Lorentz Eichstadt
Eichstaedt Lorenz ( born August 10, 1596 Stettin, † June 8, 1660 in Danzig) was a German physician and astronomer.
Eichstaedt was the son of the Szczecin businessman Peter Eichstaedt and his wife Anna, daughter of councilor Peter Mathias from Gollnow in Pomerania. After attending the Gymnasium in Stettin, he studied at 1612/1613 in Greifswald, then from 1614 in Wittenberg at Daniel Sennert. In the period 1617-1619 he studied at various universities in Germany and Holland, then practiced from 1619 at the physician David Faber in Altenburg. 1621 he received his doctorate in Wittenberg and then settled as a physician in Stargard in Pomerania. In 1624, he was - only 24 years old - Stadtphysicus in Szczecin. In 1628 he married Catherine Giese, the daughter of the Szczecin Mayor Paul Giese. From this marriage six children, four sons and two daughters went out. In the years 1633 and 1640 Eichstaedt traveled to Holland, there to maintain his scientific contacts. After over 20 years working in Stettin, he was appointed in 1645 as city physician and professor of medicine, mathematics and physics at the Academic Gymnasium to Gdansk, where he worked until the end of his life.
In Danzig, he met the then young and unknown astronomer Johannes Hevelius, for whose 1647 he wrote a poem published Selenographia in Latin hexameters, which was printed with the work. Eichstaedt had in Stargard an astronomical work on a conjunction of the planets Jupiter and Saturn wrote, which was published in 1622 in Szczecin. In the following years, further works both medical and astronomical objects appeared, concerning the most important of which were published the 1634-1644 ephemeris. These were tables where for the use of geographers, navigators and astronomers predicted positions of the planets were listed. They continued the famous, started by Johannes Kepler, published in 1627 Rudolfine Tables.
He was buried on 14 June 1660 in the Gdansk Trinity Church.
The lunar crater calibration city is named after him.
