From a New York Times obit by Richard Sandomir headlined “Louise Levy, Who Was Studied for Her Very Long Life, Is Dead at 112”

Louise Levy, who along with hundreds of others 95 and older was part of a study to understand how their genetic makeup led to their good physical and cognitive health during extremely long lives, died in Greenwich, Conn.

Her daughter, Lynn Neidorf, said Mrs. Levy had broken a hip two months ago but, after surgery and rehabilitation that had her moving with a walker, had developed an infection that weakened her.
