Thomas Annan, a prominent mid-19th century photographer of Glasgow, captured the city's transformation during its industrial expansion. Best known for his haunting photographs of Glasgow's narrow alleys between 1868 and 1871, Annan's work is considered a precursor to documentary photography. This book examines his diverse photographic projects arranged by his publication history, featuring seven works that include private albums and commercial books. Subjects such as the city's streets, the Loch Katrine aqueduct, Glasgow College, the cathedral, and country estates are explored. The book includes full-color reproductions and an introductory essay on Annan's influential career.
