Carl Canzler

Carl Canzler (born August 28, 1858 in Lippstadt , † January 19, 1919 in Düren ) was a German industrial apparatus manufacturer.

family

Carl Canzler came from a family whose ancestors have been working as farmers or soldiers in Thuringia since the 15th century. His father Friedrich August (1825–1868) was a hussar stick trumpeter and later a sexton at St. Mary's Church in Lippstadt . His mother Josefine Höhne was a teacher from Westphalia. The paternal grandfather named Johann Andreas was a schoolboy and judge in Schafau .

Canzler himself married a woman named Margarete (* 1864). Her father Heinrich Friesdorf was a farmer in Herrig and came from a Rhenish farming family. From this marriage came the son Heinrich, born in 1888, who, as a graduate engineer, took over and managed his father's company. The Technical University of Karlsruhe made him an honorary senator in 1952.

Live and act

Canzler completed a four-year apprenticeship with a master coppersmith in Lippstadt. In 1877 he passed the journeyman's examination according to the rules of the guild. After years of wandering, he began studying at the Tecnikum Buxtehude in 1885. He passed the master craftsman's examination and took part in Berlin in 1888 as a delegate at the founding meeting of the union of coppersmiths in Germany. Two years later, with the help of his wife, he opened his own coppersmith's shop in Elsdorf . In 1894 he went to Düren with the smithy .

In the following years, Canzler undertook experiments and trials and worked with engineers and chemists of his clients on process technologies. During this time he made inventions in a wide range of subjects. In the area of ​​apparatus engineering, Canzler played a pioneering role in the introduction of gas fusion welding and the perfection of practical implementation. In the field of iron welding, new processes quickly showed satisfactory results and were widely used in industry and craft. However, the welding of copper caused enormous problems due to technological and metallurgical conditions. As a researcher, Canzler busily and stubbornly dealt with these difficulties and thus invented the "process for autogenous welding of copper, using a phosphorus-containing copper wire as an additive, characterized in that silver is added to the additive material", for which he received a patent in 1912 . This gave rise to the so-called “Canzler wire”, which enabled copper to be welded and produced acid-resistant seams.

When he died, Canzler left a company with around 40 employees. His son expanded it into the world-famous Canzler factories .
