Charles Piazzi Smyth
In his lecture to Edinburgh Photographic Society
0n 10 December 1869, Charles Piazzi Smyth, Astronomer Royal for Scotland, gave
encouragement to the poor man travelling abroad with a camera. He spoke
of how resourceful and inventive such photographers could be.
He went on to describe his own work
four years previously, using very small
negatives and producing stereo views of the Pyramids in Egypt
