Wording is so important in these discussions:

Lloyd in fact did not say it happened, only that he "thought" it should
happen.  The "falsehood" was never posted.

 >FWIW, my Britannica clearly shows the listing to which Lloyd refers under

Lloyd did not "refer" to any "listing" in his original post that I am aware of.

  >I quote: "1948 PAUL HERMANN

Yes, Dr. Muller  got the Prize, but not for discovery of DDT, only for
recognition that it was effective in military and public health
matters.  The material was actually discovered (synthesized) in 1874.

DDT, known as Chlorophenothane, was first synthesized in 1874. One of its
first uses was in the military; soldiers often were advised to shampoo with
DDT to control infestation. In 1948 Paul Muller, a Swiss chemist, was
awarded the Nobel Prize for Medicine and Physiology for his recognition of
DDT as an effective insecticide with the ability to be used to improve
public health as well as military hygiene.
