* Lives of specific people?
* This is a huge category! Think of biographers, historians, novelists, filmmakers, playwrights, and even musicians who tell stories about real people.
* Lives of the artist themselves?
* Autobiographical artists exist in all mediums, from painters and sculptors to writers and musicians.
* Lives of people in general?
* Social realists, documentarians, photojournalists, and even some abstract artists might be considered to base their work on the lives of people, even if they don't focus on specific individuals.
To give you a more specific answer, could you clarify what kind of "lives" you're interested in?
For example, are you looking for:
* Artists who portray the struggles of everyday people?
* Artists who document historical events?
* Artists who explore the human condition through their personal experiences?
* Artists who create fictional stories inspired by real lives?
Once you tell me more about what you're looking for, I can give you a more precise list of artists.
