Joshua Lederberg studied bacteria and viruses from the viewpoint of transduction. Thus genes that convey virulence could be made more virulent or transferred to bacteria that did not normally act as disease vectors.
A subcommittee of the American Society of Microbiology was established at the beginning of World War II, but extended well beyond World War II. The purpose of this subcommittee was to review issues related to biological warfare. Of course, this is very legitimate. However, perhaps an unstated function was also the examination of research that might pertain to biological warfare: thus, censorship.
The following documents establish connections between Joshua Lederberg and Camp Detrick Biological Warfare research.
Regarding the report of the FAS committee on Biological Warfare
The focus of this letter is the use of agricultural pathogens
which would not incur retroaction (retaliation or the use of
biological weapons that could only be specifically targeted
against a particular geographic or climatic area). Insofar
as biological warfare might be targeted against humans,
Joshua Lederberg states that the possibility of retaliation,
as well as subsequent exclusion of military invasion, must
be taken into account. Note that at no point does Joshua
Lederberg raise any moral objections; in fact, he suggests
that the public should be 'educated' to allay its fears of,
and moral objections to, biological warfare.
