In 1870, Gram, regardless of the Florentine professor Antonio Pacinotti , who proposed the same principle back in 1860, invented the winding system of dynamo-electric machine anchors named after him, which made it possible for the first time to industrially produce electric current.
On July 17, 1871, the French physicist Jules Jamen presented the Gram machine of the Paris Academy of Sciences , in 1873 Gram was awarded a gold medal at an exhibition in Vienna , in 1875 - a medal of the society promoting the development of electrical engineering; in 1876-1876, the Societé des machines Gramme was founded to operate the invention of the Gram; in 1878, for the first time, Gram machines were used to illuminate Paris .
