Zénobe Gramme
Zénobe Théophile Gramme (April 4, 1826 - January 20, 1901) was a Belgian electrical engineer.
Born in Jehay , he was schooled as a carpenter in Ličge. In 1856 he established himself in Paris, where he worked for Ruhmkorff , a manufacturer of electro-magnetic devices.
In 1869, he invented the Gramme dynamo, a continuous-current dynamo capable of generating much higher voltages than the dynamos known thus far. Later he discovered that the device was reversible and could function as an electrical engine .
In order to manufacture his device, he founded in partnership with the French engineer Hippolyte Fontaine the Gramme Magneto-electric Machine Society in 1871. This factory specialized in dynamos and electrical generators.
Gramme died at Bois-Colombes, France.
