Of course we all knew of Avery's paper soon after its publication. I recall knowing about in 1945, possibly earlier. I
asked Bob B[?] when he first knew of it. He said Jack Schultz saw it as soon as the journal JEM arrived in the Lankenau library
and went around the lab telling everyone about it in great excitement.
I liked your "Biological Innovation" chapter. I don't publish on this, but talk about it a lot in lectures here
and elsewhere and on the whole my views agree closely with yours.
