Records relating to Jacob's Biscuit Factory in Bishop Street (1880-1975) and Tallaght (1975-2009) deposited by Valeo Foods and Douglas Appleyard. The archives of W & R Jacob and Company were acquired by Dublin City Library and Archive in 2012. Comprising both the business archives donated by Valeo Foods and the Appleyard Collection donated by Douglas Appleyard, the 330 boxes contain a wide range of records, relating to over 150 years of biscuit making in Dublin. This archive represents a rich and significant contribution to the study of business and commercial life in Dublin in the late 19th and 20th centuries. It also offers valuable information about life in the community of over three thousand Dublin workers, mostly women, who were engaged at any given time during most of the company’s manufacturing period. Following a major cataloguing project, the collection was opened for public access in the Reading Room of Dublin City Library and Archive in 2016.
