input: After Cantor's 1884 hospitalization, there is no record that he was in any sanatorium again until 1899. Soon after that second hospitalization, Cantor's youngest son Rudolph died suddenly on December 16 (Cantor was delivering a lecture on his views on Baconian theory and William Shakespeare), and this tragedy drained Cantor of much of his passion for mathematics. Cantor was again hospitalized in 1903. One year later, he was outraged and agitated by a paper presented by Julius Konig at the Third International Congress of Mathematicians. The paper attempted to prove that the basic tenets of transfinite set theory were false. Since the paper had been read in front of his daughters and colleagues, Cantor perceived himself as having been publicly humiliated. Although Ernst Zermelo demonstrated less than a day later that Konig's proof had failed, Cantor remained shaken, and momentarily questioning God. Cantor suffered from chronic depression for the rest of his life, for which he was excused from teaching on several occasions and repeatedly confined in various sanatoria. The events of 1904 preceded a series of hospitalizations at intervals of two or three years. He did not abandon mathematics completely, however, lecturing on the paradoxes of set theory (Burali-Forti paradox, Cantor's paradox, and Russell's paradox) to a meeting of the Deutsche Mathematiker-Vereinigung in 1903, and attending the International Congress of Mathematicians at Heidelberg in 1904.  In 1911, Cantor was one of the distinguished foreign scholars invited to attend the 500th anniversary of the founding of the University of St. Andrews in Scotland. Cantor attended, hoping to meet Bertrand Russell, whose newly published Principia Mathematica repeatedly cited Cantor's work, but this did not come about. The following year, St. Andrews awarded Cantor an honorary doctorate, but illness precluded his receiving the degree in person.  Cantor retired in 1913, living in poverty and suffering from malnourishment during World War I. The public celebration of his 70th birthday was canceled because of the war. In June 1917, he entered a sanatorium for the last time and continually wrote to his wife asking to be allowed to go home. Georg Cantor had a fatal heart attack on January 6, 1918, in the sanatorium where he had spent the last year of his life.

input: On January 6, 2009, CNN announced that Gupta had been considered for the position of Surgeon General by President Barack Obama.  Some doctors said that his communication skills and high profile would allow him to highlight medical issues and prioritize medical reform. However, others raised concerns about potential conflicts of interest with drug companies who have sponsored his broadcasts and his lack of skepticism in weighing the costs and benefits of medical treatments.  Representative John Conyers, Jr. (D-MI), wrote a letter opposing Gupta's nomination. Conyers supports a single-payer health care system, the sort that Conyers' filmmaker friend Michael Moore advocated in his documentary Sicko; Gupta has criticized Moore and the film.  Others, such as liberal commentator Jane Hamsher, defended the appointment, noting that Gupta's responsibilities as a surgeon general would be not that different from those of his CNN position, and that Gupta's media presence would make him ideal for the position. From the medical community, Donna Wright, of Creative Health Care Management, a regular commentator on medicine and politics, also defended the appointment on the grounds of his media presence, combined with his medical qualifications, which she viewed as an ideal combination for the post of surgeon general. Likewise, Fred Sanfilippo, executive vice president for health affairs at Emory University, supported Gupta's nomination by issuing a press release saying: "He has the character, training, intelligence and communications skills needed to help the United States improve its health and health care delivery systems in the next Administration." The American Council on Exercise, listed by PR Newswire as "America's leading authority on fitness and one of the largest fitness certification, education and training organizations in the world", endorsed the nomination of Gupta "because of his passion for inspiring Americans to lead healthier, more active lives". The ACE sent a letter of support to senator Edward M. Kennedy. Former surgeon general Joycelyn Elders also supported Gupta's nomination, saying: "He has enough well-trained, well-qualified public health people to teach him the things he needs to do the job." In March 2009 Gupta withdrew his name from consideration for the post, citing his family and his career.
