Sir William Crookes was poisoned by thallium!
I saw the article in Paranormal Review and the mention of thallium poisoning, but I have never heard about it before. It fits of course - it is necessary to demonstrate that Crookes was out of his mind because experimental evidence that does not agree with the standard settled world view has to be discredited in some way (if the evidence is produced by obscure scientists it can be ignored, of course, and the scientists' careers made to suffer, but if it is produced by a great scientist and so cannot be ignored it must be discredited). The same thing goes on everywhere in science and in every context: Alfred Wegener put forward the idea of continental drift in 1912 but was discredited on the grounds that he was a meteorologist not a geologist and so was unqualified to pronounce on geological questions, and the idea was not accepted until 1965.
In another context, though, the article by Bernard Carr is a very positive description of how appropriate it is that a physicist should get involved in the paranormal,
