The following telephone extension lists and other employee listings are included on this site in order to try to provide inforamtion as to who worked at Sadtler and when.

This early telephone extension listing from 1966 (?) provides only the names of company officers, department heads, supervisors and other personnel who might have been expected to receive outside phone calls on company business, such as analytical chemists and department secretaries.
Lower echelon employees are for the most part not listed, for example spectra lab technicians such as Wayne Liss, Frederick Mercaldo and Bill Simons among others are not named but were indeed employed with the company at the time.
