Problem: Daniel Barenboim (born 15 November 1942) is an Argentine-Israeli pianist and conductor who is a citizen of Argentina, Israel, Palestine, and Spain. He is the general music director of the Berlin State Opera, and the Staatskapelle Berlin; he previously served as Music Director of the Chicago Symphony Orchestra, the Orchestre de Paris and La Scala in Milan. Barenboim is known for his work with the West-Eastern Divan Orchestra, a Seville-based orchestra of young Arab and Israeli musicians, and as a resolute critic of the Israeli occupation of Palestinian territories. Barenboim has received many awards and prizes, including an honorary Knight Commander of the Order of the British Empire, France's Legion d'honneur both as a Commander and Grand Officier, and the German Grosses Bundesverdienstkreuz and Willy Brandt Award.

Daniel Barenboim was born in 1942 in Buenos Aires, Argentina, to Argentinian-Jewish parents Aida (nee Schuster) and Enrique Barenboim. He started piano lessons at the age of five with his mother, continuing to study with his father, who remained his only teacher. On 19 August 1950, at the age of seven, he gave his first formal concert in his hometown, Buenos Aires.  In 1952, Barenboim's family moved to Israel. Two years later, in the summer of 1954, his parents took him to Salzburg to take part in Igor Markevitch's conducting classes. During that summer he also met and played for Wilhelm Furtwangler, who has remained a central musical influence and ideal for Barenboim. Furtwangler called the young Barenboim a "phenomenon" and invited him to perform the Beethoven First Piano Concerto with the Berlin Philharmonic, but Barenboim's father considered it too soon after the Second World War for a child of Jewish parents to be performing in Berlin. In 1955 Barenboim studied harmony and composition with Nadia Boulanger in Paris.  On 15 June 1967, Barenboim and British cellist Jacqueline du Pre were married in Jerusalem at a Western Wall ceremony, Du Pre having converted to Judaism. Acting as one of the witnesses was the conductor Zubin Mehta, a long-time friend of Barenboim. Since "I was not Jewish I had to temporarily be renamed Moshe Cohen, which made me a 'kosher witness'," Mehta recalled. Du Pre retired from music in 1973, after being diagnosed with multiple sclerosis (MS). The marriage lasted until du Pre's death in 1987.  In the early 1980s, Barenboim began an affair with the Russian pianist Elena Bashkirova, with whom he had two sons born in Paris before du Pre's death: David Arthur, born 1983, and Michael, born 1985. Barenboim worked to keep his relationship with Bashkirova hidden from du Pre, and believed he had succeeded. He and Bashkirova married in 1988. Both sons are part of the music world: David is a manager-writer for the German hip-hop band Level 8, and Michael Barenboim is a classical violinist.

Did he do anything relevant in Israel?

Question:
Schlessinger was born in the New York City borough of Brooklyn. She was raised in Brooklyn and later on Long Island. Her parents were Monroe "Monty" Schlessinger, a civil engineer, and Yolanda (nee Ceccovini) Schlessinger, an Italian Catholic war bride. Schlessinger has said her father was charming and her mother beautiful as a young woman.
Schlessinger met and married Michael F. Rudolph, a dentist, in 1972 while she was attending Columbia University. The couple had a Unitarian ceremony. Separating from Rudolph, Schlessinger moved to Encino, California in 1975 when she obtained a job in the science department at the University of Southern California. Their divorce was finalized in 1977.  In 1975, while working in the labs at USC, she met Lewis G. Bishop, a professor of neurophysiology who was married and the father of three children. Bishop separated from his wife and began living with Schlessinger the same year. Speaking as one who went through and has personal experience with the social problems associated with such lifestyle choices, Schlessinger has vociferously proclaimed her disapproval of unwed couples "shacking up" and having children out of wedlock, helping others to not make the bad choices in the first place. According to her friend Shelly Herman, "Laura lived with Lew for about nine years before she was married to him." "His divorce was final in 1979. Bishop and Schlessinger married in 1985. Herman says that Schlessinger told her she was pregnant at the time, which Herman recalls as "particularly joyful because of the happy news." Schlessinger's only child, a son named Deryk, was born in November 1985.  Schlessinger's husband, Lewis G. Bishop, died November 2, 2015, after being ill for 1.5 years.  Schlessinger was estranged from her sister for years, and many thought she was an only child. She had not spoken to her mother for 18 to 20 years before her mother's death in 2002 from heart disease. Her mother's remains were found in her Beverly Hills condo approximately two months after she died, and lay unclaimed for some time in the Los Angeles morgue before Schlessinger had them picked up for burial. Concerning the day that she heard about her mother's death, she said: "Apparently she had no friends and none of her neighbors were close, so nobody even noticed! How sad." In 2006, Schlessinger wrote that she had been attacked in a "vulgar, inhumane manner by media types" because of the circumstances surrounding her mother's death, and that false allegations had been made that she was unfit to dispense advice based on family values. She said that she had not mourned the deaths of either of her parents because she had no emotional bond to them.
