Sir Henry "Harry" Lauder (/ˈlɔːdər/; 4 August 1870 – 26 February 1950) was a Scottish music hall and vaudeville theatre singer and comedian, and a substantial landowner.
He was perhaps best known for his long-standing hit "I Love a Lassie" and for his international success. He was described by Sir Winston Churchill as "Scotland's greatest ever ambassador!" He became a familiar world-wide figure promoting images like the kilt and the cromach (walking stick) to huge acclaim, especially in America. Other songs followed, including "Roamin' in the Gloamin", "A Wee Deoch-an-Doris", and "The End of the Road".
By 1911, Lauder had become the highest-paid performer in the world, and was the first Scottish artist to sell a million records. He raised vast amounts of money for the war effort during World War I, for which he was subsequently knighted in 1919. He went into semi-retirement in the mid-1930s, but briefly emerged to entertain troops in World War II. By the late-1940s he was suffering from long periods of ill-health and died in Scotland in 1950.
