Problem: East Prussia:

After the disastrous defeat of the Prussian Army at the Battle of Jena-Auerstedt in 1806, Napoleon occupied Berlin and had the officials of the Prussian General Directory swear an oath of allegiance to him, while King Frederick William III and his consort Louise fled via Konigsberg and the Curonian Spit to Memel. The French troops immediately took up pursuit but were delayed in the Battle of Eylau on 9 February 1807 by an East Prussian contingent under General Anton Wilhelm von L'Estocq. Napoleon had to stay at the Finckenstein Palace, but in May, after a siege of 75 days, his troops led by Marshal Francois Joseph Lefebvre were able to capture the city Danzig, which had been tenaciously defended by General Count Friedrich Adolf von Kalkreuth. On 14 June, Napoleon ended the War of the Fourth Coalition with his victory at the Battle of Friedland. Frederick William and Queen Louise met with Napoleon for peace negotiations, and on 9 July the Prussian king signed the Treaty of Tilsit.

Problem: Infection:

The medical treatment of infectious diseases falls into the medical field of Infectious Disease and in some cases the study of propagation pertains to the field of Epidemiology. Generally, infections are initially diagnosed by primary care physicians or internal medicine specialists. For example, an "uncomplicated" pneumonia will generally be treated by the internist or the pulmonologist (lung physician). The work of the infectious diseases specialist therefore entails working with both patients and general practitioners, as well as laboratory scientists, immunologists, bacteriologists and other specialists.

What is the non-medical mumbo jumbo term for pulmonologist?

A: lung physician

Problem: Frederic Chopin:

Although this period had been productive, the bad weather had such a detrimental effect on Chopin's health that Sand determined to leave the island. To avoid further customs duties, Sand sold the piano to a local French couple, the Canuts.[n 8] The group traveled first to Barcelona, then to Marseilles, where they stayed for a few months while Chopin convalesced. In May 1839 they headed for the summer to Sand's estate at Nohant, where they spent most summers until 1846. In autumn they returned to Paris, where Chopin's apartment at 5 rue Tronchet was close to Sand's rented accommodation at the rue Pigalle. He frequently visited Sand in the evenings, but both retained some independence. In 1842 he and Sand moved to the Square d'Orleans, living in adjacent buildings.

Where did they travel after leaving Barcelona?
