Salvador Dali is back home in his tower at the Dali Museum in Figueres, Spain, after a harrowing bout with pneumonia. Doctors said Dali, 84, who was admitted to the clinic Nov. 28 with serious heart and lung problems, was now strong enough to convalesce at home. His ambulance had a police escort to the museum from the Barcelona clinic where he had been treated and the artist was "glad to be back at home and in good spirits," according to Teresa Brugues, his private secretary.
