Problem: Richard "Red" Skelton (July 18, 1913 - September 17, 1997) was an American comedy entertainer. He was best known for his national radio and television acts between 1937 and 1971, and as host of the television program The Red Skelton Show. He has stars on the Hollywood Walk of Fame for his work in radio and television, and also appeared in burlesque, vaudeville, films, nightclubs, and casinos, all while he pursued an entirely separate career as an artist. Skelton began developing his comedic and pantomime skills from the age of 10, when he became part of a traveling medicine show.

Skelton and Edna worked for a year in Camden, New Jersey, and were able to get an engagement at Montreal's Lido Club in 1934 through a friend who managed the chorus lines at New York's Roxy Theatre. Despite an initial rocky start, the act was a success, and brought them more theater dates throughout Canada. Skelton's performances in Canada led to new opportunities and the inspiration for a new, innovative routine that brought him recognition in the years to come. While performing in Montreal, the Skeltons met Harry Anger, a vaudeville producer for New York City's Loew's State Theatre. Anger promised the pair a booking as a headlining act at Loew's, but they would need to come up with new material for the engagement. While the Skeltons were having breakfast in a Montreal diner, Edna had an idea for a new routine as she and Skelton observed the other patrons eating doughnuts and drinking coffee. They devised the "Doughnut Dunkers" routine, with Skelton's visual impressions of how different people ate doughnuts. The skit won them the Loew's State engagement and a handsome fee. The couple viewed the Loew's State engagement in 1937 as Skelton's big chance. They hired New York comedy writers to prepare material for the engagement, believing they needed more sophisticated jokes and skits than the routines Skelton normally performed. However, his New York audience did not laugh or applaud until Skelton abandoned the newly written material and began performing the "Doughnut Dunkers" and his older routines. The doughnut-dunking routine also helped Skelton rise to celebrity status. In 1937, while he was entertaining at the Capitol Theater in Washington, D.C., President Franklin D. Roosevelt invited Skelton to perform at a White House luncheon. During one of the official toasts, Skelton grabbed Roosevelt's glass, saying, "Careful what you drink, Mr. President. I got rolled in a place like this once." His humor appealed to FDR and Skelton became the master of ceremonies for Roosevelt's official birthday celebration for many years afterward.

Question:
Karlheinz Stockhausen (German: [kaRl'haInts 'StokhaUzn]; 22 August 1928 - 5 December 2007) was a German composer, widely acknowledged by critics as one of the most important (Barrett 1988, 45; Harvey 1975b, 705; Hopkins 1972, 33; Klein 1968, 117) but also controversial (Power 1990, 30) composers of the 20th and early 21st centuries. A critic calls him "one of the great visionaries of 20th-century music" (Hewett 2007). He is known for his groundbreaking work in electronic music, for introducing controlled chance (aleatory techniques or aleatoric musical techniques) into serial composition, and for musical spatialization.
On 29 December 1951, in Hamburg, Stockhausen married Doris Andreae (Kurtz 1992, 45; Maconie 2005, 47). Together they had four children: Suja (b. 1953), Christel (b. 1956), Markus (b. 1957), and Majella (b. 1961) (Kurtz 1992, 90; Tannenbaum 1987, 94). They were divorced in 1965 (Rathert 2013). On 3 April 1967, in San Francisco, he married Mary Bauermeister, with whom he had two children: Julika (b. 22 January 1966) and Simon (b. 1967) (Kurtz 1992, 141, 149; Tannenbaum 1987, 95). They were divorced in 1972 (Rathert 2013; Stockhausen-Stiftung & [2013]). Four of Stockhausen's children became professional musicians (Kurtz 1992, 202), and he composed some of his works specifically for them. A large number of pieces for the trumpet--from Sirius (1975-77) to the trumpet version of In Freundschaft (1997)--were composed for and premiered by his son Markus (Kurtz 1992, 208; M. Stockhausen 1998, 13-16; Tannenbaum 1987, 61). Markus, at the age of 4 years, had performed the part of The Child in the Cologne premiere of Originale, alternating performances with his sister Christel (Maconie 2005, 220). Klavierstuck XII and Klavierstuck XIII (and their versions as scenes from the operas Donnerstag aus Licht and Samstag aus Licht) were written for his daughter Majella, and were first performed by her at the ages of 16 and 20, respectively (Maconie 2005, 430, 443; Stockhausen Texte, 5:190, 255, 274; Stockhausen Texte, 6:64, 373). The saxophone duet in the second act of Donnerstag aus Licht, and a number of synthesizer parts in the Licht operas, including Klavierstuck XV ("Synthi-Fou") from Dienstag, were composed for his son Simon (Kurtz 1992, 222; Maconie 2005, 480, 489; Stockhausen Texte, 5:186, 529), who also assisted his father in the production of the electronic music from Freitag aus Licht. His daughter Christel is a flautist who performed and gave a course on interpretation of Tierkreis in 1977 (Stockhausen Texte, 5:105), later published as an article (C. Stockhausen 1978). In 1961, Stockhausen acquired a parcel of land in the vicinity of Kurten, a village east of Cologne, near Bergisch Gladbach in the Bergisches Land. He had a house built there, which was designed to his specifications by the architect Erich Schneider-Wessling, and he resided there from its completion in the autumn of 1965 (Kurtz 1992, 116-17, 137-38).
