Thallium was discovered both by William Crookes and by Claude Auguste Lamy, working independently. See: (1) William Crookes (March 30, 1861) "On the existence of a new element, probably of the sulphur group," Chemical News, vol. 3, pages 193-194; reprinted in: Philosophical Magazine, vol. 21, pages 301-305 (April 1861); (2) William Crookes (May 18, 1861) "Further remarks on the supposed new metalloid," Chemical News, vol. 3, page 303; (3) William Crookes (June 19, 1862) "Preliminary researches on thallium," Proceedings of the Royal Society of London, vol. 12, pages 150-159.
