Haim Aharon Valero (1845–1923) was a banker, entrepreneur and a prominent figure in the Jewish community of 19th century Jerusalem. Under his direction, the Valero Bank, founded in 1848 by his father Jacob, acted as catalyst in the development of the Eretz Israel/Palestine. The bank’s capital and financial services were employed in the acquisition of land and building, helping transform Jerusalem and nearby townships from stagnation and poverty towards the modernization of the 20th century.
