William Hall Findlay was a Scottish photographer and historian. Between the 1950s and the 1980s, he took photographs of the townscape of Perth, Perth and Kinross, illustrating its transition into the modern era. Many of these were featured in his 1984 book Heritage of Perth. Around a quarter of his lifetime collection of 25,000 photographs are now housed in Perth's A. K. Bell Library.

The A. K. Bell Library is an historic building on York Place in Perth, Perth and Kinross, Scotland. The building was originally a hospital before becoming a municipal building and later a library. The central section of the building is Category A listed. The lodge to the estate, now removed from its original location, is Category B listed.
