Life

Bläsing was the son of a tin caster in the old town of Königsberg and had attended the old town school. On October 11, 1678, he enrolled at the University of Königsberg. Here he attended the lectures of Andreas Hedio and Laurentius Weger in philosophy, heard the mathematical lectures with Georg Wosegin and Bartholomäus Goldbach , attended medical lectures with Georg Rast and had found another teacher in the theologian Georg Damm , with whom he lived promoted him. After he had acted as a response to the Disputation de verbo Dei under Weger in 1682 , he traveled to a number of German cities and met at the University of Leipzig , where he obtained the Baccalaureate and on January 25, 1683 the academic degree of Magister in Philosophy.

After more than a year he left Leipzig after completing the disputation de erronea temporis mensuratione in itinere (Leipzig May 3, 1684), returned to Königsberg and, after being appointed to the philosophical faculty, took part in university operations. As the successor to Georg Wosegin , he received the professorship of mathematics on May 2, 1690, which position he took on November 14 with the Astronomical Disputation de Mercurii per solem transitu the November Xth. Ac observando started . After a few years, in 1697 he was granted a trip through Germany, Holland, England and France, where he got acquainted with the most famous mathematicians of his time.

In 1699 he worked again in Königsberg. On March 11, 1701 he became a member of the Academy of Sciences in Berlin and in 1703 Senator of the Academy and inspector of the alumni. Bläsing also took part in the organizational tasks of the Königsberg University. He was several times dean of the philosophical faculty, 1708 prorector and 1714 rector of the alma mater . He was now widowed and had no descendants. On May 3, 1716, he donated 1000 Reichstaler for a scholarship, called Mathematicum Blaesingianum , with the stipulation that a mathematics student would receive 30 Reichstaler from the interest for four years and that a sum of money should be saved from the surplus for another scholarship .

In his will, he had decreed that his collection of 3,000 books should be sent to the university library and that the philosophy faculty should preserve his garden and the buildings belonging to it. Its mathematical instruments, a coin collection, a small natural history cabinet and a collection of various antiques should also be given to the university. His coin collection bequeathed to the university formed the basis for a first academic coin collection. He used his silver and other household items for a church and for sale to the poor. After his death, his body was buried on October 14, 1719 in the professors' vault of Königsberg Cathedral .
