We all remember Carl Sagan.

Lysithea knew him well, apparently? Do you believe it? She writes:
He worked with Carl Sagan and the Shoemakers - he was friends with the Shoemakers, Carl was another story though.

"It was fascinating listening to him go off on his work, and when he found out that I could converse with him about it, he pulled out his maps and we started talking. I went to house frequently - much to my best friend's dismay (she was his granddaughter) because she usually got dragged into our conversations and as she described it: it just wasn't her "cup of tea" - and I found the world of intellectuals he described to be quite appealing."
