Mary Lou Henner.
She is one of only 5 people in the world known to have a truly eidetic memory. She can remember every name anybody she ever spoke to in her entire life. She can remember every word of everything she has ever read to the letter. Recall not only what she was wearing 40 years ago on any date but what every single person she witnessed as well. She’s been tested under scientific scrutiny multiple times. It’s truly something to behold.
