This fonds consists of research notes, manuscript drafts, photocopies of primary sources, correspondence, and a few original documents and photographs acquired by David Roberts in the course of his research for a book about Gordon M. McGregor and the Ford Motor Company of Canada in Windsor, Ontario. The fonds is organized into two series, reflecting the two accessions through which the material was received and arranged. Series I primarily contains draft manuscripts, research correspondence, and research notes relating to McGregor’s personal and professional life, the automobile industry, and McGregor’s contemporaries. Series II principally contains research correspondence, images, and research notes from Windsor newspapers and the Ford of Canada Archives.
