Henry Cavendish and Asperger’s syndrome: A new understanding of the scientist

Although it has recently been suggested that Henry Cavendish (1731–1810) suffered from Asperger’s syndrome (James, 2005; Sacks, 2001), there has yet to be a systematic exploration of this claim. For various reasons, Cavendish is considered here through the diagnostic framework described by Gillberg (1989), with further support from the DSM-IV (APA, 1994). The potential for such a retro-diagnosis is evident, given Cavendish’s biographers’ lament of Cavendish as the ‘incomplete man’: the oddly misanthropic man characterised by negations. Such an impression is evident in the memoirs of Cavendish’s contemporaries but finds its best expression in Wilson’s (1851) biography. With a new and cautious interpretation from an Asperger’s syndrome perspective, this fragmented picture dissipates and Cavendish emerges as a man of remarkable intellect whose syndrome stunted his social development and expression, yet so crucially enabled his research into a paradoxically catholic taste of scientific study. Topics relevant to a ‘retro-diagnosis’ are first addressed, before Cavendish is compared to Gillberg’s and the DSM-IV criteria.
