In Strange Brains and Genius (page 297), Clifford A. Pickover writes that these people "have been considered" to have had temporal lobe epilepsy: Peter the Great, Alexander the Great, Moliere, Eugene Delacroix, Rasputin, August Strindberg, and actor Richard Burton." He does not say considered by whom.

Eve LaPlante agrees about Moliere and Eugene Delacroix in Seized: Temporal Lobe Epilepsy as a Medical, Historical, and Artistic Phenomenon (HarperCollins, May 2000, ISBN 0595094317) and adds van Gogh.
