An autobiographical memoir, illustrated with photographs. The first 8 of 16 chapters contain information on Taylor's professional life. Chapter 2 is entitled "The Process Called Education (1902-1930)" and consists of a very entertaining account of Taylor's early and advanced education with numerous anecdotes. This is followed by a discussion of Taylor's years at the National Bureau of Standards (1927-1964), describing in great detail his scientific, social, and institutional activities and associations. Taylor provides an extensive account of x-ray research and development (1927-1962) as well as of his own work, and describes: the development of the Radiation Laboratory (late 1940s) and his years as associate director there (1962-1964); his work as executive director of emergency planning for the National Academy of Sciences (1965-1972), and as president of the National Council on Radiation Protection and Measurements; World War II work first with Merle Tuve on the proximity fuse, and from 1943 leading an Operations Research Section stationed in England. The travel chapters contain accounts of many radiology conferences and other related topics. Taylor's many committee and society posts are mentioned in his chapters on professional life; chapter 16 describes Taylor's extensive involvement as a consultant to the Department of Justice in a series of litigations against the U.S. Government (1982-1985). Additionally, a few of the 25 appendices are connected with his professional life.
