After sojourns in Lwów and several smaller localities, on 20 February 1869 they moved to Kraków (until 1596 the capital of Poland), likewise in Austrian Poland. A few months later, on 23 May 1869, Apollo Korzeniowski died, leaving Conrad orphaned at the age of eleven. Like Conrad's mother, Apollo had been gravely ill with tuberculosis. The young Conrad was placed in the care of Ewa's brother, Tadeusz Bobrowski. Conrad's poor health and his unsatisfactory schoolwork caused his uncle constant problems and no end of financial outlay. Conrad was not a good student; despite tutoring, he excelled only in geography. At that time he likely received private tutoring only as there is no evidence he attended any school regularly. Since the boy's illness was clearly of nervous origin, the physicians supposed that fresh air and physical work would harden him; his uncle hoped that well-defined duties and the rigors of work would teach him discipline. Since he showed little inclination to study, it was essential that he learn a trade; his uncle saw him as a sailor-cum-businessman who would combine maritime skills with commercial activities. In fact, in the autumn of 1871, thirteen-year-old Conrad announced his intention to become a sailor. He later recalled that as a child he had read (apparently in French translation) Leopold McClintock's book about his 1857–59 expeditions in the "Fox", in search of Sir John Franklin's lost ships ' and '. He also recalled having read books by the American James Fenimore Cooper and the English Captain Frederick Marryat. A playmate of his adolescence recalled that Conrad spun fantastic yarns, always set at sea, presented so realistically that listeners thought the action was happening before their eyes. In August 1873 Bobrowski sent fifteen-year-old Conrad to Lwów to a cousin who ran a small boarding house for boys orphaned by the 1863 Uprising; group conversation there was in French. The owner's daughter recalled: Conrad had been at the establishment for just over a year when in September 1874, for uncertain reasons, his uncle removed him from school in Lwów and took him back to Kraków. On 13 October 1874 Bobrowski sent the sixteen-year-old to Marseilles, France, for Conrad's planned merchant-marine career on French merchant ships. His uncle provided him with a monthly stipend as well (set at 150 francs).
