Isidor Bush or Busch (January 15, 1822, Prague – August 5, 1898, St. Louis, Missouri) was a man of letters, publisher, and viticulturalist.
There Bush opened a store for the sale of newspapers and stationery, and, on March 30, 1849, published the initial number of Israel's Herald, the first Jewish weekly in the United States, which, however, lived only three months.
Bush assisted in forming Congregation B'ne El in St. Louis along with Daniel Block[3] and in establishing the Independent Order B'nai B'rith in the West, and was henceforth prominently identified with the Order, rendering especially useful service in connection with its endowment or insurance feature, and in forming the Cleveland Jewish Orphan Asylum.
He was elected a member of the Missouri state board of immigration to repair losses in population resulting from the war, which post he retained for twelve years.
He purchased a tract of land (named by him "Bushberg") outside the city, which became noted for its products; and he even sent large quantities of cuttings from his vineyards to France to replace ravages by phylloxera.
