PROBLEM: Passage: As far as we know, the earliest cantatas of Johann Sebastian Bach were performed in Mühlhausen from 1706 to 1708. He was employed as an organist there, but he occasionally composed cantatas, mostly for special occasions. The cantatas were based mainly on biblical texts and hymns, such as Aus der Tiefen rufe ich, Herr, zu dir, BWV 131 (a psalm setting), and the Easter chorale cantata Christ lag in Todes Banden, BWV 4.
Bach was next appointed organist and chamber musician in Weimar on 25 June 1708 at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August. He initially concentrated on the organ, composing major works for the instrument, including the Orgelbüchlein, the Toccata and Fugue in D minor, BWV 565, and the Prelude and Fugue in E major, BWV 566. He was promoted to Konzertmeister on 2 March 1714, an honour that entailed performing a church cantata monthly in the Schlosskirche. The first cantatas he composed in the new position were Himmelskönig, sei willkommen, BWV 182, for Palm Sunday, Weinen, Klagen, Sorgen, Zagen, BWV 12 for Jubilate Sunday, and Erschallet, ihr Lieder, BWV 172, for Pentecost. Mostly inspired by texts by the court poet, Salomo Franck, they contain recitatives and arias. When Johann Samuel Drese, the Kapellmeister (director of music), died in 1716, Bach hoped in vain to become his successor. Bach looked for a better position and found it as Kapellmeister at the court of Leopold, Prince of Anhalt-Köthen. However, the duke in Weimar did not dismiss him and arrested him for disobedience. He was released on 2 December 1717.In Köthen, Bach found an employer who was an enthusiastic musician himself. The court was Calvinist, therefore Bach's work from this period was mostly secular, including the orchestral suites, the cello suites, the sonatas and partitas for solo violin, and the Brandenburg Concertos. He composed secular cantatas for the court for occasions such as New Year's Day and the prince's birthday, including Die Zeit, die Tag und Jahre macht, BWV 134a. He later parodied some of them as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend weiß, BWV 134. 
Question: What is the last name of the person who parodied some secular cantatas as church cantatas without major changes, for example Ein Herz, das seinen Jesum lebend weiß, BWV 134?

SOLUTION: Bach.

PROBLEM: Passage: The attribution of the panel reflects the progression and trends of 19th and 20th-century scholarship on Early Netherlandish art. It is now thought to have been completed c. 1438–40, but there are still arguments for dates as early as 1424–29. As with the pages ascribed to Hand G in the Turin-Milan Hours manuscript, the panel was attributed to Jan's brother Hubert van Eyck in the 1875 Gemäldegalerie catalogue, and by a 1911 claim by art historian Georges Hulin de Loo. This is no longer considered credible and Hubert, today, is credited with very few works. By 1912 the painting had been definitively attributed to Jan in the museum catalogue.Attempts to date it have undergone similar shifts of opinion. In the 19th century the panel was believed to be an early work by Jan completed as early as c. 1410, although this view changed as scholarship progressed. In the early 20th century, Ludwig von Baldass placed it around 1424–29, then for a long period it was seen as originating from the early 1430s. Erwin Panofsky provided the first detailed treatise on the work and placed it around 1432–34. However, following research from Meyer Schapiro, he revised his opinion to the late 1430s in the 1953 edition of his Early Netherlandish Painting. A 1970s comparative study of van Eyck's 1437 Saint Barbara concluded that Madonna in the Church was completed after c. 1437. In the 1990s, Otto Pächt judged the work as probably a late van Eyck, given the similar treatment of an interior in the 1434 Arnolfini Portrait. In the early 21st century, Jeffrey Chipps Smith and John Oliver Hand placed it between 1426 and 1428, claiming it as perhaps the earliest extant signed work confirmed as by Jan. 
Question: What is the full name of the person who is credited with very few works?

SOLUTION: Hubert van Eyck.
