Who was this famous American?

Asimov was a genius.

I grew up reading his work, it took me to unimaginable places, and started my continuing love of sci-fi!

a master of Syfy

I was addicted to sci- fi in high school. Great escape

Can highly recommend the Foundation Trilogy, absolutely brilliant and, written in the early 50s, was way before its time, before sci-fi was really a widespread genre in literature or film.

baymax, I believe Elijah Bailey and Hari Sheldon are both Asimov characters . Hari Sheldon is the founder of The Foundation , the subject of the trilogy . I think John W Campbell is the editor publisher of an early SciFi magazine ( Amazing Stories(?)) where Asimov and many of the Science Fiction greats first appeared.

never heard of Hari Sheldon, so I guessed and got it right

Tacobelle, Ron Ferguson writes sci-fi books. He was a classmate of mine. I would like to read one of his books.
