He was a corresponding member of the St. Petersburg Academy of Science, and for valued work in sanitation was made a hereditary honorary citizen by the Russian government. Owing to his interest in Jewish matters, he was requested by the government to draw up a curriculum for the Jewish school at Uman in the government of Podol. In 1849 the title of collegiate councilor was conferred upon him; and in the same year he was elected a member of the Odessa English Club (composed of Russian noblemen).
