Problem: Background: Povenmire was born in San Diego, California on September 18, 1963, and grew up in the city of Mobile, Alabama. A child prodigy, he began drawing at age two; by the time he was ten, his work was displayed in local art shows. His first efforts in animation included a series of flip books that he produced in his school text books. As a child, Povenmire considered animator Chuck Jones his hero; in a 2009 interview, he stated that "every drawing he [Jones] did was beautiful to look at and had so much energy in it".
Context: Povenmire later became a director on Family Guy, starting with the season two episode, "Road to Rhode Island". Creator Seth MacFarlane granted Povenmire substantial creative freedom. Povenmire recalled that MacFarlane would tell him "We've got two minutes to fill. Give me some visual gags. Do whatever you want. I trust you." Povenmire praised MacFarlane's management style for letting him "have [...] fun." Povenmire brought realism and material from his own experiences to the visual direction of Family Guy. For "One if By Clam, Two if By Sea" (August 1, 2001), several characters demonstrate Fosse-like moves in prison. To correctly depict the moves, Povenmire asked color artist Cynthia MacIntosh, who had been a professional dancer, to strike poses so he could properly illustrate the sequence. In the episode "To Love and Die in Dixie" (November 15, 2001), Povenmire drew on his childhood in the Deep South to create and sequence a background scene in which the redneck character nonchalantly kicks a corpse into the nearby river. "Brian Wallows and Peter's Swallows" (January 17, 2002), a Family Guy episode which Povenmire directed, won the Emmy Award for Best Song. Creator MacFarlane, the recipient of the award, noted that Povenmire deserved to have received the award for the contribution the visuals made to the episode's win. Povenmire jokingly responded "That's a nice sentiment and all, but did he offer to give me his? No! And it's not like he doesn't already have two of his own just sitting in his house!" Povenmire was nominated for an Annie Award for Directing in an Animated Television Production for the episode "PTV" (November 6, 2005) but lost out to a fellow Family Guy director Peter Shin, who had directed the episode "North by North Quahog". Povenmire and several others were also nominated for their work on "PTV" in the Outstanding Animated Program (for Programming Less Than One Hour) category at the Primetime Emmy Awards. Povenmire also received the same nomination for "Road to Rhode Island." During Family Guy's brief cancellation, Povenmire was offered a job as storyboard director of the series SpongeBob SquarePants. He wrote various musical numbers for the series, including "The Campfire Song Song" in "The Camping Episode" (April 3, 2004).
Question: Did he write the storyline for Family Guy?
Answer: Brian Wallows and Peter's Swallows" (January 17, 2002), a Family Guy episode which Povenmire directed, won the Emmy Award for Best Song.

Problem: Background: Georg Ferdinand Ludwig Philipp Cantor ( KAN-tor; German: ['geoRk 'feRdinant 'lu:tvIc 'fIlIp 'kantoR]; March 3 [O.S. February 19] 1845 - January 6, 1918) was a German mathematician. He invented set theory, which has become a fundamental theory in mathematics. Cantor established the importance of one-to-one correspondence between the members of two sets, defined infinite and well-ordered sets, and proved that the real numbers are more numerous than the natural numbers.
Context: 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.
Question: when did he retire
Answer:
Cantor retired in 1913, living in poverty and suffering from malnourishment during World War I.
