Max Ulrich Schoop

Max Ulrich Schoop and his second wife Frieda Neininger, before 1957.

Max Ulrich Schoop (born April 10, 1870 in Frauenfeld , † February 29, 1956 in Zurich ) was a Swiss inventor of the metal spraying process.

family

His father Ulrich Schoop had moved from Dozwil to Frauenfeld in 1863 , where he worked as a drawing teacher. In 1876 the family settled in Zurich, where he was awarded the title of professor as a teacher at the Zurich School of Applied Arts .

Max Ulrich's brothers were the electrochemist Paul Schoop (* 1858) and the journalist Friedrich Maximilian Schoop (1871–1924), who with Emma the children Max (1902–1984; ∞ Trude Berliner ), Trudi , Hedi (1906–1995 ceramist; ∞ Friedrich Hollaender and Ernö Verebes ) and Paul (1907–1976; composer). Emma followed her children to California in the 1930s.

Life

Max Ulrich Schoop graduated from school in Zurich and began training in graphics in 1885 at Wilhelm Cronenberg's institute in the Allgäu. Back in Switzerland he worked as an assistant to a photographer and in La-Chaux-de-Fonds as a portrait retoucher.

When his brother Paul was the director of a battery factory in the 1890s, Max Ulrich was sent to the Moscow branch as a fitter in 1893. After surviving appendicitis, he was employed as a tutor for French in Nizhny Novgorod . He also learned Russian and translated works by Leo Tolstoy .

In 1895 he began studying physics and electrical engineering at the ETH Zurich . Soon he was working again in the accumulator business at Schöller in Vienna and as laboratory director at Hagen in Cologne.

On August 23, 1898, he married Martha Bächler, with whom he had five children. When his son Uli Schoop was born in 1903, he was employed as head of the laboratory at the Cologne Accumulatoren-Werke . In the same year the family moved to Paris, where he worked as head of laboratory for the car manufacturer Dinin .

In 1903 Schoop went to Paris to the car manufacturer Dinin , where he succeeded in autogenous welding of aluminum as Chef de Laboratoire after 800 attempts. In 1907 he traveled to the USA to market his invention of aluminum welding, which ended in a business fiasco.

In the spring of 1909 he watched his children shooting flobert in the park of Bois-Colombes . A lead coating had formed on the garden wall where the lead balls splashed. Schoop then undertook experiments with small cannons and tin and lead granules (metal grains obtained by granulation). On April 28, 1909, he registered his basic patent for the metal spraying process in Berlin, which was granted after four years. Patent disputes ensued, so that his patent was only awarded to him after six years in the last instance at the Imperial Court in Leipzig.

In 1910, Schoop returned to Zurich and opened his own laboratory in which he further developed thermal spraying. To finance it, he founded two companies that manufacture Schoop's metal spray guns and also offer contract metallization. The technical manager of the metallization works, Franz Herkenrath, was helpful . “Metal spraying, invented by the Swiss Max Ulrich Schoop, is basically any thermal process in which metals in powder or wire form are melted, atomized and sprayed onto an appropriately prepared surface at the same time.” In March 1919, Schoop granted his colleague Frieda a patent Register Neininger. Among other things, the contacting of the end faces of film capacitors is based on his method.

In 1914 he was awarded the John Scott Medal of the University of Philadelphia. The Technical University of Braunschweig awarded him the Dr. hc

After his divorce in 1927, he married his colleague Neininger on December 21, 1929. As none of his children could and would not continue his work, Schoop liquidated his laboratory in 1945.
