Franz Leopold Lafontaine

Franz Anton Leopold Lafontaine (1756 to 1812), known in Poland as Franciszek Lafontaine, was a German-born military surgeon who made his career in Poland. He was born in Biberach, the son of a merchant, and became physician to Stanislaw August Poniatowski, the last king of Poland. He is known as the editor of the first Polish medical journal and for his work on catarrh, which a later Polish study of his writing examined. Through his daughter Sophie, who married Count Hans Moritz von Hauke, he was the maternal grandfather of Julia, Princess of Battenberg, and so an ancestor of several European royal families.
