||Title: Principios deberes y practicas del Judaismo destinado á la instrucción oral y reliosa de la juventad Hebrea
A work on the basics of Judaism written in Spanish for the instruction of Jewish youth. It was published by the Jewish Colonization Association (ICA) which was a philanthropic association to assist Jews in depressed economic circumstances or countries of persecution to emigrate and settle elsewhere in productive employment, founded by Baron Maurice de Hirsch in 1891. It was incorporated in London as a joint-stock company whose other shareholders were Baron Edmond de Rothschild, J. Goldsmid, Sir Ernest Joseph Cassel, F. D. Mocatta, Benjamin S. Cohen, S. H. Goldschmidt, and Salomon Reinach. In 1893 de Hirsch's shares were distributed between the Anglo-Jewish Association, and the Jewish communities of Brussels, Berlin, and Frankfort. The basic endowment was later increased to £8,000,000. The association's offices were located in Paris until transferred to London in 1949. De Hirsch was president until his death in 1896. He was succeeded by Salomon Goldsmid (1896), Narcisse Leven (1896–1919), Franz Philippson (1919–29), Lionel Leonard Cohen (1929–34), Sir Osmond d'Avigdor Goldsmid (1934–40), Leonard Montefiore (1940–47), and Sir Henry Joseph d'Avigdor Goldsmid. De Hirsch's immediate plan envisaged a mass emigration of the Jews from countries in Europe, where they were persecuted, to Argentina, though circumstances forced ICA to give priority to the various needs of Jews in Europe.
Emigration was the cornerstone of ICA's activity throughout its history. From 1904 to 1914 ICA established 507 emigration committees in Russia, and a central office in St. Petersburg, with the approval of the Russian government. In New York the Hirsch Fund established a trade school in 1891 in order to prepare new immigrants for the task of earning a living. The large-scale immigration into America in the early 20th century led ICA and the Jewish Agricultural and Industrial Aid Society jointly to establish the Removal Committee. This organization linked immigrants in America with their relatives remaining in Europe. Information bureaus sprang up all over Europe, and by 1912 the Removal Committee had helped over 70,000 immigrants. In 1922 this organization was dissolved. After World War I many countries closed their doors to immigration, and new conditions demanded new machinery. ICA's initiative led to the creation of immigration societies in Canada, Argentina, and Brazil. In 1921 ICA called a conference in Brussels and in 1922 in Paris for the establishment of a united emigration association. The conferences failed, but in 1925 the United Evacuation Committee was formed by ICA jointly with Emigdirekt and the American Jewish Joint Distribution Committee (J. D. C.). In 1927 Hias (Hebrew Sheltering and Immigrant Aid Society), ICA, and Emigdirekt founded a new association, Hicem, which had established 57 committees in 21 countries by 1937. In 1928 ICA formed an emigration bureau in Moscow to supervise emigration from Russia, and at the instigation of ICA all the private organizations dealing with emigrants jointly set up a committee for their protection, with its seat in Geneva. From 1933 to 1939 ICA spent £800,000 on the emigration of Jews from Germany.
