John Campbell was born in or before 1720, parish of Kirkbean, near Dumfries, Kirkcudbrightshire, Scotland and died 16 December 1790, at his house at Charles Street, Berkeley Square, London, England. Campbell was a British naval officer, navigational expert and colonial governor.
Campbell joined the Royal Navy at an early age and sailed around the world in 1740 on the Centurion. He later became known as a navigational expert, and was from 1782 to his death Governor and Commander-in-Chief in Newfoundland.

John Campbell was born at Kirkbean close to the birth place of John Paul Jones, 'Father of the American Navy'.
His father, John Campbell (d. 1733), was minister of Kirkbean and John was at an early age apprenticed to the master of a coasting vessel. That vessel's mate was pressed into the navy, and John is said to have entered the navy by offering himself in exchange for him. He served for three years in the Blenheim, Torbay, and Russell before being appointed in 1740 as a midshipman to the Centurion. On the Centurion's ensuing circumnavigation of the world as the flagship of Commodore George Anson, he was promoted master's mate when a vacancy came up soon after sailing, and was promoted to master after the 1743 engagement against the Manila galleon Nuestra Señora de Covadonga. One of his fellow midshipmen was Augustus Keppel, who from then on became a lifelong friend.
Returning home in January 1745, Campbell passed the examination for lieutenant and, with Anson's influence behind him, rapidly gained a first command (a sloop) and - in November 1747 - a second, with promotion to post captain of the new frigate Bellona, a command he held until the peace in 1748. Praised for his successes on the Bellona, in 1749 he was given command of the expedition to the Pacific by the sloop Porcupine and the Raven, then of one to the north-west and north-east passages in the Atlantic, both of which were proposed but then called off for political reasons.
Meanwhile, in about 1747, Campbell had his first direct involvement in the development of astronomical navigation, as the first person to use a Hadley quadrant to measure the angular distance between the moon and fixed stars.[1] The astronomer royal, James Bradley, was shown Campbell's results and found them to correspond exactly with the actual distances in the sky, and Bradley and Campbell together made frequent observations at Greenwich of the moon's distance from the sun and stars, and of the stars' distances from one another.
His next commands after the Bellona were the Mermaid, the Prince (90 guns) and - in 1757 - the Essex (64 guns) under Edward Hawke in the Bay of Biscay and the blockade of Brest (barring an interlude in 1758/59, as flag captain to Anson in the Royal George when he temporarily took over command of the Brest fleet). During Campbell's command of the Essex, in 1756, James Bradley suggested to the Board of Longitude (chaired by Anson) that Campbell should give a sea trial to Tobias Mayer's new lunar tables and reflecting circle, and Campbell did so successfully within sight of the French coast, ‘though they [the observations] were not taken with all the advantages that might have attended them, had I been alone; for I was all the cruise in company with an admiral whose motions I was obliged to follow’,[2] in trials which would profoundly influence marine navigation for the next 250 years. He compared Mayer's new reflecting circle instrument with the common wooden Hadley octant as means of observing lunar distances, and in doing so found Mayer's was much too heavy whereas Hadley's - though it could not measure angles beyond 90° and was often unstable in its wooden frame - was far more useful. From this, he suggested modifications to the Hadley octant, extending its arc from 45° to 60° (to allow the measurement of arcs up to 120°) and making it of brass not wood. In 1759 John Bird, commissioned by the Board of Longitude, produced an instrument taking up both suggestions, a sextant of 20 inches radius with a brass frame[3] and 1/3 the weight of the 16-inch-diameter (410 mm) reflecting circle,[3] which served as a prototype of the marine sextant still used today.
Campbell, meanwhile, returned to the Royal George as flag captain in November 1759, this time under Hawke (when Hawke moved his flag to that ship), serving as such during the decisive battle of Quiberon Bay on 20 November 1759. It was Campbell whom Hawke sent to England on 24 November in the frigate Vengeance with news of the victory, and after a six-day voyage Campbell, accompanied by Lord Anson (now First Lord of the Admiralty), personally gave the king the news.
Next, Campbell was captain of the Dorsetshire (70 guns), on the home station and in the Mediterranean, from 1760 to the peace in 1763. He was admitted as a fellow of the Royal Society on 24 May 1764 (and was one of its Visitors to the Royal Observatory, Greenwich, from March 1765), before being one of those the Board of Longitude asked to 'number-crunch' the results of the 1764 second sea-trial to Barbados of John Harrison's longitude watch. From about 1764 he commanded the royal yacht Mary, later moving to the HMY Royal Charlotte, a command he retained until promotion to rear-admiral of the blue on 23 January 1778.
Then, in March 1778, he was chosen by his old friend Admiral Keppel (now in command of the Channel Fleet), to be "captain of the fleet" and effectively chief of staff in HMS Victory, which commissioned in May 1778 as Keppel's flagship. (Campbell was Victory's "1st captain", whilst Captain Jonathan Faulknor was her "2nd Captain".) As such, he took an important part in the battle of Ushant on 27 July, was warmly recommended to the king by the first sea lord Lord Sandwich, and remained in the role until the end of 1778.
However, Campbell was offered no further commands until April 1782, when Keppel became Sandwich's successor as first sea lord, and appointed Campbell (now a vice-admiral of the white), governor and commander-in-chief of Newfoundland; Campbell sailed there in HMS Portland (50 guns) on 17 June 1782. On 25 June, the Portland and another 27 ships were intercepted by the Franco-Spanish combined fleet commanded by Luis de Cordova. Although 18 vessels were captured, HMS Portland and nine ships managed to slip away. He held this post from 1782 to his death in London in 1786.
During this time he returned to England periodically, allowing him in 1784 and 1785 - at Hans Moritz von Brühl's request - to arrange trials of Thomas Mudge's first chronometer on his passage to and from England and in Newfoundland (borrowing an achromatic telescope from the Board of Longitude to ascertain Newfoundland's longitude). Also, as a result of Campbell's proclamation of religious freedom for all inhabitants of Newfoundland, James Louis O'Donel authorized the construction of a Catholic chapel.
He was married, but his wife's name does not survive.
