Heinrich Richard Baltzer

Heinrich Richard Baltzer , called Richard Baltzer, (born January 27, 1818 in Meißen , † November 7, 1887 in Gießen ) was a German mathematician.

Life

Heinrich Richard Baltzer was the son of the professor at the Princely School Meißen Andreas Karl Baltzer and his wife Augusta Charlotta, daughter of Christian Beatus Kenzelmann and Charlotte Christiana Etzler. In 1830 he attended the electoral state school St. Afra in Meißen. In 1836 he began to study philosophical sciences at the University of Leipzig , where he mainly dealt with mathematics and received his doctorate in philosophy on August 1, 1841 . In the same year he became a teacher at the trade school in Chemnitz , in 1842 he became a senior teacher at the Kreuzschule in Dresden and in 1865 he took over a professorship at the same institution.

In 1864 Baltzer became a member of the Saxon Academy of Sciences in Leipzig. He had made a name for himself through book publications. Among other things, he published the first German textbook on determinants . On April 28, 1869, he accepted a call as a full professor of mathematics at the University of Giessen , where he worked as director of the mathematical seminar and the mathematical cabinet until the end of his life.

At the time, he wrote the most popular mathematics textbooks. The second edition of the second volume of his elements of mathematics (1867) contributed significantly to the awareness of the possibility of non-Euclidean geometry in German-speaking countries.

His sons Andreas Eduard Martin Baltzer (born September 7, 1855 in Dresden) and Franz Baltzer (1857–1927) are known from his marriage on June 9, 1854, to Jenny, daughter of the Berlin judge Eduard Gottheiner .
