Rowntree was founded in York in 1862 by Henry Isaac Rowntree, who was joined in 1869 by his brother the philanthropist Joseph Rowntree. It merged with rival Mackintosh in 1969 to become Rowntree Mackintosh. Rowntree was responsible for such British chocolate favourites as Kit Kat, Smarties, Aero, Fruit Pastilles and Black Magic, whilst John Mackintosh and Co. was behind Rolo, Munchies, Caramac and Quality Street.
The company went public in 1987 and was the subject of a takeover battle between Nestlé and Jacobs Suchard in 1988. Nestlé eventually won control with an offer valuing Rowntree at $4.55billion. After the Nestlé takeover the Rowntree chocolate ranges began to use the branding Nestlé-Rowntree, before eventually the Rowntree name was dropped from the packaging altogether, except on the famous 'fruit-pastilles' and 'fruit gums' where Rowntree retained its name on the packaging. The Mackintosh branding was dropped from all former Rowntree Mackintosh products, except for Toffos, which retained the Mackintosh branding.
The original factory was in the centre of the city of York, next to the River Ouse at Tanners Moat, but later relocated to Haxby Road in the north of the city.
Since Nestlé took over Rowntree Mackintosh's brands, there has been much criticism of the way that the company has changed the brands. Nestlé accepted that their purchase of the company was primarily for the five principal brands: Kit Kat, Aero, Polo, Fruit Pastilles, and Quality Street, rather than for capital assets. Since taking over Rowntree Mackintosh, the following changes have been made:
In September 2006 it was announced that the manufacture of "Smarties" was to be moved abroad causing job losses of 646 at the York factory
