Mary Coppola (also known as Mary Wehe de Coppola, Tommy, Karen, and Keren Happuch) was one of the first personal secretaries of David Berg.
She was the protagonist of the Mo Letter, "To My 'Typewriter Queens'!" where Berg referred to her typewriter as her "womb where you conceive with my seeds of inspiration, and then bear me little babies! Every time you pull out a letter a new babe is born!".
