The simplest answer is to use the subject's full name, followed by "biography" or "biography of" if you need to be more specific. For example, the title of a biography about Abraham Lincoln might be "Abraham Lincoln: A Biography" or "Biography of Abraham Lincoln."
If you want to get more creative, you can use a quote from the subject, a significant event from their life, or even a famous quote about them. For example, a biography about Marie Curie might be titled "A Life of Firsts: The Marie Curie Story" or "The Pioneering Spirit of Marie Curie."
Ultimately, the best way to title a biography is to be creative and reflective of the subject's life and achievements.
