The contemporary caption on this print read: 'One of the fleet of tankers which hold 2,500 gallons of milk each, at the Horlicks malted milk factory at Slough in Berkshire.' Horlicks Malt Milk was the first succesful dried milk food in the world. The company was founded by two brothers who emigrated to the United States in order to manufacture in 1873 a malted infant food based on Liebigs Extract. Both the partnership and the product were extremely succesful. In 1883 they produced the first 'malted milk' - based on a mash of malted barley and wheat flour mixed with fresh whole milk and dried. The resultant product, in powder form, could be mixed with hot water to give a complete, sterile beverage suitable for infants and invalids. In 1890, James Horlicks opened an office back in London and in 1906 built the factory in Slough to exacting specifications. The company continued to be extremely succesful worldwide and in 1969 became part of the Beecham Group.
