Four sons had accompanied Aaron de Sola in his flight from Lisbon in 1749, of whom the eldest, David, was the great-grandfather of the Dr. Abraham de Sola who forms the chief subject of this sketch. The youngest of Aaron de Sola’s, sons, Dr. Benjamin de Sola, attained to a foremost place among the practitioners of the eighteenth century. He was court physician to William V of the Netherlands and was the author of a large number of medical works. The other two sons of Aaron de Sola settled in Curacao, and one of them was the grandfather of General Juan de Sola, who became so distinguished as a commander of cavalry under Bolivar and Paez when the South American states revolted from Spain. He took part in the decisive battle of Carabobo, and led the charge on Puerto Cabello when that city was stormed by Paez, receiving a sabre wound during the fight. After the restoration of peace he held important public offices during the Paez regime. The Rev. Abraham de Sola, LL. D., was born in London, England, on the 18th of September, 1825. His father, David Aaron de Sola, was senior minister of the Portuguese Jews of London, to which city he had been called from Amsterdam, and was eminent as a Hebrew author, having produced among many other works an elegant translation of the Jewish Forms of Prayer; also, in conjunction with Dr. Raphael, an edition of Genesis, very valuable to biblical students on account of its commentaries and copious notes, and the first English translation of Eighteen Treatises of the Mishna. His mother was the daughter of Dr. Raphael Meldola, chief rabbi of the Spanish-Jewish congregations of Britain. The Meldolas had given eminent chief rabbis to Europe for twelve generations. Abraham de Sola received careful tuition in all the usual branches of a liberal education. He became early engrossed in the study of Oriental languages and literature and of theology, and continued to devote his attention to those subjects until he acquired that profound knowledge of them which subsequently won him so prominent a place among scholars. Having been offered the position of rabbi of the Spanish and Portuguese Jewish Congregation of Montreal he accepted the call and arrived in this city in the beginning of 1847, and here, for over thirty-five years, he continued to minister to the spiritual wants of his people. His able pulpit discourses soon attracted attention. Dr. de Sola’s abilities, however, were not destined to be confined exclusively to his official duties. Before leaving London he had been associated in the editorial work of a Hebrew journal, The Voice of Jacob, and soon after his arrival in Canada he delivered a course of lectures on Jewish history before the Mercantile Literary Association. In 1848 he published his “Notes on the Jews of Persia under Mohammed Shah,” and also “A History of the Jews of Persia.” Within the same year there appeared his important work on “Scripture Zoology.” Soon
