Gramme, Zénobe-Théophile

▪ Belgian scientist
born April 4, 1826, Jehay-Bodegnée, Belg.
died Jan. 20, 1901, Bois-Colombes, France

      Belgian-born electrical engineer who invented (1869) the Gramme dynamo, a continuous-current electrical generator that gave a major impetus to the development of electric power.

      An indifferent student, Gramme preferred to work with his hands. In 1856 he began work in a Paris factory that fabricated apparatus for the infant electrical industry. In 1869 he conceived his continuous-current dynamo and in 1871 showed to the Academy of Sciences a working model that produced much higher voltages than did previous dynamos (electric generator). Later that year, in partnership with Hippolyte Fontaine, also an inventor, he began manufacturing his dynamo. In 1873 a Gramme dynamo was exhibited at the Vienna exhibition, where it was demonstrated that the device was reversible and could be used as an electric motor.
