In this day, when insecure living and working conditions have come to be recognized as a great problem in social security, it is interesting to see how one industrial firm attacked that problem almost a century ago. The firm was the Waltham Watch Co., and the executive responsible for its labor management was Aaron Dennison. The watch company was one of three large manufacturing enterprises started by Dennison. The others were the Dennison Manufacturing Co., of Framingham, Massachusetts, and the Dennison Watch Case Co., of Birmingham, England.
