This is the final photo relating to Charles Thompson in this wee series. It is I think the science / chemistry room in Mountjoy School where he taught and which presumably was a handy place to develop films and make prints. No date on it, 1930s at a guess.
Apart from photography, Charles had an interest in local placenames in Wicklow and took notes in the various valleys. Many of these he passed onto Liam Price, where he appears as CGT in Price’s notes. The adjoining photo is a sample of some of the information he collected in the 1920s and 30s.
As mentioned previously, if anyone else is aware of old photos or placename records in other private collections, please do let us know.
