This is a reprint of an article written by Peter Drucker for Technology and Culture, Vol. I, No. I, Winter 1959. Drucker states that society uses limited definitions of technology and that it is more than simply mechanical artifacts. He goes on to say the study of development and history of technology should expand to include the concept of work, for both work and tools have a strong influence on each other. He then goes on to explain the history of work and its relationship to tools, processes, and products. This was originally a section of a larger publication and retains the same page numbers.
