G. J. Zuckertort
Zuckertort came to faith through the preaching of Wendt, a missionary with the London Jews Society. In 1836 he was appointed assistant missionary in Lublin. There he preached to his own relatives and had the joy of seeing one, a physician, come to faith. The doctor’s wife came to faith four years later, and their four children also confessed faith.
Zuckertort was the father of Johannes Zuckertort (1842-1888) a writer, physician, linguist and famous chess player who founded the UK based Chess-Monthly, one of the era’s most influential chess magazines. Johannes died of a stroke following two yeas of failed health, at the age of 45. A short biography of Johannes reveals that his father married the Baroness Krzyżanowska (Krzyzanovska). Because the Christian mission among the Jewish population in Russian-occupied Poland was frowned on by the authorities the Zukertort family emigrated to Prussia.
