Kronenberg was born the son of banker and railroad tycoon
Leopold Stanisław Kronenberg (1812–1878) and his wife Ernestyną Rozalią Leo (1827–1893). Both parents came from Jewish families which had converted to Protestantism—the Kronenbergs, to
Calvinism. Leopold Julian Kronenberg's five siblings were banker
Stanisław Leopold, composer
Władysław Edward, Tekla Julia, Marię Różę, and Różę Marię Karolinę. After graduating from
gymnasium, he studied law, then took up the study of agriculture at
Bonn and Poppelsdorf. While his father was still active, Kronenberg managed the
Saint Petersburg branch of the
Warsaw Commercial Bank. In 1887, however, he was obliged to resign, on account of his brother's illness, in order to look after the management of the
railway lines in which the latter was interested and of the Commercial Bank of Warsaw. Kronenberg took an active interest in various useful public institutions. He was president of the Society for the Mutual Help of Musical Artists, a working member of the
Polytechnical Committee in Warsaw, etc. In recognition of his distinguished services in connection with great commercial undertakings, he was made a hereditary baron of the Russian empire in 1893. Valuable musical compositions by Kronenberg have been published under the pseudonym "Wiejesky". Married to famous soprano
Józefina Reszke (1855–1891), he had two children: Baron (1891–1971) and Baroness (1889–1969) the last of her family. Shortly before his death, Leopold Kronenberg converted to Catholicism so that he could be buried next to his wife in the family vault at Warsaw's
Powązki Cemetery. ==See also==
