Dear Otto,

You may remember I recently questioned you
how you first heard about Avery.
Cleaning up my correspondence files, I
realize you had already answered my question.

This was doubtless in response to my request
for a reprint of your 'article'. I hope
to see you again in June at ACMR.

Dear Prof. Lederbsrg!

This is*only a riherate of the wonderful inveutigqtion of
grof. O.T,Avery and his coworkers about the 'l'ype transforma-
tions of pneumooocci. Uuring'the war my collegues could not
e;et a reprint of this important flublication. xhat's why 1
gave a referate, sending it $0 the "Angewandte Chemis" in
march 1945.

Since 1,945/46 other investigations about the same problem
have b&en,publi&ed by.'l?rof,Andr6 Boivin (now director of
ari institute of the Fr,*,Tch U,ylversity at Strasbqurgl. He WAS
                                " i*
