Description of (scientific/cultural/natural) heritage
The Royal Stables (Marstall) for 200 horses were erected in 1687/88 by Johann Arnold Nering (1659--1695) as Kurfürstlich-Brandenburgischer Oberbaumeister (Electoral Brandenburg master builder). The building was raised by one floor in 1695 to 1697 for the Academy of Arts.
As a replacement for the wing "Unter den Linden", that burned out in 1743, Johann Boumann d.Ä [Jan Bouman]. (1706--1776) built from 1747 to 1749 a new building. In its Western part, moved the Academy of Sciences (demolished in 1903), in the Eastern part (demolished in 1908) moved the Academy of Arts.
As an extension of the Royal Stables to the double size, the Academy Observatory was built from 1696 to 1700 by the architect Martin Grünberg (1655--1706/07), successor of Nering.
This ("old Berlin Observatory") or Academy Observatory, was initiated by Gottfried Wilhelm (von) Leibniz (1646--1716) in 1700 when he initiated the "Kurfürstlich Brandenburgische Sozietät der Wissenschaften" (Electoral Brandenburg Society of Sciences), which would become in 1701 the Royal Prussian Society of Sciences, and in 1744 the Royal Academy of Sciences. Under Wilhelm von Humboldt (1767--1835) it was renamed Royal Prussian Academy of Sciences (Königlich-Preußische Akademie der Wissenschaften zu Berlin), since 1992 Berlin-Brandenburgische Akademie der Wissenschaften.
Friedrich III. (1657--1713), Elector of Brandenburg, 1688 to 1713, officially founded the Academy on July 11, 1700 and appointed its initiator Leibniz as the first president. Friedrich III. became as Friedrich I. the first King in Prussia from 1701 to 1713. The Electoral Brandenburg Society of Sciences (Academy of Sciences) was divided into four classes: 1. physics, medicine, chemistry, 2. mathematics, astronomy, mechanics, 3. development of the German language, 4. literature.
After the demolition, Ernst Eberhard von Ihne (1848--1917) built a new complex in the square Unter den Linden, Charlotten-, Dorotheen-, Universitätsstraße (1903--1914). This new building exists until today as State and University Library with the Library of the Berlin-Brandenburg Academy of Sciences.
The First Astronomers
The famous astronomer and director of the observatory was Gottfried Kirch (1639--1710), the first ’Astronomer Royal’ in Berlin from 1700 to 1710. He had studied at the University of Jena, and had received training in astronomy by Johannes Hevelius. In 1680, he discovered a comet - Comet C/1680 V1 - the first by using a telescope. In 1681, he discovered the open star cluster M 11. In 1786, he found the Mira variable ¤ç Cygni. He also devoted a lot of time for observing the variable star Mira (Wunderstern am Hals des Walfisches. Leipzig 1678). His main task was creating Almanacs and Calendars, already before he became director in Berlin. The Almanacs helped to distribute the ideas of the Enlightenment and Pietism to the public.
The first observations in the observatory tower could be made in 1706 with moveable instruments and a clock (Stutzuhr). The astronomer lived in Dorotheenstrasse 10. Gottfried Kirch died one year before the observatory was ready (1711).
Kirch’s second wife Maria Margaretha Kirch-Winkelmann (1670--1720), married in 1692, was also active as an astronomer. Maria Margaretha worked in the household of the farmer and astronomer Christoph Arnold (1650--1695) in the village of Sommerfeld, where she acquired basic knowledge and experience in the field of astronomical observations and meteorology, later she was further trained by Gottfried Kirch. Maria Margaretha Kirch-Winkelmann assisted in observations and to run calculations. While observing the comet of 1702 together, he discovered the globular cluster M 5.
Other female astronomers of the 17th century were Maria Cunitz, Elisabeth Hevelius, and Maria Clara Eimmart.
Maria Margaretha Kirch-Winkelmann is considered the first woman to discover a comet (Comet C/1702 H1):
"Early in the morning (about 2:00 AM) the sky was clear and starry. Some nights before, I had observed a variable star and my wife (as I slept) wanted to find and see it for herself. In so doing, she found a comet in the sky. At which time she woke me, and I found that it was indeed a comet ... I was surprised that I had not seen it the night before."
(Notebooks of Gottfried Kirch, quoted after Helly & Reverby 1992)
She also made observations of the variable star Mira Ceti.
