Question:
Williams was born on April 5, 1973, in Virginia Beach, Virginia, the oldest of three sons of Pharaoh Williams, a handyman, and his wife Carolyn, a teacher. His roots extend for generations in Virginia and North Carolina, and one of his ancestors journeyed to West Africa in 1831, prompting other relatives to emigrate from America to Liberia in 1832. He met Chad Hugo in a seventh-grade summer band camp where Williams played the keyboards and drums and Hugo played tenor saxophone. They were also both members of a marching band; Williams played the snare drum while Hugo was drum major.
On March 31, 2014, Williams was announced as a new coach for the seventh season of The Voice, replacing CeeLo Green. On May 18, 2015, Team Pharrell had 16-year-old Sawyer Fredericks win the eighth season of The Voice. In June 2014, it was announced that Williams would make a guest appearance on the docu-series Sisterhood of Hip Hop. Williams was the executive producer of Atlanta rapper T.I.'s ninth studio album, Paperwork, which was released on October 21, 2014 by Grand Hustle and Columbia Records. In May 2014, Williams curated an art show named after his album, "Girl," at the Galerie Perrotin in Paris, France. The show included 37 artists including Takashi Murakami, JR, Daniel Arsham, and Marina Abramovic among others." Comme des Garcons developed a unisex fragrance with Williams scheduled for release in late 2014. Kaws designed the bottle artwork.  In January 2015, Williams and Al Gore announced that they are teaming up to create a 7-continent "Live Earth" concert on June 18 to raise awareness about and pressure governments to act on climate change. He is the musical director. On February 8, 2015, Williams made a cameo in an episode of The Simpsons entitled "Walking Big & Tall" where he comes to Springfield to write a new anthem for the town. Williams recorded three songs for the soundtrack to the animated film The SpongeBob Movie: Sponge Out of Water. He also recorded a song "Shine" with Gwen Stefani for the Paddington movie. At the 2015 Grammy Awards Williams performed an orchestral rendition of "Happy" with composer Hans Zimmer and pianist Lang Lang that included a tribute to the Black Lives Matter "Hands Up, Don't Shoot" movement inspired by Eric Garner's death and the events in Ferguson, Missouri. In 2015, a unanimous jury determined that Williams's 2013 hit song "Blurred Lines" was an infringement of the 1977 Marvin Gaye song "Got to Give It Up". The jury awarded the Gaye family $7.4 million in damages for the copyright infringement based on profits generated.  In October 2015, the Tisch School of the Arts at New York University named Williams as their artist-in-residence. He gave the 2017 commencement address at NYU and received an honorary degree on May 17, 2017.  Also in October 2015, Williams announced that he will perform with a gospel choir on Sunday, November 1, at Emanuel AME Church in Charleston, South Carolina, where nine black parishioners were shot and killed on June 17, allegedly by a young white man who is awaiting trial. This is part of a program on race relations being produced by A+E Networks and iHeartMedia. Williams plans to speak with community leaders and others affected by the shooting, which dominated the U.S. news media for several days. The two-hour Shining a Light: A Concert for Progress on Race in America program is scheduled to air November 20, and will also feature a concert to be filmed November 18 in Los Angeles. A goal of the program is to raise money for the victims of racial violence and for organizations around the country working to promote racial equity.

Question:
Josef Mengele (German: ['jo:zef 'meNG@l@]; 16 March 1911 - 7 February 1979) was a German Schutzstaffel (SS) officer and physician in Auschwitz concentration camp during World War II. Mengele was a member of the team of doctors responsible for the selection of victims to be killed in the gas chambers and for performing deadly human experiments on prisoners.
In May 1960, Isser Harel, director of Mossad (the Israeli intelligence agency), personally led the successful effort to capture Adolf Eichmann in Buenos Aires. He hoped to track down Mengele as well so he too could be brought to trial in Israel. Under interrogation, Eichmann provided the address of a boarding house that had been used as a safe house for Nazi fugitives. Surveillance of the house did not reveal Mengele or any members of his family, and the neighborhood postman said that although Mengele had recently been receiving letters there under his real name, he had since relocated, leaving no forwarding address. Harel's inquiries at a machine shop where Mengele had been part owner did not turn up any leads either, so he had to give up.  In spite of having provided Mengele with legal documents in his real name in 1956, thus enabling him to regularize his residency in Argentina, West Germany offered a reward for his capture. Ongoing newspaper coverage of his wartime activities (accompanied by photographs of the fugitive) led Mengele to relocate again in 1960. Former pilot Hans-Ulrich Rudel put him in touch with the Nazi supporter Wolfgang Gerhard, who helped Mengele get across the border into Brazil. He stayed with Gerhard on his farm near Sao Paulo until more permanent accommodation was found with Hungarian expatriates Geza and Gitta Stammer. Helped by an investment from Mengele, the couple bought a farm in Nova Europa, and Mengele was given the job of manager. In 1962 the three bought a coffee and cattle farm in Serra Negra, with Mengele owning a half interest. Initially, Gerhard told the couple that Mengele's name was "Peter Hochbichler", but they discovered his true identity in 1963. Gerhard convinced them not to report Mengele's location to the authorities, saying they could themselves get in trouble for harboring the fugitive. West Germany, tipped off to the possibility that Mengele had relocated there, widened its extradition request to include Brazil in February 1961.  Meanwhile, Zvi Aharoni, one of the Mossad agents who had been involved in the Eichmann capture, was placed in charge of a team of agents tasked with locating Mengele and bringing him to trial in Israel. Inquiries in Paraguay gave no clues as to his whereabouts, and they were unable to intercept any correspondence between Mengele and his wife Martha, then living in Italy. Agents following Rudel's movements did not produce any leads. Aharoni and his team followed Gerhard to a rural area near Sao Paulo, where they located a European man believed to be Mengele. Aharoni reported his findings to Harel, but the logistics of staging a capture, budgetary constraints, and the need to focus on the nation's deteriorating relationship with Egypt led the Mossad chief to call a halt to the operation in 1962.
