Scott Joplin (November 24, 1868 – April 1, 1917) was an American composer and pianist. Dubbed the "King of Ragtime", he composed more than 40 ragtime pieces, one ragtime ballet (original version of "The Ragtime Dance", 1899/1902), and two operas. One of his first and most popular pieces, the "Maple Leaf Rag", became the genre's first and most influential hit, later being recognized as the quintessential rag. Joplin considered ragtime to be a form of classical music meant to be played in concert halls and largely disdained the performance of ragtime as honky tonk music most common in saloons. Joplin grew up in a musical family of railway laborers in Texarkana, Texas. During the late 1880s, he traveled the American South as a musician. He went to Chicago for the World's Fair of 1893, which helped make ragtime a national craze by 1897. Joplin moved to Sedalia, Missouri, in 1894 and worked as a piano teacher. He began publishing music in 1895, and his "Maple Leaf Rag" in 1899 brought him fame and a steady income. In 1901, Joplin moved to St. Louis and two years later scored his first opera, A Guest of Honor. It was confiscated—along with his belongings—for non-payment of bills and is now considered lost. In 1907, Joplin moved to New York City to (unsuccessfully) find a producer for a new opera. In 1916, Joplin descended into dementia from neurosyphilis. His 1917 death marks the end of the ragtime era. Joplin's music was rediscovered and returned to popularity in the early 1970s with the release of a million-selling album recorded by Joshua Rifkin. This was followed by the Academy Award–winning 1973 film The Sting, which featured several of Joplin's compositions. Treemonisha, his second opera, was produced in 1972; and, in 1976, Joplin was awarded a Pulitzer Prize.

Elvis Aaron Presley (January 8, 1935 – August 16, 1977) was an American singer and actor. Referred to as the "King of Rock and Roll", he is widely regarded as one of the most culturally significant figures of the 20th century. Presley's energetic and sexually provocative performance style, combined with a mix of influences across color lines during a transformative era in race relations, brought both great success and initial controversy. Presley was born in Tupelo, Mississippi; his family moved to Memphis, Tennessee, when he was 13. He began his music career in 1954 at Sun Records with producer Sam Phillips, who wanted to bring the sound of African-American music to a wider audience. Presley, on guitar and accompanied by lead guitarist Scotty Moore and bassist Bill Black, was a pioneer of rockabilly, an uptempo, backbeat-driven fusion of country music and rhythm and blues. In 1955, drummer D. J. Fontana joined to complete the lineup of Presley's classic quartet and RCA Victor acquired his contract in a deal arranged by Colonel Tom Parker, who managed him for the rest of his career. Presley's first RCA Victor single, "Heartbreak Hotel", was released in January 1956 and became a number-one hit in the US. Within a year, RCA Victor sold ten million Presley singles. With a series of successful television appearances and chart-topping records, Presley became the leading figure of the newly popular rock and roll; though his performing style and promotion of the then-marginalized sound of African Americans led to him being widely considered a threat to the moral well-being of white American youth. In November 1956, Presley made his film debut in Love Me Tender. Drafted into military service in 1958, he relaunched his recording career two years later with some of his most commercially successful work. Presley held few concerts, and, guided by Parker, devoted much of the 1960s to making Hollywood films and soundtrack albums, most of them critically derided. Some of Presley's most famous films included Jailhouse Rock (1957), Blue Hawaii (1961), and Viva Las Vegas (1964). In 1968, he returned to the stage in the acclaimed NBC television comeback special Elvis, which led to an extended Las Vegas concert residency and several highly profitable tours. In 1973, Presley gave the first concert by a solo artist to be broadcast around the world, Aloha from Hawaii. Years of substance abuse and unhealthy eating severely compromised his health, and Presley died in August 1977 at his Graceland estate at the age of 42. Presley is one of the best-selling music artists in history, having sold an estimated 500 million records worldwide. He was commercially successful in many genres, including pop, country, rock and roll, rockabilly, rhythm and blues, adult contemporary, and gospel. Presley won three Grammy Awards, received the Grammy Lifetime Achievement Award at age 36, and has been posthumously inducted into multiple music halls of fame. He holds several records, including the most Recording Industry Association of America (RIAA)-certified gold and platinum albums, the most albums charted on the Billboard 200, the most number-one albums by a solo artist on the UK Albums Chart, and the most number-one singles by any act on the UK Singles Chart. In 2018, Presley was posthumously awarded the Presidential Medal of Freedom.