In 1709, Gottfried von Leibniz presented her to the Prussian court, where Maria Margaretha Kirch explained her observations of sunspots:
"There is a most learned woman who could pass as a rarity. Her achievement is not in literature or rhetoric but in the most profound doctrines of astronomy ... I do not believe that this woman easily finds her equal in the science in which she excels... She favors the Copernican system (the idea that the Sun is at rest) like all the learned astronomers of our time. And it is a pleasure to hear her defend that system through the Holy Scripture in which she is also very learned. She observes with the best observers and knows how to handle marvelously the quadrant and the telescope." (quoted after Helly & Reverby 1992)
After the death of her husband, she was not accepted by the academy and was not paid for her continuing work, inspite of the fact that the new director Johann Heinrich Hoffmann (1669--1716) was not really able to do successful work. Finally in 1712, Kirch gave up and accepted the patronage of the amateur astronomer Baron Bernhard Friedrich von Krosigk (1656--1714), who had since 1706 a private observatory in Wallstrasse 72, Neu-Cölln. After the death of Krosigk, Kirch moved to Danzig from 1714 to 1716. Then she calculated calendars in her home in Berlin for Nuremberg, Dresden, Breslau (Wroclaw), and Hungary.
Maria Margaretha had also trained her son and her daughters, especially Christine Kirch (1697--1782) and Margaretha Kirch (~1703-- after 1744), who became active in astronomy. Her son Christfried Kirch (1694--1740) was called as director from 1716 to 1740.
The Calendar Privilege and the Protestant Calendar Reform
As an income for the observatory and the salary of the director, Friedrich III introduced through an edict a monopoly for calendars in Brandenburg, and later Prussia, imposing a calendar tax. The basic idea came from Erhard Weigel (1625--1699), professor of mathematics at the University of Jena, who had proposed a similar calendar privilege for a Germany-wide Academy. The academy’s calendar privilege expired in 1811 in the course of Wilhelm von Humboldt’s reforms.
The Academy of Sciences in Berlin handled sales of their calendars.
The introduction of an "Improved Calendar" (Gregorian Calendar)
The Protestants did not grant the Pope the right to reform the calendar and initially retained the old "Julian calendar". It was not until September 23, 1699 (Julian, October 3 Gregorian) that the Protestant Imperial Estates decided at the Perpetual Diet of Regensburg to introduce an "Improved Calendar" from 1700 onwards. They practically adopted the Gregorian Calendar to count the days and therefore omitted 11 days (February 19 to 29, 1700).
However, Easter (on the first Sunday after the first full moon after the beginning of spring) should be determined in an astronomically correct way (and not approximately according to the Easter algorithm). This is the reason for the founding of the Academy Observatory with an astronomer for calculating the calendar.
In 1768, the Academy Observatory received a mural quadrant made by John Bird of London; this was the first really important observing instrument, which is preserved in Babelsberg Observatory.
The Academy Observatory was used until the New Observatory or "Königliche Sternwarte zu Berlin" (Royal Observatory Berlin) was built in 1835 as University Observatory.
History
The Berliner Astronomisches Jahrbuch (for 1776), already published in Berlin 1774, initiating the longest-lasting publication series in astronomy -- until 1959.
Akademische Sternkarten - Academic Star Charts
The so-called Akademische Sternkarten (Academic Star Charts) cover Zone Hora 0 - Hora XXIII, Blatt 1-24 for the epoch 1800. They were observed since 1830 by many observers in different countries (see list), engraved by Auguste Kolbe:
Verzeichniss der von Bradley, Piazzi, Lalande und Bessel beobachteten Sterne in dem Theile des Himmels zwischen 2h56’ bis 4h04’ gerader Aufsteigung, und 15° südlicher bis 15° nördlicher Abweichung, berechnet und auf 1800 reducirt. Berlin: Gedruckt in der Druckerei der Königlichen Akademie der Wissenschaften, in Commission in F. Dümmler’s Verlags-Buchhandlung, 1830--1858. (Wolfschmidt 2022).
International collaboration between leading astronomers aimed to find the missing planet between Mars and Jupiter (Wolfschmidt 2020). To realize this, the sky had to be divided into 12 zones. Every two members were assigned one of the 12 zodiac constellations for the search; they had to create an exact map with stars up to 9th magnitude. After the well-known discovery of the first four planetoids Ceres (Piazzi 1801), Pallas (Olbers 1802), Juno (Harding 1804), and Vesta (Olbers 1807), the acticity with the compilation of the star maps made no considerable progress. However, since the astronomers expected further discoveries of planetoids, Friedrich Wilhelm Bessel (1784--1846) made an important proposal to the Berlin Academy of Sciences in 1824, to offer a bonus for each completed map. After 35 years, Johann Franz Encke (1791--1865) was finally able to present the complete Berlin Academic Star Charts to the Academy in 1858.
Station 1 of the Prussian Optical Telegraph, used between 1832 and 1848
The Marstall (Royal Stables), Unter den Linden and Dorotheenstrasse, had been erected from 1687 to 1688 according to the plans of the architect Johann Arnold Nering. From 1696 to 1700, Martin Grünberg extended the complex northwards (Dorotheenstrasse) for the new Societät der Wissenschaften.
From 1700 until 1711, the observatory, a 27-meter-high tower of three storeys, built by Grünberg, was added to the northern wing as observatory with a platform for the long telescopes.
This first Berlin observatory, the Marstall, the Academy Observatory was a tower observatory like several in the 18th century.
The New Royal Observatory in Berlin was built in 1835.
