Professor Andrew Fyfe FRSE FRCSE PRSSA PRMS (18 January 1792 – 31 December 1861) was a Scottish surgeon and chemist.Following early studies on Fox Talbot's newly created photographic techniques he was one of the first (1839) to work out the theory behind positive rather than negative prints.He had an amateur interest in photography but appears not to have pursued his own theories (later very important in the creation of moving images) and limited his experiments to ferns lying on chemical papers.He lectured privately on chemistry and pharmacy at Edinburgh for many years, having been assistant to Professor Thomas Charles Hope.[4] He retained this professorship till his death on 31 December 1861 in Edinburgh, however he stopped lecturing in the summer of 1860 due to ill health.
