Third son of Abraham de Sola (No. 23); born at Montreal, Canada, Aug. 15, 1858. He has taken an active part in the Zionist movement since its inception, and was largely instrumental in establishing it in Canada. He held the presidency of the Federation of Zionist Societies of Canada from 1899 to 1905, was elected member of the Actions Committee at the Fourth Congress, London, 1900, and at subsequent congresses, and is a Canadian trustee of the Jewish Colonial Trust.
Since 1887 he has been managing director of the Comptoir Belgo-Canadien, the steel and construction trust of Belgium, and in that capacity he has constructed a number of Canada's public works, including many railway and highway bridges. His close association with the development of Belgium's industrial relations with Canada led to his appointment as Belgian consul at Montreal in 1905.
