Problem: Background: Robert Walser (15 April 1878 - 25 December 1956) was a German-speaking Swiss writer. Walser is understood to be the missing link between Kleist and Kafka. "Indeed," writes Susan Sontag, "At the time [of Walser's writing], it was more likely to be Kafka [who was understood by posterity] through the prism of Walser. Robert Musil, another admirer among Walser's contemporaries, when he first read Kafka pronounced [Kafka's work] as, 'a peculiar case of the Walser type.'
Context: In 1898, the influential critic Joseph Victor Widmann published a series of poems by Walser in the Bernese newspaper Der Bund. This came to the attention of Franz Blei, and he introduced Walser to the Art Nouveau people around the magazine Die Insel, including Frank Wedekind, Max Dauthendey and Otto Julius Bierbaum. Numerous short stories and poems by Walser appeared in Die Insel.  Until 1905, Walser lived mainly in Zurich, though he often changed lodgings and also lived for a time in Thun, Solothurn, Winterthur and Munich. In 1903, he fulfilled his military service obligation and, beginning that summer, was the "aide" of an engineer and inventor in Wadenswil near Zurich. This episode became the basis of his 1908 novel Der Gehulfe (The Assistant). In 1904, his first book, Fritz Kochers Aufsatze, appeared in the Insel Verlag.  At the end of 1905 he attended a course in order to become a servant at the castle of Dambrau in Upper Silesia. The theme of serving would characterize his work in the following years, especially in the novel Jakob von Gunten (1909). In 1905, he went to live in Berlin, where his brother Karl Walser, who was working as a theater painter, introduced him to other figures in literature, publishing, and the theater. Occasionally, Walser worked as secretary for the artists' corporation Berliner Secession.  In Berlin, Walser wrote the novels Geschwister Tanner, Der Gehulfe and Jakob von Gunten. They were issued by the publishing house of Bruno Cassirer, where Christian Morgenstern worked as editor. Apart from the novels, he wrote many short stories, sketching popular bars from the point of view of a poor "flaneur" in a very playful and subjective language. There was a very positive echo to his writings. Robert Musil and Kurt Tucholsky, among others, stated their admiration for Walser's prose, and authors like Hermann Hesse and Franz Kafka counted him among their favorite writers.  Walser published numerous short stories in newspapers and magazines, many for instance in the Schaubuhne. They became his trademark. The larger part of his work is composed of short stories - literary sketches that elude a ready categorization. Selections of these short stories were published in the volumes Aufsatze (1913) and Geschichten (1914).
Question: Was that his first published work?
Answer: In 1904, his first book, Fritz Kochers Aufsatze,

Background: Stanley Kirk Burrell (born March 30, 1962), better known by his stage name MC Hammer (or simply Hammer), is an American hip hop recording artist, dancer, record producer and entrepreneur. He had his greatest commercial success and popularity from the late 1980s, until the early 1990s. Remembered for his rapid rise to fame, Hammer is known for hit records (such as "U Can't Touch This" and "2 Legit 2 Quit"), flashy dance movements, choreography and eponymous Hammer pants. A multi-award winner, M.C. Hammer is considered a "forefather/pioneer" and innovator of pop rap (incorporating elements of freestyle music), and is the first hip hop artist to achieve diamond status for an album.
Context: Before Hammer's successful music career (with his mainstream popularity lasting approximately between 1988 and 1998) and his "rags-to-riches-to-rags-and-back saga", Burrell formed a Christian rap music group with CCM's Jon Gibson (or "J.G.") called Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as K.B. and then eventually M.C. Hammer once it was produced), was later released on Gibson's album Change of Heart (1988). This was Contemporary Christian music's first rap hit ever. Burrell also produced "Son of the King" at that time, releasing it on his debut album. "Son of the King" showed up on Hammer's debut album Feel My Power (1987), as well as the re-released version Let's Get It Started (1988).  With exception to later remixes of early releases, Hammer produced and recorded many rap songs that were never made public, yet are now available on the Internet. Via his record labels such as Bust It Records, Oaktown Records and FullBlast, Hammer has introduced, signed and produced new talent including Oaktown's 3.5.7, Ho Frat Hoo!, the vocal quintet Special Generation, Analise, James Greer, One Cause One Effect, B Angie B, The Stooge Playaz, DASIT (as seen on ego trip's The (White) Rapper Show), Teabag, Common Unity, Geeman and Pleasure Ellis; both collaborating with him and producing music of their own during his career.  At about the age of 12, Oakland native Keyshia Cole recorded with Hammer and sought career advice from him.
Question: What did he do in entertainment other than music?
Answer:
At about the age of 12, Oakland native Keyshia Cole recorded with Hammer and sought career advice from him.
