I have only professional details from a Google search. You probably
have most of these.
Christopher Tadgell teaches architectural history at the Kent Institute
of Art and Design and has lectured widely in Britain and the USA. Among
his publications are France: Baroque and Rococo Architecture and The
History of Architecture in India.
Christopher Tadgell is Senior Lecturer in Architectural History at the
Canterbury School of Architecture, Kent Institute of Art and Design. In
1985 he was Morgan Professor of Architectural Design at the University
of Louisville, Kentucky.
[He has published "The History of Architecture in India" Phaidon
Press, Limited. Singapore. 1990, which is apparently highly
recommended by specialists. I haven't seen it myself, but then I am not
an architectural historian or student of ancient Indian architecture]
He is also on the Board of Directors of the Academy of Ancient Music
That is what a quick search on Google turned up. Professional/academic
listings might turn up more, as might a "Who's Who" or the like
