Geoffrey as chairman of the trustees, was also extremely supportive.
At Caius College, Cambridge, I wish to record my thanks to the Master—and former British ambassador to China—Sir Christopher Hum; to Yao Ling, the college president; to Iain Macpherson, a fellow of Caius, a longtime friend of Needham’s and executor of his estate; the distinguished fellows Mikulas Teich, Anthony Edwards, John Robson, and Jimmy Altham; the historian and archivist Christopher Brooke; and the college librarian Mark Statham. While I worked in Cambridge, the Master of Darwin College, Professor William Brown, placed rooms, as well as dining and research facilities, at my disposal, for which I am most grateful.
I should like to thank the unfailingly helpful staff of the Documents Room at the University Library, Cambridge; I was also ably assisted here by Helen Scales, a marine scientist and expert on seahorses, who took time out from her own work and very kindly sought out some much-needed Needham papers for me; and by my son Rupert, who helped as he so often does with my book projects, in this case by sedulously transcribing scores of pages from Needham’s China diaries.
Staff at the China offices of the British Council were perhaps naturally predisposed to help a visitor who was researching the life and work of their most distinguished predecessor, who happened to be first-ever council officer based in the Middle Kingdom: So I was assisted generally by Michael O’Sullivan and Robin Rickard in the Beijing headquarters, and later and more especially, by David Foster and his delightful wife, Connie Lau, in Chongqing. The British cons
ul-general at Chongqing, Tim Summers, together with his wife, Lucy Chan, proved the most hospitable of guides. Peter Bloor in the council’s London offices also looked up some valuable archival material for me.
