Engelbert Arnold

Engelbert Arnold (born March 7, 1856 in Schlierbach , Canton Lucerne ; † November 16, 1911 in Karlsruhe ) was a Swiss electrical engineer . He was the first full professor at the Electrotechnical Institute of the Grand Ducal Technical University in Karlsruhe (Chair for Power Engineering and Electrical Machines), which was built between 1896 and 1898 under his leadership.

Life

Electrotechnical laboratory at the Technical University of Karlsruhe around 1899

He was the son of a farmer, had eight siblings and attended grammar school in Beromünster . From autumn 1874 to 1878 he studied at the Eidgenössisches Polytechnikum in Zurich , which he graduated from with a degree in mechanical engineering. As a reward, he was allowed to attend the Paris World Exhibition in 1878 . After brief internships in Leipzig and Offenbach, he became assistant to Carl Ludwig Moll at the Riga Polytechnic in 1880 . In 1883 he completed his habilitation and became a private lecturer in mechanical engineering and electrical engineering. He also founded the Russian-Baltic electrotechnical factory for the construction of dynamos there around 1888 with the optician Heinrich Dettmann . With his textbook "The armature windings and armature constructions of direct current dynamo machines" (Springer, 1896) he became famous. After Charles Eugene Lancelot Brown retired as chief electrician at Maschinenfabrik Oerlikon in 1891 , Arnold was his successor. He analyzed and improved the repulsion engine .

In 1892 he married Helen Moll, the daughter of Carl Ludwig Moll. He lived with her at Weinbergstrasse 14 in Zurich. In 1899 a daughter was born.

In 1894 he was appointed professor at the Grand Ducal Technical University in Karlsruhe . From 1899 to 1904 he built the electrotechnical laboratory. With his assistant, the Dane Jens Lassen La Cour, he wrote the multi-volume textbook series "Die AC Technology" .

In 1905 he was appointed Privy Councilor and in 1906 an honorary doctorate from the Technical University of Hanover . In Karlsruhe he became rector in the academic year 1906/1907. In 1911 Arnold Rudolf Richter offered an extraordinary professorship at the Karlsruhe University of Applied Sciences, but died on November 16, 1911, before he could take up the position. Rudolf Richter took over the management of the Electrotechnical Institute in 1912 as the successor to Engelbert Arnold.
