Father Pitt has created a spreadsheet of information about buildings in Pittsburgh and their architects, and he offers it without warranty of any kind to the world at large. If you click on this link, you will be taken to the spreadsheet in Zoho Office:
Father Pitt’s Great Big List of Buildings and Architects
On line the file can’t be edited by anyone but Father Pitt, but you can download it in Open Office, Excel, and other common formats, and sort it and format it any way you like.
The file incorporates both original research and some data from a City of Pittsburgh historic-buildings survey, which Father Pitt adopts with gratidude. For that reason some information is duplicated. The City of Pittsburgh should not be held responsible for any inaccuracies in the Great Big List; those are old Pa Pitt’s fault. The entries that have no source listed are mostly the ones adopted from that original city survey.
A warning: Do not take these listings as accurate for any given building. Consider them starting points for further research. Father Pitt has attempted to document the source of the information in most cases, but those sources are themselves not always accurate. Especially when the source is a trade-magazine listing saying that a certain architect is drawing plans, remember that, in the words of an old English proverb, there’s many a slip ’twixt the cup and the lip, and more than once we find that an architect’s plans were rejected and a new architect hired.
