Problem: Background: Robert Schumann (; 8 June 1810 - 29 July 1856) was a German composer and an influential music critic. He is widely regarded as one of the greatest composers of the Romantic era. Schumann left the study of law, intending to pursue a career as a virtuoso pianist. He had been assured by his teacher Friedrich Wieck, a German pianist, that he could become the finest pianist in Europe, but a hand injury ended this dream.
Context: Schumann was born in Zwickau, in the Kingdom of Saxony, the fifth and last child of Johanna Christiane (nee Schnabel) and August Schumann. Schumann began to compose before the age of seven, but his boyhood was spent in the cultivation of literature as much as music - undoubtedly influenced by his father, a bookseller, publisher, and novelist.  Schumann began receiving general musical and piano instruction at the age of seven from Johann Gottfried Kuntzsch, a teacher at the Zwickau high school. The boy immediately developed a love of music and worked at creating musical compositions himself, without the aid of Kuntzsch. Even though he often disregarded the principles of musical composition, he created works regarded as admirable for his age. The Universal Journal of Music 1850 supplement included a biographical sketch of Schumann that noted, "It has been related that Schumann, as a child, possessed rare taste and talent for portraying feelings and characteristic traits in melody, - ay, he could sketch the different dispositions of his intimate friends by certain figures and passages on the piano so exactly and comically that everyone burst into loud laughter at the similitude of the portrait."  At age 14, Schumann wrote an essay on the aesthetics of music and also contributed to a volume, edited by his father, titled Portraits of Famous Men. While still at school in Zwickau, he read the works of the German poet-philosophers Schiller and Goethe, as well as Byron and the Greek tragedians. His most powerful and permanent literary inspiration was Jean Paul, a German writer whose influence is seen in Schumann's youthful novels Juniusabende, completed in 1826, and Selene.  Schumann's interest in music was sparked by seeing a performance of Ignaz Moscheles playing at Karlsbad, and he later developed an interest in the works of Beethoven, Schubert and Mendelssohn. His father, who had encouraged the boy's musical aspirations, died in 1826 when Schumann was 16. Neither his mother nor his guardian thereafter encouraged a career in music. In 1828 Schumann left school, and after a tour during which he met Heinrich Heine in Munich, he went to Leipzig to study law (to meet the terms of his inheritance). In 1829 his law studies continued in Heidelberg, where he became a lifelong member of Corps Saxo-Borussia Heidelberg.

Problem: Background: Bad Brains is an American hardcore punk band formed in Washington, D.C., in 1977. They are widely regarded as among the pioneers of hardcore punk, though the band's members have objected to this term to describe their music. They are also an adept reggae band, while later recordings featured elements of other genres like funk, heavy metal, hip hop and soul. Bad Brains are followers of the Rastafari movement.
Context: The band was first founded in 1976 as a jazz fusion ensemble called Mind Power in the mold of bands such as Chick Corea's Return to Forever and John McLaughlin's Mahavishnu Orchestra as well as R&B musician Stevie Wonder. In 1977, their friend Sid McCray introduced the band, who were already interested in bands such as Black Sabbath, to punk rock, including the Dickies, the Dead Boys, and the Sex Pistols. Mind Power became obsessed with punk rock and changed their name to "Bad Brains", after the Ramones song "Bad Brain", but with the word "bad" in the sense of "good". Despite their burgeoning punk sound, the early Bad Brains, after seeing Bob Marley in concert, also delved deep into reggae music and the Rastafari movement. Sid McCray became their first singer but left in the early days of the group's hardcore punk era, and guitarist H.R. became the band's new singer.  The band developed an early reputation in Washington D.C., due in part to the relative novelty of an entirely black band playing punk rock at the time, but also due to their high-energy performances and undeniable talent.  In 1979, Bad Brains found themselves the subject of an unofficial ban among Washington D.C. area clubs and performance venues (later addressed in their song, "Banned in D.C."). The band subsequently relocated to New York City, where they would serve as a catalyst for that city's burgeoning hardcore scene. At first, the Brains stayed with their NYC friends in the bands The Mad and The Stimulators.  Their self-titled debut album was released on Neil Cooper's ROIR on "cassette only" on February 5, 1982, followed in 1983 by Rock for Light, produced by Ric Ocasek of The Cars.
Question: Who were the original personnel?
Answer: Mahavishnu Orchestra as well as R&B musician Stevie Wonder.

Problem: Background: Lee de Forest was born in 1873 in Council Bluffs, Iowa, the son of Anna Margaret (nee Robbins) and Henry Swift DeForest. He was a direct descendant of Jesse de Forest, the leader of a group of Walloon Huguenots who fled Europe in the 17th Century due to religious persecution. De Forest's father was a Congregational Church minister who hoped his son would also become a pastor. In 1879 the elder de Forest became president of the American Missionary Association's Talladega College in Talladega, Alabama, a school "open to all of either sex, without regard to sect, race, or color", and which educated primarily African-Americans.
Context: At the 1904 Louisiana Purchase Exposition, Valdemar Poulsen had presented a paper on an arc transmitter, which unlike the discontinuous pulses produced by spark transmitters, created steady "continuous wave" signals that could be used for amplitude modulated (AM) audio transmissions. Although Poulsen had patented his invention, de Forest claimed to have come up with a variation that allowed him to avoid infringing on Poulsen's work. Using his "sparkless" arc transmitter, de Forest first transmitted audio across a lab room on December 31, 1906, and by February was making experimental transmissions, including music produced by Thaddeus Cahill's telharmonium, that were heard throughout the city.  On July 18, 1907, de Forest made the first ship-to-shore transmissions by radiotelephone -- race reports for the Annual Inter-Lakes Yachting Association (I-LYA) Regatta held on Lake Erie -- which were sent from the steam yacht Thelma to his assistant, Frank E. Butler, located in the Fox's Dock Pavilion on South Bass Island. De Forest also interested the U.S. Navy in his radiotelephone, which placed a rush order to have 26 arc sets installed for its Great White Fleet around-the-world voyage that began in late 1907. However, at the conclusion of the circumnavigation the sets were declared to be too unreliable to meet the Navy's needs and removed.  The company set up a network of radiotelephone stations along the Atlantic coast and the Great Lakes, for coastal ship navigation. However, the installations proved unprofitable, and by 1911 the parent company and its subsidiaries were on the brink of bankruptcy.
