What I do know comes from second and third hand sources. People who worked with people who worked with Doctor Bowman.
I'd love to say he is a great human being, but he's been described as rude, arrogant, prone to act without considering the risks, and having a foul temper.
On the plus side, he made sure our brains would have the self control he knew he lacked.
That does not make me happy. But for maximum flexibility… A jerk with a conscience is not a bad starting point.
