Problem: Ahmet Ertegun (, Turkish spelling: Ahmet Ertegun ([ah'met erte'jyn]); (July 31 [O.S. 18 July] 1923 - December 14, 2006) was a Turkish-American businessman, songwriter and philanthropist. He was best known as the co-founder and president of Atlantic Records, and for discovering and championing many leading rhythm and blues and rock musicians. He also wrote classic blues and pop songs, and served as the chairman of the Rock and Roll Hall of Fame and museum, located in Cleveland, Ohio. Ertegun has been described as "one of the most significant figures in the modern recording industry."

A memorial service for Ertegun was held in New York on April 17, 2007. A large part of the evening was given over to musical performances. Wynton Marsalis opened the tribute with the jazz standard "Didn't He Ramble", Eric Clapton and Dr. John performed "Drinkin' Wine Spo-Dee-O-Dee", and other performers included Solomon Burke, Ben E. King, Sam Moore, Stevie Nicks, Crosby, Stills, Nash & Young, and Phil Collins.  Another informal salute to him took place in Los Angeles on July 31, 2007, the anniversary of his birth. The tribute took place at Grauman's Egyptian Theatre in Hollywood. Several of his friends shared anecdotes about their experiences with him and the assembled gathering then saw a special screening of the American Masters documentary Atlantic Records: The House That Ahmet Built. Among those who paid tribute to Ertegun in person were: Solomon Burke, Jerry Leiber & Mike Stoller, Keith Emerson, Peter Asher, Spencer Davis, the film's producer (and longtime friend) Phil Carson, Taylor Hackford and event producer Martin Lewis. Yusuf Islam, formerly known as Cat Stevens, came to America after a 20-year hiatus to attend the ceremonies.  The Martin Scorsese film "Shine a Light" about The Rolling Stones concert held at the Beacon Theatre in New York contains a dedication to Ertegun and Andrea Corr's solo album Ten Feet High is dedicated "To the memory of Ahmet Ertegun".  In honor of the barriers the Ertegun brothers broke during their time in segregated Washington, the current Turkish Ambassador to the U.S., Namik Tan, hosts a series of jazz concerts at the historical residence on Sheridan Circle in Washington, D.C. The "Ertegun Jazz Series," in collaboration with Jazz at Lincoln Center, revives the brothers' legacy of bridging cultures and bringing people together with one common objective: celebrating music. In that same spirit, Ambassador Tan is opening the doors of his home to residents of D.C. from various backgrounds - Members of Congress, Administration officials, academia, the media, business leaders, and others.

Answer with quotes: A memorial service for Ertegun was held in New York on April 17, 2007.

Background: Sean John Combs was born on November 4, 1969 in Manhattan's Harlem neighborhood in New York City, and was raised in Mount Vernon, New York. His mother, Janice (Smalls), was a model and teacher's assistant, and his father, Melvin Earl Combs, served in the U.S. Air Force and was an associate of convicted New York drug dealer Frank Lucas. At age 33, Melvin was shot to death while sitting in his car on Central Park West, when Combs was 2 years old. Combs graduated from the Roman Catholic Mount Saint Michael Academy in 1987.
Context: In 1998, Combs started a clothing line, Sean John. It was nominated for the Council of Fashion Designers of America (CFDA) award for Menswear Designer of the Year in 2000, and won in 2004. California billionaire Ronald Burkle invested $100 million into the company in 2003.  Also in 2003, the National Labor Committee revealed that factories producing the clothing in Honduras were violating Honduran labor laws. Among the accusations were that workers were subjected to body searches and involuntary pregnancy tests. Bathrooms were locked and access tightly controlled. Employees were forced to work overtime and were paid sweatshop wages. Charles Kernaghan of the National Labor Committee told The New York Times that "Sean Puff Daddy obviously has a lot of clout, he can literally do a lot overnight to help these workers."  Combs responded with an extensive investigation, telling reporters "I'm as pro-worker as they get". On February 14, 2004, Kernaghan announced that improvements had been implemented at the factory, including adding air conditioning and water purification systems, firing the most abusive supervisors, and allowing the formation of a labor union. In late 2006, the department store Macy's removed Sean John jackets from their shelves when they discovered that the clothing was made using raccoon dog fur. Combs had not known the jackets were made with dog fur, but as soon as he was alerted, he had production stopped.  In November 2008, Combs added a men's perfume called "I Am King" to the Sean John brand. The fragrance, dedicated to Barack Obama, Muhammad Ali, and Martin Luther King, featured model Bar Refaeli in its advertisements. In early 2016, Sean John introduced the brand's GIRLS collection.
Question: did anyone work with him?

Question:
Born in Dusseldorf, West Germany, Kaymer turned professional at age 20 in 2005 and is a member of the European Tour. He has won eleven tournaments on the tour including four in 2010 to win for the first time the Race to Dubai, formerly the Order of Merit. Among those wins was the PGA Championship in the United States, which made him only the second German (after Bernhard Langer) to win a major championship. He also won the WGC-HSBC Champions to become the tenth player to win both a major title and a World Golf Championship event.
Entering the 2011 season, Kaymer turned down a chance to become a full PGA Tour member; he had gained exempt status with his win in the PGA Championship. He stated he would concentrate on the European Tour for 2011, but would play several U.S. events as well.  In January, Kaymer claimed his third Abu Dhabi HSBC Golf Championship title in four years and displaced Tiger Woods as number two in the world rankings.  After his runner-up finish at the 2011 WGC-Accenture Match Play Championship, Kaymer overtook Lee Westwood as the number one golfer in the world, making him only the second German (after Bernhard Langer) to be the top-ranked golfer in the world. At the time he was the second youngest to reach world number one behind Tiger Woods, soon surpassed by Rory McIlroy in March 2012, who gained the top ranking at age 22. In April, he relinquished his number one ranking after eight weeks to Westwood, who won the Indonesian Masters.  After reaching the number one ranking, Kaymer decided to undergo a swing change to be able to move the ball both ways. Frustrated with his disappointing results at the Masters, Kaymer looked to better shape a draw, a shot he thought he needed to be able to contend at Augusta. Kaymer missed the cut at the Masters for the fourth time in 2011 and later admitted that changing his swing for Augusta was a "big mistake." The rest of 2011 was relatively inconsistent for Kaymer.  In November 2011, Kaymer won his first WGC title at the WGC-HSBC Champions event in Shanghai, China. He entered the final round trailing Fredrik Jacobson by five strokes, then shot a final round 9-under 63 to take the title by three strokes from Jacobson. After parring his opening six holes, Kaymer birdied nine of the remaining twelve, with four straight birdies at the start of the back nine. This was the biggest comeback win ever in the history of the WGC events, and the lowest final round by a WGC winner, topping a 64 set by Hunter Mahan in 2010. Kaymer became the tenth player to have won both a major and a WGC event, and the win took him back to world number four.
