Conrad Heusler (also Konrad Heusler , born December 22, 1826 , † November 30, 1907 ) was a German entrepreneur and mining official .

Life

Conrad Heusler was the son of the entrepreneur and mining clerk Carl Ludwig Heusler (1790-1851) and his wife Katharina Henriette Elisabeth , née Heeser (1789-1865). He had 2 brothers and six sisters. Conrad Heusler studied mining and metallurgy and then entered the Prussian civil service, where he last worked as Oberbergrat at the Oberbergamt Bonn .

After his father's death in 1851, he joined his older brother Friedrich Wilhelm Otto Heusler (1825–1890), who had taken over the CL Heusler company in Dillenburg as operations manager , as a consultant. The Isabellenhütte started producing nickel silver under the leadership of the two brothers and continued to expand copper production. After the nickel ore deposits of the “Help of God” mine were exhausted in 1869 and the nickel operation at the Isabellenhütte had to be stopped, the company CL Heusler ran into financial difficulties and the joint mine ownership came under bankruptcy administration. The Isabellenhütte ceased operations in 1873. Conrad Heusler then took over all the assets and liabilities of the company CL Heusler in liquidation and he succeeded in putting the company on a new profitable basis through a process for the production of carbonaceous, iron-free manganese, which he fused with copper to form carbon-free 30 percent manganese copper . Heusler's copper manganese alloy showed a seawater resistance that had not been achieved before and subsequently achieved great importance as a screw material in shipbuilding as well as in general mechanical engineering under the trademark "Resistin". The most important application of the manganese-copper alloys came later from 1889 under the name Manganin as a material for electrical precision resistors .
