(su reading) transcription of Andre Lwoff's ltr. dated January 3, 1985 Dear Joshua: Alas I have not followed the illustrious route tread by so many writers, scientists, generals, politicians etc. I do not keep I have never kept a diary. Sometimes I regret it. Of course I remember the 1946 Cold Spring Harbor Symposium (it was my first visit to the states). In fact the only important scientific event the most Spectacular was the announcement of the sexuality of Escherichia coli. The transmission of characters from bacteria to bacteria was of course well known: the trans- forming principle. But that bacteria were able to copulate had to my mind never been foreseen. Somebody maybe I raised the ob- jection that symbiosis between two deficient bacteria could ex- plain your data but you masterally eliminated this hypothesis. Anyhow the fact behind sexuality was in itself interesting for those in love with bacteria but I wonder if anyone except you With kind regards. Andre Lwoff P.S. You may use this letter as you wish but please correct the mistakes concerning my English. whcok AL Sppeud Hood, Nety 1976)
