Question: Which prominent mathematician in the Bernoulli family did Jakob II Bernoulli study under?

full_context: Document 1: Johann Bernoulli: Johann Bernoulli (also known as Jean or John; 6 August [O.S. 27 July] 1667 – 1 January 1748) was a Swiss mathematician and was one of the many prominent mathematicians in the Bernoulli family. He is known for his contributions to infinitesimal calculus and educating Leonhard Euler in the pupil's youth.
Document 2: Henry Benbridge: Henry Benbridge born October 1743 died February 1812, early American portrait painter, was born in Philadelphia, the only child of James and Mary (Clark) Benbridge. When he was seven years old, his mother, who had been left a widow, was married to Thomas Gordon, a wealthy Scot. The boy's artistic talent was encouraged. He made decorative designs for his stepfather's drawing-room which were much admired. When he was fourteen years old he may have watched John Wollaston paint Gordon's portrait. It has been plausibly argued that young Benbridge had instruction from Wollaston, since his earliest known portrait, that of his half-sister Rebecca Gordon, "seems to hark back to Wollaston." When he was 21, Benbridge was sent to Italy, where he studied with Pompeo Batoni and Anton Raphael Mengs. In 1769, on commission from James Boswell, biographer of Dr. Samuel Johnson, he made a portrait of Pasquale Paoli in Corsica which he took to London. It was exhibited (1769) at the Free Society of Artists, and from it three mezzotints were scraped and published with the artist's name signed "Bembridge." Like other young Americans he was encouraged by Benjamin West. He wrote, on December 7, 1769, to his stepfather: "Upon my arrival I waited upon Mr. West who received me with a sort of brotherly affection, as did my cousin, Mrs. West." Impelled, apparently, by a longing to rejoin his family, he left England in 1770, bearing from West the following note of recommendation to Francis Hopkinson: "By Mr. Benbridge you will receive these few lines. You will find him an Ingenous artist and an agreeable Companion. His merit in the art must procure him great incouragement and much esteem. I deare say it will give you great pleasure to have an ingenous artist resident amongst you."
Document 3: Jakob II Bernoulli: Jakob II Bernoulli (17 October 1759 in Basel – 3 July 1789 in Saint Petersburg), younger brother of Johann III Bernoulli. Having finished his literary studies, he was, according to custom, sent to Neuchâtel to learn French. On his return, he graduated in law. This study, however, did not check his hereditary taste for geometry. The early lessons which he had received from his father were continued by his uncle Daniel, and such was his progress that at the age of twenty-one he was called to undertake the duties of the chair of experimental physics, which his uncle’s advanced years rendered him unable to discharge. He afterwards accepted the situation of secretary to count de Brenner, which afforded him an opportunity of seeing Germany and Italy. In Italy, he formed a friendship with Lorgna, professor of mathematics at Verona, and one of the founders of the Società Italiana for the encouragement of the sciences. He was also made corresponding member of the royal society of Turin; and, while residing at Venice, he was, through the friendly representation of Nicolaus von Fuss, admitted into the academy of St Petersburg. In 1788, he was named one of its mathematical professors.
Document 4: Nicolaus II Bernoulli: Nicolaus II Bernoulli, a.k.a. Niklaus Bernoulli, Nikolaus Bernoulli, (6 February 1695, Basel, Switzerland – 31 July 1726, St. Petersburg, Russia) was a Swiss mathematician as were his father Johann Bernoulli and one of his brothers, Daniel Bernoulli. He was one of the many prominent mathematicians in the Bernoulli family.
Document 5: Nicolaus I Bernoulli: Nicolaus Bernoulli (born 21 October 1687 in Basel, died 29 November 1759 in Basel; also spelled Nicolas or Nikolas), was a Swiss mathematician and was one of the many prominent mathematicians in the Bernoulli family.
Document 6: Giovanni Maria Fontana: Giovanni Maria Fontana ("c"1670 – after 1712) was an Italian-Swiss architect, born in Lugano, who worked in Russia, on the invitation of Peter the Great, who assembled a team of European architects and artisans for the construction of St Petersburg during his grand tour in 1697 and 1698. Among his most prominent commissions were those from Aleksandr Danilovich Menshikov, to build his various palaces, including the Oranienbaum, often working in tandem with Johann Gottfried Schädel.
Document 7: Richard von Mises: Richard Edler von Mises ( ; ] ; 19 April 1883 – 14 July 1953) was a scientist and mathematician who worked on solid mechanics, fluid mechanics, aerodynamics, aeronautics, statistics and probability theory. He held the position of Gordon-McKay Professor of Aerodynamics and Applied Mathematics at Harvard University. He described his work in his own words shortly before his death as being on
Document 8: Peter Werenfels: Peter Werenfels (May 20, 1627 – May 23, 1703) was a Swiss theologian, professor at the University of Basel and antistes of the Basel church. He served as the doctoral advisor of prominent mathematician Jacob Bernoulli.
