Question: Who was the father of the Oboe Concerto composer?

full_context: Document 1: Franz Xaver Wolfgang Mozart: Franz Xaver Wolfgang Mozart (26 July 1791 – 29 July 1844), also known as Wolfgang Amadeus Mozart, Jr., was the youngest child of six born to Wolfgang Amadeus Mozart and his wife Constanze. He was the younger of his parents' two surviving children. He was a composer, pianist, conductor, and teacher from the late classical period whose musical style was of an early Romanticism, heavily influenced by his father's mature style.
Document 2: Wolfgang Amadeus Mozart: Wolfgang Amadeus Mozart (/ ˈwʊlfɡæŋ æməˈdeɪəs ˈmoʊtsɑːrt / MOHT - sart; German: (ˈvɔlfɡaŋ amaˈdeːʊs ˈmoːtsaʁt); 27 January 1756 -- 5 December 1791), baptised as Johannes Chrysostomus Wolfgangus Theophilus Mozart, was a prolific and influential composer of the Classical era.
Document 3: Biographies of Mozart: Wolfgang Amadeus Mozart died after a short illness on 5 December 1791, aged 35. His reputation as a composer, already strong during his lifetime, rose rapidly in the years after his death, and he became (as he has remained to this day) one of the most celebrated of all composers.
Document 4: Violin Concerto No. 1 (Mozart): Wolfgang Amadeus Mozart's Violin Concerto No. 1 in B-flat major, K. 207, once was supposed to have been composed in 1775 (when Mozart was 19), along with the other four wholly authentic violin concertos. However, analysis of handwriting and the manuscript paper on which the concerto was written suggest that the date of composition might have been 1773. It has the usual fast-slow-fast structure.
Document 5: Horn Concerto No. 1 (Mozart): This is one of two horn concertos of Mozart to include bassoons (the other is K. 447), but in this one he "treats them indifferently in the first movement." It is the only one of Mozart's horn concertos to be in D major (the rest are in E-flat major) and the only one to have just two movements instead of the usual three (with the exception of the incompletely scored horn concerto, K. 370b+371).
Document 6: Horn Concertos (Mozart): The Horn Concertos by Wolfgang Amadeus Mozart were written for his friend Joseph Leutgeb whom he had known since childhood. Leutgeb was a skilled player, as the works are very difficult to perform on the natural horn of the period, requiring lip trills, much hand-stopping, and rapid tonguing.
Document 7: Amadeus (film): Mozart: The Magic Flute, K. 620, Overture Mozart: The Magic Flute, K. 620, Act II, The Queen of the Night aria (``Der Hölle Rache kocht in meinem Herzen '') Mozart: Masonic Funeral Music, K. 477 Mozart: Piano Concerto No. 20 in D minor, K. 466, 1st movement Antonio Salieri: Axur, re d'Ormus, Finale Mozart: Eine kleine Nachtmusik (Serenade No. 13 for Strings in G major), K. 525, 1st movement, arranged for woodwind octet by Graham Sheen Mozart: Concerto for Flute and Harp in C major, K. 299, 2nd movement Mozart: Six German Dances (Nos. 1 -- 3), K. 509 Giuseppe Giordani:`` Caro mio ben'' Mozart: The Abduction from the Seraglio, K. 384, Chorus of the Janissaries (Arr.) and ``Ich möchte wohl der Kaiser sein ''(`` Ein deutsches Kriegslied''), K. 539 (Arr.)
Document 8: Sinfonia Concertante for Four Winds: The Sinfonia Concertante for Four Winds in E flat major is a work thought to be by Wolfgang Amadeus Mozart, for oboe, clarinet, horn, bassoon, and orchestra, K. 297b (Anh. C 14.01). He originally wrote a work for flute, oboe, horn, bassoon, and orchestra, K. Anh. 9 (297B), in Paris in April 1778. There is considerable debate about the relation of the work as it is performed today to this original work.
