Apianus on an 18th-century engraving

Petrus Apianus (April 16, 1495 – April 21, 1552), also known as Peter Apian, was a "German "humanist, known for his works in "mathematics, "astronomy and "cartography.[1]

The lunar crater "Apianus and asteroid "19139 Apian are named in his honour.[1]


Life and work[edit]

He was born as Peter Bienewitz (or "Bennewitz) in "Leisnig in "Saxony; his father was a "shoemaker. The family was relatively well off, belonging to the middle-class citizenry of Leisnig. Apianus was educated at the "Latin school in "Rochlitz. From 1516 to 1519 he studied at the "University of Leipzig; during this time, he Latinized his name to Apianus (lat. apis means "bee"; "Biene" is the German word for bee).

In 1519, Apianus moved to "Vienna and continued his studies at the "University of Vienna, which was considered one of the leading universities in geography and mathematics at the time and where "Georg Tannstetter taught. When the "plague broke out in Vienna in 1521, he completed his studies with a "B.A. and moved to "Regensburg and then to "Landshut.

In Landshut, he produced his Cosmographicus liber (1524), a highly respected work on "astronomy and "navigation which was to see at least 30 reprints in 14 languages and that remained popular until the end of the 16th century. He married the daughter of a councilman of Landshut, Katharina Mosner, in 1526. They would have 14 children together, five girls and nine sons, one of whom was "Philipp Apian.

In 1527, Peter Apian was called to the "University of Ingolstadt as a mathematician and printer. His print shop started small. Among the first books he printed were the writings of "Johann Eck, "Martin Luther's antagonist. Later, his print shop soon became well known for its high-quality editions of geographic and cartographic works.

Through his work, Apian became a favourite of "emperor "Charles V. Charles had praised his work (the Cosmographicus liber) at the "Imperial Diet of 1530 and granted him a printing monopoly in 1532 and 1534. In 1535, the emperor made Apian an "armiger, i.e. granted him the right to display a "coat of arms. In 1540, Apian printed the Astronomicum Caesareum, dedicated to Charles V. Charles promised him a truly royal sum (3,000 golden "guilders)1, appointed him his court mathematician, and made him a "Reichsritter (a Free Imperial Knight) and in 1544 even an "Imperial Count Palatine. All this furthered Apian's reputation as an eminent scientist.

Apian is also remembered for publishing the only known depiction of the "Bedouin constellations in 1533. On this map "Ursa Minor is an old woman and three maidens, "Draco is four camels and "Cepheus was illustrated as a shepherd with sheep and dog.[2]

Despite many calls from other universities, including "Leipzig, "Padua, "Tübingen, and "Vienna, Apian remained in "Ingolstadt until his death. Although he neglected his teaching duties, the university evidently was proud to host such an esteemed scientist. Apian's work included in mathematics—in 1527 he published a variation of "Pascal's triangle, and in 1534 a table of "sines— as well as astronomy. In 1531, he observed a "comet and discovered that a comet's tail always point away from the sun. ("Girolamo Fracastoro also detected this in 1531, but Apian's publication was the first to also include graphics.) He designed "sundials, published manuals for astronomical instruments and crafted volvelles ("Apian wheels"), measuring instruments useful for calculating time and distance for astronomical and astrological applications.

Apian was followed by his son Philipp (1531–1589), who, in addition to his own research, preserved the legacy of his father.[3]

^1 Whether Apian ever received the promised money is uncertain; in any case he wrote a letter to the emperor in 1549 asking him to finally pay the promised sum.[4]
