Carl Gustav Jung (1875-1961), Swiss doctor and psychologist. A close associate of Sigmund Freud for a number of years, then went his own ways. C.G. Jung first reported on his findings of using a GSR Meter in 1907 in an article in "Journal of Abnormal Psychology". A summary in German is quoted below. It is from a German Bio feed-back website at: WWW.Skinktalk.de
The first scientist known to have used a Meter in psychological research was Tarchinoff, who in 1888 discovered the phenomenon of skin resistance. He found that a person's resistance to the passage of a tiny electric current through hand held electrodes would vary according to the subject's emotional state. The simple psycho-galvanometer he invented to investigate this phenomenon was one of the earliest tools of psychological research.
