Crazy Lou (died 1886) was the pseudonym of a New York showgirl and prostitute who was a well-known personality in the Bowery during the late 19th century.
She instead fell into the hands of procuresses who sold her to one of the Seven Sisters brothels, a group of seven well-known establishments located in a residential area of brownstones on West 25th Street.
She regularly performed at some of the top bars and social clubs in the city including establishments owned by Tom Gould, Harry Hill and Billy McGlory.
She spent her last years at Frank Stephenson's Black and Tan Club where, even after retirement, she remained a regular, typically staying from midnight until 2:00 am.
Yet she continued going to the Black and Tan, where she had a regular table and was personally served a tumbler of whiskey by Stephenson free of charge.
