"you know him because he's known but because you're actually familiar with his work"
I cannot parse your statement, either there are some missing words, or some problem with your English.
Anyway, from my previous comment, you couldn't have any idea about how I got to know Feynman and his work. I haven't mentioned it at all.
FYI, I got acquainted with his work in 1996 when I enrolled into the university. I was studying maths, my dormitory roommate was studying theoretical physics, and he had several Feynman's books that were very interesting to me, though I must admit that sometimes the underlying apparatus was really complicated for an 18 y.o. greenhorn. But the principles were clear enough.
If my eyes rolled back any further in my head I could look into the past.
But you've proven your own point: you know him because he's known but because you're actually familiar with his work.
So again: textbook celebrity worship masquerading as intellectualism.
