The Monte Carlo method came into concrete form
with its attendant rudiments of a theory after I proposed the possibilities of
such probabilistic schemes to Johnny in 1946 during one of our conversations.
It was an especially long discussion in a government car while we were driving
from Los Alamos to Lamy.
