Henry Singleton retired as Teledyne Chairman in 1991, and was replaced by George Roberts; William P. Rutledge was named President and CEO. Roberts then retired in 1993 and was replaced by Rutledge; Donald B. Rice, previously Secretary of the U.S. Air Force, was then named President and CEO. Many companies had been sold during the prior several years, and in 1993, through consolidations, the number was further reduced from 65 to 18. In January 1995, Teledyne Electronic Systems was sold to Litton Industries, essentially ending the business on which Teledyne had originally been formed.
