The Weaver Collection of Thornhill
In 2003, the Weaver Collection of Thornhill was donated to the Archives through the Estate of the Alf and Laura Weaver. The Weavers created a remarkable photograph collection accompanied by research notes. The collection, which is arranged by street or subject, includes many historical photographs collected by the Weavers. Alf Weaver documented local buildings, people, and events from the 1940's to the 1990's. The collection is particularly valuable in its documentation of Thornhill's transition from a rural to sub-urban community.
