NOTE; In compiling the records of the history of the IEEE Nuclear Science Symposium my primary sources have been the IRE Transactions on Nuclear Science (1954 – 1962); the IEEE Transactions on Nuclear Science (1963 to date) and, since 1990 the Conference Record. Thanks go to the people who found copies of the old journals, especially Ralf Engels and the FZJ library, Magnus Dahlbom and the University of California Los Angeles library, Walt Hensley and the PNNL library, and Stephan Friedrich and the LLNL library. In many cases I am indebted to the diligence of past Guest Editors who faithfully recorded highlights of the meeting.
