Background: Roger Federer (German pronunciation: ['rodZ@r 'fe:d@r@r]; born 8 August 1981) is a Swiss professional tennis player who is currently ranked world No. 2 in men's singles tennis by the Association of Tennis Professionals (ATP). He is regarded by many fans, players and analysts as the greatest tennis player of all time. Federer has won 20 Grand Slam singles titles--the most in history for a male player--and has held the world No. 1 spot in the ATP rankings for a record total of 308 weeks, including 237 consecutive weeks. After turning professional in 1998, he was continuously ranked in the top ten from October 2002 to November 2016.
Context: Federer entered the top 100 ranking for the first time on 20 September 1999 and started at the 1999 Marseille Open defeating the reigning champion of the 1998 French Open, Spaniard Carlos Moya. His first final came at the Marseille Open in 2000, where he lost to fellow Swiss Marc Rosset. Federer won the 2001 Hopman Cup representing Switzerland, along with Martina Hingis. The duo defeated the American pair of Monica Seles and Jan-Michael Gambill in the finals. Federer would later say that his experience with Hingis "definitely helped me to become the player I am today." Federer's first singles win was at the 2001 Milan Indoor tournament, where he defeated Julien Boutter in the final. Although he won his first title already in 1999 on the Challenger tour, winning the doubles event in Segovia, Spain with Dutchman Sander Groen, the final was played on Federer's 18th birthday. In 2001, Federer made his first Grand Slam quarterfinal at the French Open, losing to former world No. 2 and eventual finalist Alex Corretja. His run to the French quarterfinals launched him into the top 15 for the first time in his career. His international breakthrough came at the 2001 Wimbledon Championships, where a 19-year-old Federer faced the four-time defending champion and all-time Grand Slam leader Pete Sampras. The teenage Swiss stunned the seven-time Wimbledon champion and No. 1 seed in a dramatic five-set epic to reach the quarterfinals. In the quarters he faced Englishman Tim Henman, eventually losing in an overtime fourth-set tiebreaker. Federer's breakthrough at Wimbledon signaled the record-breaking dominance he would display at the All England Club over the next two decades. The first final he reached at the prestigious Masters level came at the 2002 Miami Masters event, where he lost to former and future world No. 1 Andre Agassi on hard court. Federer won his first Master Series event at the 2002 Hamburg Masters on clay, over Marat Safin; the victory put him in top 10 for the first time. Federer made 10 singles finals between 1998 and 2002, of which he won four and lost six. He also made six finals in doubles. Of note are Federer and partner Max Mirnyi's defeat in the final of the Indian Wells Masters in 2002, and their victory in the same year in the final of the Rotterdam 500 series event. Federer had won the latter a year earlier with partner Jonas Bjorkman. He finished 2001 with an ATP ranking of No. 13, and 2002 was the first year he was ranked within the top 10, finishing at No. 6.

Question:
The Vienna Boys' Choir (German: Wiener Sangerknaben) or Vienna Choir Boys is a choir of boy sopranos and altos based in Vienna, Austria. It is one of the best known boys' choirs in the world. The boys are selected mainly from Austria, but also from many other countries. The choir is a private, not-for-profit organization.
The choir is the modern-day descendant of the boys' choirs of the Viennese Court, dating back to the late Middle Ages. The choir was, for practical purposes, established by a letter from Emperor Maximilian I of Habsburg on 30 June 1498, instructing court officials to employ a singing master, two basses and six boys. Jurij Slatkonja became the director of the ensemble. The role of the choir (numbering between 24 and 26) was to provide musical accompaniment for the church mass. Additionally, the Haydn brothers were members of the St. Stephen's Cathedral choir, directed at the time by Georg Reutter II, who used this choir in his duties for the imperial court, which at the time had no boy choristers of its own. Over the centuries, the choir has worked with many composers, including Heinrich Isaac, Hofhaimer, Biber, Fux, Caldara, Gluck, Salieri, Mozart, Franz Schubert and Bruckner. In 1920, following the fall of the Austrian Empire, the Hofkapelle (court orchestra) was disbanded. However, the rector at the time, Josef Schnitt, sought a continuation of the tradition. In 1924, the Vienna Boys' Choir was officially founded, and it has evolved into a professional music group. The choir adopted the now-famous blue and white sailor suit, replacing the imperial military cadet uniform that included a dagger. The composer HK Gruber is one of the graduates of the reformed choir. Since 1948, the Palais Augarten has served as their rehearsal venue and boarding school, which goes from kindergarten level up to middle school level. In 1961, Walt Disney filmed Almost Angels, a fictional drama about (and starring) the Vienna Boys' Choir, set and filmed in the Palais Augarten. It was Disney who, for cinematographic reasons, persuaded the Austrian government to allow the boys to legally wear the Austrian national emblem on the breast of their uniform, a tradition that continues to this day.

Who was the singing master?

Answer:

Problem: Background: Thomas Nast (; German: [nast]; September 27, 1840 - December 7, 1902) was a German-born American caricaturist and editorial cartoonist considered to be the "Father of the American Cartoon". He was the scourge of Democratic Representative "Boss" Tweed and the Tammany Hall Democratic party political machine.
Context: In 1890, Nast published Thomas Nast's Christmas Drawings for the Human Race. He contributed cartoons in various publications, notably the Illustrated American, but was unable to regain his earlier popularity. His mode of cartooning had come to be seen as outdated, and a more relaxed style exemplified by the work of Joseph Keppler was in vogue. Health problems, which included pain in his hands which had troubled him since the 1870s, affected his ability to work. In 1892, he took control of a failing magazine, the New York Gazette, and renamed it Nast's Weekly. Now returned to the Republican fold, Nast used the Weekly as a vehicle for his cartoons supporting Benjamin Harrison for president. The magazine had little impact and ceased publication seven months after it began, shortly after Harrison's defeat. The failure of Nast's Weekly left Nast with few financial resources. He received a few commissions for oil paintings and drew book illustrations. In 1902, he applied for a job in the State Department, hoping to secure a consular position in western Europe. Although no such position was available, President Theodore Roosevelt was an admirer of the artist and offered him an appointment as the United States' Consul General to Guayaquil, Ecuador in South America. Nast accepted the position and traveled to Ecuador on July 1, 1902. During a subsequent yellow fever outbreak, Nast remained on the job, helping numerous diplomatic missions and businesses escape the contagion. He contracted the disease and died on December 7 of that year. His body was returned to the United States, where he was interred in the Woodlawn Cemetery in The Bronx, New York City.
Question: When did he stop Harpers weekly?
