Henry Norris Russel impressed the physicists and astronomers of his day the way physicists and astronomers sometimes impress the more credulous members of the public: He was a "brain," not just smart, but supersmart, so quick that he often left his listeners far behind and afraid to ask questions for fear of appearing stupid. He seemed to have every conceivable fact, even tables of logarithms, committed to memory.
