Jules Denis, Baron du Potet or Dupotet de Sennevoy (12 April 1796 – 1 July 1881) was a French esotericist.
[3] His reputation was such, apparently, that a man was convicted of murder and executed based on evidence given by "one of Du Potet's clairvoyantes".
[4] He operated a free school of magnetism in Paris from 1826 on,[5] and from 1837 to 1845 practised magnetic healing in London,[6] where he successfully treated epileptic girls at the North London Hospital[3] and according to a letter to the editor of The Lancet his experiments became the talk of the town.
[8] An 1890 article in the English occult magazine Lucifer praises him as an ardent supporter of mesmerism whose "powerful voice" might have stopped the "travesty" of hypnotism.
[5] He was a member of the Theosophical Society; his writings were quoted extensively by Helena Blavatsky, who regarded him as an adept.
