Edmond Julien
Edmond Julien († 1894 ) was a Belgian inventor.
For the positive electrode of his accumulators he created the Julien metal in 1884 , a hard lead alloy with approx. 4% antimony (and possibly 4% mercury), which is neither attacked by acid nor by electric current. The company L'Electrique in Brussels manufactured the batteries. The German licensee, the engineer JL Huber (Hamburg, Brauerstr. 34; * around 1844; † January 11, 1916) later improved it and made unsuccessful attempts in 1886 with a battery-powered tram.
The Julien electric street car was in 1885 at the World's Fair (Exposition Universelle d'Anvers) in Antwerp get the first prize.
With "Julien's Patent Electric Traction" a battery-powered tram was tested in Adelaide on Henley Beach in 1889 .
From July 2, 1887, a "Ferro-Carril" was also operated in the Jardim Botânico in Rio de Janeiro .
