He preferred that his name be pronounced Louie. "It's like Louis Armstrong - he spelled his name Louis, but he liked it to be said as Louie," recalls Louie Bellson[1]. Armstrong was registered as "Lewie" for the 1920 U.S. Census. On various live records he's called "Louie" on stage, such as on the 1952 "Can Anyone Explain?" from the live album In Scandinavia vol.1. It should also be noted that "Lewie" is the French pronunciation of "Louis" and is commonly used in Louisiana. However, when referring to himself in "Hello Dolly!," he pronounces his name as "Lewis" ("Hello, Dolly. This is Lewis, Dolly"), pronouncing the 's'.
