Problem: Background: Terence Steven McQueen was born on March 24, 1930, at St. Francis Hospital in Beech Grove, Indiana, a suburb of Indianapolis. His father, William Terence McQueen, was a stunt pilot for a barnstorming flying circus who left McQueen's mother, Julia Ann (a.k.a. Julian; nee Crawford), six months after meeting her. Several biographers have stated that Julia Ann was an alcoholic.
Context: The blue-tinted sunglasses (Persol 714) worn by McQueen in the 1968 movie The Thomas Crown Affair sold at a Bonhams & Butterfields auction in Los Angeles for $70,200 in 2006. One of his motorcycles, a 1937 Crocker, sold for a world-record price of $276,500 at the same auction. McQueen's 1963 metallic-brown Ferrari 250 GT Lusso Berlinetta sold for US$2.31 million at auction on August 16, 2007. Except for three motorcycles sold with other memorabilia in 2006, most of McQueen's collection of 130 motorcycles was sold four years after his death. The 1970 Porsche 911S purchased while making the film Le Mans and appearing in the opening sequence was sold at auction in August 2011 for $1.375 million. The Rolex Explorer II, Reference 1655, known as Rolex Steve McQueen in the horology collectors' world, the Rolex Submariner, Reference 5512, which McQueen was often photographed wearing in private moments, sold for $234,000 at auction on June 11, 2009, a world-record price for the reference. McQueen was left-handed and wore the watch on his right wrist. From 1995 to 2011, McQueen's red 1957 Chevrolet fuel-injected convertible was displayed at the Petersen Automotive Museum in Los Angeles in a special Cars of Steve McQueen exhibit. It is now in the collection of actress Ruth Buzzi and her husband Kent Perkins. McQueen was a sponsored ambassador for Heuer watches. In the 1970 film Le Mans, he famously wore a blue-faced Monaco 1133B Caliber 11 Automatic, which led to its cult status among watch collectors. His sold for $87,600 at auction on June 11, 2009. Tag Heuer continues to promote its Monaco range with McQueen's image. From 2009, Triumph Motorcycles Ltd, licensed by his estate, marketed a line of clothing inspired by McQueen's association with their brand, particularly his 1964 ISDT participation. British heritage clothing brand J. Barbour and Sons created a Steve McQueen collection, based on his ownership of a Barbour International motorbike jacket. Steve McQueen was the second album by English pop band Prefab Sprout, which was released in June 1985. It was released in the United States under the title Two Wheels Good due to a legal conflict with McQueen's estate.

Problem: Background: William James Dixon (July 1, 1915 - January 29, 1992) was an American blues musician, vocalist, songwriter, arranger and record producer. He was proficient in playing both the upright bass and the guitar and was a capable singer, but he is perhaps best known as one of the most prolific songwriters of his time. Next to Muddy Waters, Dixon is recognized as the most influential person in shaping the post-World War II sound of the Chicago blues. Dixon's songs have been recorded by countless musicians in many genres as well as by various ensembles in which he participated.
Context: Dixon signed with Chess Records as a recording artist, but he began performing less, being more involved with administrative tasks for the label. By 1951, he was a full-time employee at Chess, where he acted as producer, talent scout, session musician and staff songwriter. He was also a producer for the Chess subsidiary Checker Records. His relationship with Chess was sometimes strained, but he stayed with the label from 1948 to the early 1960s. During this time Dixon's output and influence were prodigious. From late 1956 to early 1959, he worked in a similar capacity for Cobra Records, for which he produced early singles for Otis Rush, Magic Sam, and Buddy Guy. He later recorded for Bluesville Records. From the late 1960s until the mid-1970s, Dixon ran his own record label, Yambo Records, and two subsidiary labels, Supreme and Spoonful. He released his 1971 album, Peace?, on Yambo and also singles by McKinley Mitchell, Lucky Peterson and others. Dixon is considered one of the key figures in the creation of Chicago blues. He worked with Chuck Berry, Muddy Waters, Howlin' Wolf, Otis Rush, Bo Diddley, Joe Louis Walker, Little Walter, Sonny Boy Williamson, Koko Taylor, Little Milton, Eddie Boyd, Jimmy Witherspoon, Lowell Fulson, Willie Mabon, Memphis Slim, Washboard Sam, Jimmy Rogers, Sam Lay and others. In December 1964, the Rolling Stones reached number one on the UK Singles Chart with their cover of Dixon's "Little Red Rooster". In the same year, the group also covered "I Just Want To Make Love To You" on their debut album, The Rolling Stones.
Question: what kind of work was he doing at the height of his career?

Dixon is considered one of the key figures in the creation of Chicago blues.
