Background: Rudolf Joseph Lorenz Steiner (27 (or 25) February 1861 - 30 March 1925) was an Austrian philosopher, social reformer, architect and esotericist. Steiner gained initial recognition at the end of the nineteenth century as a literary critic and published philosophical works including The Philosophy of Freedom. At the beginning of the twentieth century he founded an esoteric spiritual movement, anthroposophy, with roots in German idealist philosophy and theosophy; other influences include Goethean science and Rosicrucianism. In the first, more philosophically oriented phase of this movement, Steiner attempted to find a synthesis between science and spirituality.
Context: Steiner's father, Johann(es) Steiner (1829 - 1910), left a position as a gamekeeper in the service of Count Hoyos in Geras, northeast Lower Austria to marry one of the Hoyos family's housemaids, Franziska Blie (1834 Horn - 1918, Horn), a marriage for which the Count had refused his permission. Johann became a telegraph operator on the Southern Austrian Railway, and at the time of Rudolf's birth was stationed in Kraljevec in the Murakoz region of the Austrian Empire (present-day Donji Kraljevec in the Medimurje region of northernmost Croatia). In the first two years of Rudolf's life, the family moved twice, first to Modling, near Vienna, and then, through the promotion of his father to stationmaster, to Pottschach, located in the foothills of the eastern Austrian Alps in Lower Austria. Steiner entered the village school; following a disagreement between his father and the schoolmaster, he was briefly educated at home. In 1869, when Steiner was eight years old, the family moved to the village of Neudorfl and in October 1872 Steiner proceeded from the village school there to the realschule in Wiener Neustadt. In 1879, the family moved to Inzersdorf to enable Steiner to attend the Vienna Institute of Technology, where he studied mathematics, physics, chemistry, botany, biology, literature, and philosophy on an academic scholarship from 1879 to 1883, at the end of which time he withdrew from the institute without graduating. In 1882, one of Steiner's teachers, Karl Julius Schroer, suggested Steiner's name to Joseph Kurschner, chief editor of a new edition of Goethe's works, who asked Steiner to become the edition's natural science editor, a truly astonishing opportunity for a young student without any form of academic credentials or previous publications. Before attending the Vienna Institute of Technology, Steiner had studied Kant, Fichte and Schelling.
Question: What did he study there ?
Answer: he studied mathematics, physics, chemistry, botany, biology, literature, and philosophy on an academic scholarship

Background: Stephen Ray Vaughan (October 3, 1954 - August 27, 1990) was an American musician, singer, songwriter, and record producer. In spite of a short-lived mainstream career spanning seven years, he was one of the most influential guitarists in the revival of blues in the 1980s. AllMusic describes him as "a rocking powerhouse of a guitarist who gave blues a burst of momentum in the '80s, with influence still felt long after his tragic death." Born and raised in Dallas, Texas, Vaughan began playing guitar at the age of seven, inspired by his older brother Jimmie.
Context: In May 1969, after leaving the Brooklyn Underground, Vaughan joined a band called the Southern Distributor. He had learned The Yardbirds' "Jeff's Boogie" and played the song at the audition. Mike Steinbach, the group's drummer, commented: "The kid was fourteen. We auditioned him on 'Jeff's Boogie,' really fast instrumental guitar, and he played it note for note." Although they played pop rock covers, Vaughan conveyed his interest in the addition of blues songs to the group's repertoire; he was told that he wouldn't earn a living playing blues music and the band parted ways. Later that year, bassist Tommy Shannon walked into a Dallas club and heard Vaughan playing guitar. Fascinated by the skillful playing, which he described as "incredible even then", Shannon borrowed a bass guitar and the two jammed. Within a few years, they began performing together in a band called Krackerjack. In February 1970, Vaughan joined a band called Liberation, which was a nine-piece group with a horn section. Having spent the past month briefly playing bass with Jimmie in Texas Storm, he had originally auditioned as bassist. Impressed by Vaughan's guitar playing, Scott Phares, the group's original guitarist, modestly became the bassist. In mid-1970, they performed at the Adolphus Hotel in downtown Dallas, where ZZ Top asked them to perform. During Liberation's break, Vaughan jammed with ZZ Top on the Nightcaps song "Thunderbird". Phares later described the performance: "They tore the house down. It was awesome. It was one of those magical evenings. Stevie fit in like a glove on a hand." Attending Justin F. Kimball High School during the early 1970s, Vaughan's late-night gigs contributed to his neglect in his studies, including music theory; he would often sleep during class. His musical career pursuit was disapproved by many of the school's administrators, but he was also encouraged by many people to strive for a career in art, including his art teacher. In his sophomore year, he attended an evening class for experimental art at Southern Methodist University, but bailed when it conflicted with rehearsal. Vaughan later spoke of his dislike of the school and stated that he had to receive a daily note from the principal about his grooming.
