Involved with the B'nai B'rith, an international service club for the Jewish communities, he was vice-president of the "Fraternitatea" lodge, and later as secretary-general of the supreme council of the Jewish lodges of Romania. In 1885 he published, in behalf of coreligionists in the small towns and villages, two pamphlets discussing cases of antisemitic persecution and Jewish reactions: "Radu Porumbaru şi isprăvile lui la Fabrica de Hârtie din Bacău" ("Radu Porumbaru and His Doings at the Bacău Paper Mill"), "Adevărul asupra revoltei de la Brusturoasa" ("The Truth on the Revolt in Brusturoasa").
