Joseph Mortimer Granville (4 May 1833,Devonport – 23 November 1900,London) was an English physician, author and inventor known for having first patented the electromechanicalvibrator for relief of muscle aches, exclusively for male patients. It was also claimed byRachel Maines that the device was used to treat hysteria, by bringing women to orgasm, but her work is not historically accurate.
Granville qualifiedM.R.C.S.Eng. in 1856 andL.R.C.P.Lond. in 1861. He attained the higher medical degree M.D. in 1876 from theUniversity of St Andrews.[1]
In his earlier years he was much engaged in journalism, and was, we believe, a frequent contributor to the editorial columns oftheLancet. He practised at one time in Bristol, but afterwards settled in London, and gave particular attention to the treatment ofgout, upon which he wrote largely.[1]
In addition to his famous invention of an electric vibrator, he also invented asphygmograph and adifferential thermometer.[1]
On 1 December 1858 he married Mary Ellen Ormerud in Bristol.
In the late 1880s Granville invented the electric vibrator, a handheld electric operated device designed to relieve male muscle aches and pains.[2][3] Originally called a percusser or more colloquially "Granville's hammer", the machine was manufactured and sold to physicians. Rachel Mains claimed that many used the equipment to create "hysterical paroxysm" in their patients withfemale hysteria.[4] However, the publication of this theory has been described as representing "a failure in academic quality control"[4] by academic researchers who, on reviewing the primary sources from Maines' book, "found no evidence in these sources that physicians ever used electromechanical vibrators to induce orgasms in female patients as a medical treatment".[5]
Granville "argued specifically that it shouldn't be used on hysterical women".[6] In his 1883 book,Nerve-Vibration and Excitation as Agents in the Treatment of Functional Disorder and Organic Disease, he wrote, "I have never yet percussed a female patient ... I have avoided, and shall continue to avoid the treatment of women by percussion, simply because I do not wish to be hoodwinked, and help to mislead others, by the vagaries of the hysterical state."[7]
Granville was portrayed by actorHugh Dancy in the 2011 filmHysteria.
