Friedrich Julius Richelot

from Wikipedia, the free encyclopedia

Friedrich Julius Richelot (born November 6, 1808 in Königsberg i. Pr. , † March 31, 1875 ibid) was a German mathematician and university professor in Königsberg.

Life

Richelot attended the old town high school in Königsberg. In an examination, the 13-year-old student was found to have a good knowledge of the ancient languages, but his poor knowledge of geography was criticized and his mathematical knowledge was declared to be mediocre. Notwithstanding this, he studied mathematics and astronomy from the fall of 1825 . He became a member of the Corps Masovia . As a student of Carl Gustav Jacob Jacobi , he was awarded a Dr. phil. PhD . The dissertation dealt with the division of the circle into 257 equal parts. In September 1832, he became an associate professor . After he had turned down a call to the Ruprecht-Karls-Universität Heidelberg , he was appointed to the chair of mathematics at the University of Königsberg in 1843 . In that year he took over the mathematical department of the Franz Neumann Seminar from Carl Gustav Jacobi, in which Gustav Robert Kirchhoff , Arnold Sommerfeld and David Hilbert , among others, were later trained. In 1848 the students elected him head of the student army composed of various student groups of around 300 men. In 1858/59 he was Vice Rector of the Albertina. Richelot wrote numerous publications in German, French and Latin , including - with his dissertation - one of the first known instructions for constructing the 257-corner with compass and ruler . He died of a heart condition in office at the age of 66 and was buried in the Scholars' Cemetery (Königsberg) . "Loyal friends and grateful students" erected Richelot's tombstone made of dark marble with a bronze round relief. The cemetery was destroyed in 1945. He was married to Pauline geb. Bredschneider. The daughter Clara married the Königsberg physicist Gustav Robert Kirchhoff in 1857. She died in 1869 at the age of 35.
