For a timeline on tools for information and knowledge work (starting with ink and paper) in my forthcoming book (Managing the Knowledge Workforce: Understanding the Information Revolution That's Changing the Business World), I am missing one bit of information: when the first office phone system was installed and who made it? 

If any IPers know this, please do e-mail me. 

Thanks in advance.
