Hattie Carnegie (March 15, 1886 – February 22, 1956) was a fashion entrepreneur based in New York City from the 1920s to the 1950s. She was born in Vienna, Austria-Hungary, as Henrietta Kanengeiser. By her early 20s, she had taken the surname Carnegie as an homage to Andrew Carnegie, the richest person in the United States at the time.[1][2]
