Biographical history

John R. Henderson was born c.1928, the great nephew of John Mackintosh of Halifax, founder of Mackintosh’s confectionary company. He completed a degree in civil engineering at Trinity College, Dublin, and worked for the Irish Electricity Board and then Wimpey and McAlpine construction, before joining Mackintosh’s as a management trainee in 1957.

His training took place at the company’s Albion Mills and Queen’s Road sites in Halifax. He went on to work as Quality Control Manager at Albion Mills in the 1960s and 1970s, where he played a central role in the development of the new Toffee Crisp chocolate bar, based on the crispy cake his wife Edith used to make for their children, Charles and Jill. He also worked on the development of Mint Cracknells, Tooty Frooties and Caramacs.

In 1982 he became Managing Director of another Halifax based firm, Yorkshire Moulds, supplying plastic moulds to confectionary companies. He remained with Yorkshire Moulds until his retirement in 1995. A prominent local businessman, Henderson was involved in a variety of community organisations, including Halifax Housing Association, Mackintosh Homes, the Waterhouse Trust and Halifax Rotary Club.

John Henderson died in December 2011.