Document 9: Symphony, K. 45b (Mozart): This work was only known to Ludwig Ritter von Köchel as an incipit in the catalogue of Breitkopf & Härtel, and thus it was placed in the Anhang as K. Anh. 214. Alfred Einstein then discovered a set of parts in the Berlin State Library with the title ""Synfonia Ex Bb...Del Sigr. cavaliere Amadeo Wolfgango Mozart Maestro di concerto di S.A. á Salisburgo"". Wolfgang became the Concertmaster to the Archbishop of Salzburg in November 1769, and was given the title "cavaliere" in July 1770, but as this is a later copy, this information cannot be used for dating purposes. Einstein believed the symphony to date from early 1768 on stylistic grounds; Neal Zaslaw and Gerhard Allroggen believe even earlier dates to also be possible, and Zaslaw dated the symphony cautiously to Salzburg in 1767. Einstein also believed that the symphonies in the catalogue of Breitkopf & Härtel were sent by Leopold Mozart to be published.
Document 10: Luigi Gatti: Luigi Gatti (October 7, 1740 – March 1, 1817) was a classical composer. He was born in Lazise in 1740, the son of an organist, Francesco della Gatta. He was ordained a priest in Mantua. In the 1780s he became Hofkapellmeister in Salzburg and Leopold Mozart showed his irritation at not receiving it himself. Between 1801 and 1804 Gatti helped Mozart's sister, Nannerl to locate unknown pieces by Mozart. He died in Salzburg in 1817.
Document 11: Horn Concerto No. 3 (Mozart): Wolfgang Amadeus Mozart's Horn Concerto No. 3 in E-flat major, K. 447, was completed between 1784 and 1787, during the Vienna Period.
Document 12: Piece in F for Keyboard, K. 33B (Mozart): Mozart wrote this piece in pencil on the back of a circular by the Zürcher Musikkollegium (Zürich Music College) dated 30 September 1766, when the Mozart family came to the end of their Grand Tour. The circular invited sponsors, music lovers and other people who might be interested to concerts by "the young (9 years old) Master Mozart as well as his maiden sister" (Maria Anna – Nannerl) on October 7 and 9. It can be assumed that Mozart played or improvised this lively piece in one of those concerts, the programs to which are lost. Mozart wrote it on the back of the circular probably as a souvenir for the College's board; otherwise he would have used his sister's notebook or his third book of sketches (""), which is also lost. The autograph became known very late (in 1942), and so is missing from Alfred Einstein's 3rd edition of the Köchel catalogue.
Document 13: Wolfgang Amadeus Mozart: Wolfgang Amadeus Mozart was born on 27January 1756 to Leopold Mozart (1719–1787) and Anna Maria, née Pertl (1720–1778), at 9 Getreidegasse in Salzburg. This was the capital of the Archbishopric of Salzburg, an ecclesiastic principality in what is now Austria, then part of the Holy Roman Empire. He was the youngest of seven children, five of whom died in infancy. His elder sister was Maria Anna Mozart (1751–1829), nicknamed "Nannerl". Mozart was baptised the day after his birth, at St. Rupert's Cathedral in Salzburg. The baptismal record gives his name in Latinized form, as "Joannes Chrysostomus Wolfgangus Theophilus Mozart". He generally called himself "Wolfgang Amadè Mozart" as an adult, but his name had many variants.
Document 14: Mozart's birthplace: Mozart's birthplace (German: ' or ') was the birthplace of Wolfgang Amadeus Mozart at No. 9 Getreidegasse in Salzburg, Austria. The Mozart family resided on the third floor from 1747 to 1773. Mozart himself was born here on 27 January 1756. He was the seventh child of Leopold Mozart, who was a musician of the Salzburg Royal Chamber.
Document 15: Oboe Concerto (Mozart): Wolfgang Amadeus Mozart's Oboe Concerto in C major, K. 314 (271k), was composed in the spring or summer of 1777, for the oboist Giuseppe Ferlendis (1755–1802) from Bergamo. In 1778, Mozart re-worked it as a concerto for flute in D major. The concerto is a widely studied piece for both instruments and is one of the more important concertos in the oboe repertoire.
