John Partridge (1644 – c. 1714) was an English astrologer, the author and publisher of a number of astrological almanacs and books.

Life

Partridge was born 18 January 1644 (OS) in East Sheen, Surrey, and died in either 1714 or 1715.

Although starting out in life humbly enough (he was working as a shoemaker in Covent Garden around 1680), Partridge managed to teach himself enough Latin, Greek, Hebrew and astrology to enroll at Leyden University, Holland. He graduated in Medicine and by 1682 was styling himself "Physician to his Majesty". Although he was one of the sworn physicians of the court, he apparently never attended nor received any salary.

Partridge undertook to himself the task of reforming astrology. His program for reform involved eliminating the elements derived for the medieval Arabic tradition in favour of a return to Ptolemy.

Partridge was strongly identified with the Whig faction in seventeenth-century English politics. He was forced into exile in the Dutch Republic during the reign of James II. The reign was also marked by Partridge's feud with his former astrological mentor John Gadbury, who converted to Catholicism. This quarrel spread into a feud with George Parker.

Swift hoax

In the 1708 edition of the Merlinus Almanac, Partridge sarcastically referred to the Church of England as the "infallible Church". This drew the attention of satirist and Church of Ireland cleric Jonathan Swift. Playing on Partridge's own (generally inaccurate) yearly predictions of deaths of notable individuals, Swift, writing under the pseudonym Isaac Bickerstaff, predicted in a letter published in January 1708 that Partridge himself would die an "infallible death" on 29 March that year. On that date, Swift published another letter (purportedly by a "man employed in the Revenue") confirming Partridge's death. The letter was reprinted by other writers and publishers along with its brilliant accompanying eulogy:

Here five foot deep lyes on his back
				A cobbler, starmonger, and quack…
					Who to the stars in pure good-will,
					Does to his best look upward still.
					Weep all you customers that use
					His pills, his almanacks or shoes.

		

When Partridge published a letter proclaiming that he had not in fact died, Swift announced that his letter was false, as "they were sure no man alive ever to writ such damned stuff as this." Partridge's intense unpopularity among Church supporters, those whose deaths he had falsely predicted, anti-Whigs, and those who felt his "astrology" was in reality quackery kept the hoax going long after Swift finally dispensed with it. Partridge reportedly suffered from the effects of the hoax for the rest of his life.