Document 9: Giovanni Battista Agucchi: Giovanni Battista Agucchi (20 November 1570, Bologna – 1 January 1632) was an Italian churchman, Papal diplomat and writer on art theory. He was the nephew and brother of cardinals, and might have been one himself if had lived longer. He served as secretary to the Papal Secretary of State, then the Pope himself, on whose death Agucchi was made a titular bishop and appointed as nuncio to Venice. He was an important figure in Roman art circles when he was in the city, promoting fellow-Bolognese artists, and was close to Domenichino in particular. As an art theorist he was rediscovered in the 20th century as having first expressed many of the views better known from the writings of Gian Pietro Bellori a generation later. He was also an amateur astronomer who corresponded with Galileo.
Document 10: Jean Claude Jacob: Jean Claude Jacob was a serf from the Jura Mountains, supposedly 120 years old, who was brought from his native place to figure as "dean of the human race" in Paris at the Festival of the Federation of July 1790. Thomas Carlyle wrote of Jacob in :Having seen the Human Species itself, to have seen the 'Dean of the Human Species,' ceased now to be a miracle. Such 'Doyen du Genre Humain, Eldest of Men,' had shewn himself there, in these weeks: Jean Claude Jacob, a born Serf, deputed from his native Jura Mountains to thank the National Assembly for enfranchising them. On his bleached worn face are ploughed the furrowings of one hundred and twenty years. He has heard dim patois-talk, of immortal Grand-Monarch victories; of a burnt Palatinate, as he toiled and moiled to make a little speck of this Earth greener; of Cevennes Dragoonings; of Marlborough going to the war. Four generations have bloomed out, and loved and hated, and rustled off: he was forty-six when Louis Fourteenth died. The Assembly, as one man, spontaneously rose, and did reverence to the Eldest of the World; old Jean is to take seance among them, honourably, with covered head. He gazes feebly there, with his old eyes, on that new wonder-scene; dreamlike to him, and uncertain, wavering amid fragments of old memories and dreams. For Time is all growing unsubstantial, dreamlike; Jean's eyes and mind are weary, and about to close, — and open on a far other wonder-scene, which shall be real. Patriot Subscription, Royal Pension was got for him, and he returned home glad; but in two months more he left it all, and went on his unknown way.
Document 11: Daniel Bernoulli: Daniel Bernoulli FRS ( ; ] ; 8 February 1700 – 17 March 1782) was a Swiss mathematician and physicist and was one of the many prominent mathematicians in the Bernoulli family. He is particularly remembered for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability and statistics. His name is commemorated in the Bernoulli's principle, a particular example of the conservation of energy, which describes the mathematics of the mechanism underlying the operation of two important technologies of the 20th century: the carburetor and the airplane wing.
Document 12: Johann III Bernoulli: Johann III Bernoulli (also known as Jean; 4 November 1744, Basel – 13 July 1807, Berlin), grandson of Johann Bernoulli, and son of Johann II Bernoulli. He was known around the world as a child prodigy. He studied at Basel and at Neuchâtel, and when thirteen years of age took the degree of doctor in philosophy. When he was fourteen, he got the degree of master of jurisprudence. At nineteen he was appointed astronomer royal of Berlin. A year later, he reorganized the astronomical observatory at the Berlin Academy. Some years after, he visited Germany, France and England, and subsequently Italy, Russia and Poland. His travel accounts were of great cultural and historical importance (1772–1776; 1777–1779; 1781). He wrote about Kashubians.
Document 13: Jacob Bernoulli: Jacob Bernoulli (also known as James or Jacques; 6 January 1655 [O.S. 27 December 1654] – 16 August 1705) was one of the many prominent mathematicians in the Bernoulli family. He was an early proponent of Leibnizian calculus and had sided with Leibniz during the Leibniz–Newton calculus controversy. He is known for his numerous contributions to calculus, and along with his brother Johann, was one of the founders of the calculus of variations. He also discovered the fundamental mathematical constant e. However, his most important contribution was in the field of probability, where he derived the first version of the law of large numbers in his work "Ars Conjectandi".
Document 14: Ole Jacob Broch: Ole Jacob Broch (14 January 1818 – 5 February 1889) was a Norwegian mathematician, physicist, economist and politician. Broch was born in Fredrikstad, the son of war commissary Johan Jørgen Broch (1791–1860) and Jensine Laurentze Bentzen (1790–1877), and the brother of the orientalist Jens Peter Broch. He showed a talent for mathematics at an early age, and after studies in Christiania (today's Oslo), he travelled abroad. Through studies in Paris, Berlin and Königsberg, he developed an interest also for optics and statistics.
Document 15: Johann II Bernoulli: Johann II Bernoulli (18 May 1710, Basel – 17 July 1790, Basel; also known as Jean) was the youngest of the three sons of Johann Bernoulli. He studied law and mathematics, and, after travelling in France, was for five years professor of eloquence in the university of his native city. In 1736 he was awarded the prize of the French Academy for his suggestive studies of aether. On the death of his father he succeeded him as professor of mathematics in the University of Basel. He was thrice a successful competitor for the prizes of the Academy of Sciences of Paris. His prize subjects were the capstan, the propagation of light, and the magnet. He enjoyed the friendship of P. L. M. de Maupertuis, who died under his roof while on his way to Berlin. He himself died in 1790. His two sons, Johann and Jakob, are the last noted mathematicians of the Bernoulli family.
