Sir Lawrence Alma-Tadema,  (; born Lourens Alma Tadema Dutch pronunciation: ['l^ur@ns 'alma: 'ta:d@,ma:]; 8 January 1836 - 25 June 1912) was a Dutch painter of special British denizenship.
In 1852 he entered the Royal Academy of Antwerp in Belgium where he studied early Dutch and Flemish art, under Gustaf Wappers. During Alma-Tadema's four years as a registered student at the Academy, he won several respectable awards.  Before leaving school, towards the end of 1855, he became assistant to the painter and professor Louis (Lodewijk) Jan de Taeye, whose courses in history and historical costume he had greatly enjoyed at the Academy. Although de Taeye was not an outstanding painter, Alma-Tadema respected him and became his studio assistant, working with him for three years. De Taeye introduced him to books that influenced his desire to portray Merovingian subjects early in his career. He was encouraged to depict historical accuracy in his paintings, a trait for which the artist became known.  Alma-Tadema left Taeye's studio in November 1858 returning to Leeuwarden before settling in Antwerp, where he began working with the painter Baron Jan August Hendrik Leys, whose studio was one of the most highly regarded in Belgium. Under his guidance Alma-Tadema painted his first major work: The Education of the children of Clovis (1861). This painting created a sensation among critics and artists when it was exhibited that year at the Artistic Congress in Antwerp. It is said to have laid the foundation of his fame and reputation. Alma-Tadema related that although Leys thought the completed painting better than he had expected, he was critical of the treatment of marble, which he compared to cheese.  Alma-Tadema took this criticism very seriously, and it led him to improve his technique and to become the world's foremost painter of marble and variegated granite. Despite any reproaches from his master, The Education of the Children of Clovis was honorably received by critics and artists alike and was eventually purchased and subsequently given to King Leopold of Belgium.

Answer the question at the end by quoting:

Sun Ra (born Herman Poole Blount, legal name Le Sony'r Ra; May 22, 1914 - May 30, 1993) was an American jazz composer, bandleader, piano and synthesizer player, and poet known for his experimental music, "cosmic" philosophy, prolific output, and theatrical performances. For much of his career, Ra led "The Arkestra", an ensemble with an ever-changing name and flexible line-up. Born and raised in Alabama, Blount eventually became involved in the Chicago jazz scene during the 1940s. He soon abandoned his birth name, taking the name Sun Ra (after Ra, the Egyptian God of the Sun) and developing a complex persona and mythology that would make him a pioneer of Afrofuturism: he claimed he was an alien from Saturn on a mission to preach peace, and throughout his life he consistently denied any ties to his prior identity.
After the move to New York, Sun Ra and company plunged headlong into the experimentalism that they had only hinted at in Chicago. The music was often extremely loud and the Arkestra grew to include multiple drummers and percussionists. In recordings of this era, Ra began to use new technologies--such as extensive use of tape delay--to assemble spatial sound pieces that were far removed from earlier compositions such as Saturn. Recordings and live performances often featured passages for unusual instrumental combinations, and passages of collective playing that incorporated free improvisation. It is often difficult to tell where compositions end and improvisations begin.  In this era, Sun Ra began conducting using hand and body gestures. This system inspired cornetist Butch Morris, who later developed his own more highly refined way to conduct improvisers.  Though often associated with avant-garde jazz, Sun Ra did not believe his work could be classified as "free music": "I have to make sure that every note, every nuance, is correct... If you want to call it that, spell it p-h-r-e, because ph is a definite article and re is the name of the sun. So I play phre music - music of the sun."  Seeking to broaden his compositional possibilities, Sun Ra insisted all band members double on various percussion instruments - predating world music by drawing on various ethnic musical forms - and most saxophonists became multireedists, adding instruments such as flutes, oboes, or clarinets to their arsenals. In this era, Sun Ra was among the first of any musicians to make extensive and pioneering use of synthesizers and other various electronic keyboards; he was given a prototype Minimoog by its inventor, Robert Moog. According to the Bob Moog Foundation: "Sun Ra first met Robert Moog after Downbeat journalist and Sun Ra acquaintance Tam Fiofori arranged for a visit to Moog's factory in Trumansburg in the Fall of 1969....it was during this visit that Moog loaned Sun Ra a prototype Minimoog (Model B), several months before the commercial instrument (Model D) was introduced in March 1970. Ra immediately added the instrument to his repertoire of keyboards, later acquired a second, and featured the Minimoog prominently on many of his recordings of the early 1970s."  Notable titles from this period include The Magic City, Cosmic Tones for Mental Therapy, When Sun Comes Out, The Heliocentric Worlds of Sun Ra, Volume One, Atlantis, Secrets of the Sun and Other Planes of There.
