The Directory of Lost Companies
ControlGlobal.com introduces The Directory of Lost Companies, our first wiki. Using the list found in the Instrument Engineers Handbook (with permission), we have identifi ed more than 200 companies whose
name, ownership or product line has changed significantly over the period from 1990 to 2005.
During this time, the instrumentation, systems and automation industries have undergone significant
change not just of a technical nature, but in terms of consolidation among instrument and control system
suppliers. The result: Many automation professionals are left wondering what happened to those original companies. Where are they now? Who owns them? What happened to their product lines? Can replacement parts or old manuals still be found? Our wiki can help you learn where these companies stand today.
What exactly is a wiki, you ask. Think of it as a participatory encyclopedia.
Weve seeded our list of lost companies with what we know about them. You can add what you know about them or about those weve missedincluding any that have disappeared since 2005and in the end, we will all know more about these lost companies and their products.
