Memo from To: Alex Keynan JOSHUA LEDERBERG Dear Alex-~ While I was visiting at the H.U. Library, I noticed a collection of autographed volumes, including Les Prix Nobel. It would flatter me to be ablen to enter my own contribution along these lines; and I have therefore sent an incribed copy of LPN 1958 for this purpose. The inscription is from Inferno (26) which goes "Considerate la vostra semenza...." which I hope you will understand as helping to justify the acceptance of this gift. Sincerely, PROFESSOR JOSHUA LEDERBERG Department of Genetics School of Medicine Stanford University Stanford, California 94305
