Problem: Arthur Asher Miller (October 17, 1915 - February 10, 2005) was an American playwright, essayist, and figure in twentieth-century American theater. Among his most popular plays are All My Sons (1947), Death of a Salesman (1949), The Crucible (1953) and A View from the Bridge (1955, revised 1956). He also wrote several screenplays and was most noted for his work on The Misfits (1961). The drama Death of a Salesman has been numbered on the short list of finest American plays in the 20th century alongside Eugene O'Neill's Long Day's Journey into Night and Tennessee Williams's A Streetcar Named Desire.

In 1940, Miller married Mary Grace Slattery. The couple had two children, Jane and Robert (born May 31, 1947). Miller was exempted from military service during World War II because of a high school football injury to his left kneecap. That same year his first play was produced; The Man Who Had All the Luck won the Theatre Guild's National Award. The play closed after four performances with disastrous reviews.  In 1947, Miller's play All My Sons, the writing of which had commenced in 1941, was a success on Broadway (earning him his first Tony Award, for Best Author) and his reputation as a playwright was established. Years later, in a 1994 interview with Ron Rifkin, Miller said that most contemporary critics regarded All My Sons as "a very depressing play in a time of great optimism" and that positive reviews from Brooks Atkinson of The New York Times had saved it from failure.  In 1948, Miller built a small studio in Roxbury, Connecticut. There, in less than a day, he wrote Act I of Death of a Salesman. Within six weeks, he completed the rest of the play, one of the classics of world theater. Death of a Salesman premiered on Broadway on February 10, 1949, at the Morosco Theatre, directed by Elia Kazan, and starring Lee J. Cobb as Willy Loman, Mildred Dunnock as Linda, Arthur Kennedy as Biff, and Cameron Mitchell as Happy. The play was commercially successful and critically acclaimed, winning a Tony Award for Best Author, the New York Drama Circle Critics' Award, and the Pulitzer Prize for Drama. It was the first play to win all three of these major awards. The play was performed 742 times.  In 1949, Miller exchanged letters with Eugene O'Neill regarding Miller's production of All My Sons. O'Neill had sent Miller a congratulatory telegram; in response, he wrote a letter that consisted of a few paragraphs detailing his gratitude for the telegram, apologizing for not responding earlier, and inviting Eugene to the opening of Death of a Salesman. O'Neill replied, accepting the apology, but declining the invitation, explaining that his Parkinson's disease made it difficult to travel. He ended the letter with an invitation to Boston, a trip that never occurred.

Question:
John James 'Sean' Kelly (born 24 May 1956) is an Irish former professional road bicycle racer. He was one of the most successful road cyclists of the 1980s, and one of the finest classics riders of all time. From turning professional in 1977 until his retirement in 1994, he won nine monument classics, and 193 professional races in total. He won Paris-
Kelly's first professional race was the Etoile de Besseges. It started on 7 February 1977 and lasted six days. Kelly came 10th on the first day. The Flandria team was in two parts: the strongest riders, such as the world champion Freddy Maertens, were in the main section, based in Belgium. Kelly rode with the second section, based more in France because Flandria wanted to sell more of its mopeds, scooters and bicycles there. The strongest riders in both camps came together for big races. Kelly was recruited as a domestique for Maertens in the main team for year's Paris-Nice - shortly afterwards he won his first race, the opening stage of the Tour of Romandy - and stayed in it for the Tour de France, in which he also won a stage.  Kelly stayed with de Gribaldy for 1977 and 1978. Then in 1978 Michel Pollentier was disqualified from the Tour de France after cheating a drugs test on the afternoon that he took the race lead. He left the team at the end of the season and started his own, with a new backer, Splendor. Both Maertens and Pollentier wanted Kelly. Pollentier and Splendor offered Kelly more and made him a team leader. But Splendor was new and logistic problems became obvious. The bikes were in poor state - enough that Splendor decided not to ride Paris-Roubaix - and the manager, Robert Lauwers, was replaced. Kelly rose above it and rode for himself. The writer Robin Magowan said:  Some people can do business on the committee system; others find that life is only fun when you are running the show. In Kelly's case it was to mean working for the collection of underpaid has-beens that de Gribaldy habitually assembled. But a smaller, less pretentious team can have its advantages for a rider of Kelly's sort. When you don't have to compete for a team's loyalty you can concentrate on winning races, and that's exactly what Kelly proceeded to do.  In time the team improved. Kelly received few offers from elsewhere and Splendor matched those he did get. He was paid about PS30,000 plus bonuses in his last season. But strengthening the team had included bringing in another sprinter, Eddy Planckaert, and Kelly's role as a foreigner in the team was unclear. He heard that de Gribaldy was starting a new team and the two were reunited in 1982 at Sem-France Loire.
