Eartha Kitt is as well-known for her acting as well as her singing. She has a distinctive voice and, in song, she can be sweet and sultry. Her most popular song is the sexy "Santa Baby" which charted in the early 1950s, and her most well-remembered acting role is most likely that of the 'Catwoman' on the 1960s tv series "Batman", though she has been in many Broadway productions of note, too.
I sent her this vintage portratit photo in 1980, to her home in Beverly Hills, California, and she returned it within two weeks.
Ms. Kitt has her own website, with more information about her career and what she's doing today.
Here is a vintage film clip of her singing "Santa Baby".
