Following his book on the origin of control engineering (1800-1930) the author now traces development through the critical period 1930-1955, widely identified as the period of 'classical' control theory. In the 1930s basic automatic control devices were developed and used in process industries, as were servos for the control of aircraft and ships and amplifiers for the telephone system and early computers etc.
