[Chris Scott]

I found this notice:

Reserved Seats 25 cents extra
TONIGHT
By special request
The Poor of London - How They Live
With Views of Whitechapel

Does anyone know who this Prof. Cromwell was please?

[Robert]

Chris, he seems to have given magic lantern shows and to have invented something called a stereoscope which looks like it might have been a kind of 3-D device.

Hi Robert
many thanks for that - very helpful
Would love to see his "Views of Whitechapel" slides!

Hi Chris

There's a book "The American Screen to 1907" by Charles Musser on Google books - I think it's a volume in the History of the American Cinema.

Yes, I wonder whether all Cromwell's stuff is in some museum somewhere in America.
