In 1849, 22-year-old Londoner Alfred Lamb, son of wine and spirits merchant William Lamb, blended 18 different rums from Barbados, Guyana, Jamaica and Trinidad to produce Lamb’s Navy Rum. His company was to take the name of Alfred Lamb & Son. The use of the word "navy" dates back to the British Navy issuing a daily ration of rum to its sailors. It had previously given its sailors French brandy, but the 1655 conquest of Jamaica gave it access to rum, which it quickly exploited. The 1970 decision of the British Royal Navy to end issuing a daily rum rations to its sailors inspired the brand that year to adopt the advertising campaign, "Join the Lamb’s Navy."
