Friedrich Heinrich Albert Wangerin

Friedrich Heinrich Albert Wangerin ( born November 18, 1844 in Pommern in Pomerania, † October 25, 1933 in Halle) was a German mathematician.

Life

Wangerin was the son of Master Plumbers Heinrich Wangerin and his wife Emilie Bathke. In the years 1853-1862 Wangerin attended the grammar school of his native city. Easter 1862 he held as the best student's acceptance speech of high school graduates in the Greek language.

Right after that, he began to mathematics and physics at the University of Halle to study. In the main, were Professors Eduard Heine and August Rosenberger his teachers. 1864 moved Wangerin for two years after Königsberg. There he studied primarily with Professors Franz Ernst Neumann and Friedrich Julius Richelot. On March 16, 1866 Wangerin doctorate at Neumann with the thesis De annulis Newtonianis. At the same time he was also qualified as a teacher.

He was then employed as a teacher on probation at the trade school Friedrichswerder in Berlin on 1 April 1866. This sample time he was on 31 March 1867, with effect from 1 April of the same year as an assistant teacher at Stralauer upper middle school (later Andreas Real Gymnasium), also in Berlin, employed. He held until September 30, 1868 this office.

From October 1, 1868 to March 31, 1869, he worked as a regular teacher at the secondary school 1st class in Poznan. During this time, Wangerin has also served as editor of the yearbook on the progress of mathematics. In April, he went back to Berlin and was until March 31, 1876 worked as a teacher at the St. Sophia Secondary School in Berlin.

On April 14, 1871, he married Johanna Dorn in Berlin. With her he had two daughters and four sons.

With effect from March 2, 1876 Wangerin was appointed associate professor of mathematics at the University of Berlin. Here Wangerin had merit, by holding lectures for students on a regular basis. Six years later, on March 29, 1882 Wangerin became a full professor of mathematics at the University of Halle, where he became the successor of his teacher Eduard Heine.

On June 15, 1883 Wangerin was admitted to the Imperial Leopoldine Carolinian Academy of Sciences ( Leopoldina ). When August Rosenberger died in 1891, was entrusted Wangerin as a successor to lead the University Observatory in Halle.

That Wangerin was also politically active, you can see on his election to the council of Giebichenstein on May 18, 1892. On November 2nd of the same year he was appointed member of the mining authority to hall. As such, he had to consider future mountain trainee.

On January 18, 1896 Wangerin was awarded the Red Eagle Order 4th class. 1904 Wangerin joined as a corresponding member of the Academy of Sciences in Erfurt profit. As such, he was elected on March 28, 1906 President of the Leopoldina. On 24 May 1907, the Uppsala University honored him with an honorary doctorate. Between winter semester 1910 and 1911 he served as rector of the University Hall 215. On August 24, 1911 Wangerin was honored with the Order of the Crown 3rd class.

With effect from September 30, 1919 Wangerin was given emeritus status and health reasons he stepped on September 8, 1921, as President of the Leopoldina. His successor was August Gutzmer. On February 19, 1922, the Company appointed him an honorary member and awarded him the medal Cothenius.

As a mathematician, he was concerned with potential theory, spherical functions and differential geometry. In the series of Ostwald classics he published several historical mathematical and physical works.

His final resting place he found on the North Cemetery. 1989 his tomb was disbanded and reassigned.
