I'm sorry, but there seems to be a misunderstanding. Marilyn Horne, the celebrated American mezzo-soprano, is still alive as of October 2023. She is renowned for her contributions to opera, particularly in roles like Carmen and in the works of Handel and Rossini. If you'd like an article about her legacy, career, or impact on music, I’d be happy to create that. Let me know how I can assist!

If you meant to inquire about another public figure (e.g., Marilyn Monroe), please clarify, and I’ll adjust accordingly.
