The Nobbs fonds consists of the work of Percy Erskine Nobbs, George Taylor Hyde, Nobbs and Hyde, Nobbs and Valentine, and Nobbs and Nobbs. 526 projects are documented in the Percy Erskine Nobbs Fonds. Architectural drawings form the core of the fonds, providing a comprehensive listing of the drawings by Percy Nobbs and his associates. Arranged chronologically, the inventory reflects respectively the development of the partnerships Nobbs and Hyde (1910-1944), Nobbs and Valentine (1945-1950), and Nobbs and Nobbs (1950-1960). Hugh A.

The fonds consists of the records of the Zoological Society of Montreal for the entirety of its existence, from 1964-2016. These records were generated in the pursuit of the Zoological Society’s goal to enhance public awareness of wildlife conservation issues through speakers, film screenings, field trips, special events, and large projects.
