This next man has had both an influence on the right and the left in this country.
He was notorious for his work at understanding group psychology. At one point, he was accepted as a member of a high-ranking mobster's gang in Chicago. He spent the time studying every aspect of how the group functioned. He considered the mob "a utility" - whatever someone wanted, it provided, much like the electric company providing heat and light when you want it in your house.
That's it - he must have something to do with masks. Be back in a bit ...
Yes, this is Paul Berger, the French physician and surgeon, who invented the surgical mask.
A note on surgical masks:
It is designed to prevent infections in patients and treating personnel by catching bacteria shed in liquid droplets and aerosols from the wearer's mouth and nose. They are not designed to protect the wearer from breathing in airborne bacteria or viruses whose particles are smaller.
This caricature in wiki cracks me up, so I'm including it here. Note that Berger is in the middle; two of his colleagues from the Faculté de médecine de Paris are with him - Victor Cornil on the left, holding a pair of lungs, and Felix Guyon on the right with a syringe. Don't know the story, but I suppose I could look up those guys & discover their claims to fame.
Modern NICUs likely owe this man a debt of gratitude, although his credentials could not be proved. Nonetheless, this man was well respected by a number of obstetricians and pediatricians, and of course by the parents whose newborns he nursed to good health.
Psalm 121:1-2 I will lift up mine eyes unto the hills, from whence cometh my help. My help cometh from the Lord, which made heaven and earth.
