\"max-ulrich-schoop\"<\/a>Max Ulrich Schoop (born April 10, 1870 in Frauenfeld, Switzerland; died February 29, 1956 in Zurich, Switzerland) was a Swiss inventor who introduced the metal spraying process in 1906 and developed various aluminum welding processes. Schoop obtained a patent to flame-spray metal onto a board through a patterned mask, which led others to find new ways to create printed circuit boards.<\/span><\/span> <\/span><\/p>\n

His father, Ulrich Schoop, moved from Dozwil to Frauenfeld in 1863, where he worked as a drawing teacher.<\/span><\/span> 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.<\/span><\/span> <\/span><\/p>\n

Max Ulrich’s brothers were the electrochemist Paul Schoop (around 1858\u20131907) and the journalist Friedrich Maximilian Schoop (1871\u20131924), who, together with his wife Emma, had the children Max (1902\u20131984; Trude Berliner)<\/span><\/span>, Trudi, Hedi (1906\u20131995 ceramist; Friedrich Hollaender and Ern\u00f6 Verebes) and Paul (1907\u20131976; composer).<\/span><\/span> Emma followed her children to California in the 1930s.<\/span><\/span> <\/span><\/p>\n

Max Ulrich Schoop graduated from school in Zurich and, in 1885, began training in graphics at Wilhelm Cronenberg’s institute in the Allg\u00e4u.<\/span><\/span> Back in Switzerland, he worked as an assistant to a photographer and in La-Chaux-de-Fonds as a portrait retoucher.<\/span><\/span> <\/span><\/p>\n

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

In 1895 he began studying physics and electrical engineering at ETH Zurich.<\/span><\/span> Soon he was working again in the accumulator business at Sch\u00f6ller in Vienna and as head of the laboratory at Hagen in Cologne.<\/span><\/span> <\/span><\/p>\n

On August 23, 1898, he married Martha B\u00e4chler, with whom he had five children.<\/span><\/span> When his son Uli Schoop was born in 1903, he was employed as head of the laboratory at the Accumulator Works in Cologne.<\/span><\/span> The family moved to Paris the same year, where he worked as a laboratory manager for the automobile manufacturer Dinin.<\/span><\/span> <\/span><\/p>\n

In 1903, Schoop went to Paris to join the Dinin automobile manufacturer, where, as Laboratory Chief, he succeeded in autogenous aluminum welding after 800 attempts.<\/span><\/span> In 1907 he traveled to the USA to market his aluminum welding invention, which ended in a business fiasco.<\/span><\/span> <\/span><\/p>\n

In the spring of 1909, he watched his children shoot “lead bullets” in the Bois-Colombes park.<\/span><\/span> A lead coating had formed on the garden wall where the lead bullets splattered.<\/span><\/span> Schoop then undertook experiments with small cannons, tin, and lead granules (metal grains obtained by granulation).<\/span><\/span> On April 28, 1909, he registered his basic patent for the metal spraying process in Berlin, granted four ye<\/span><\/span><\/span><\/p>\n

ars later.<\/span><\/span> Patent disputes followed, so his patent was only awarded after six years in the last instance at the Reichsgericht in Leipzig.<\/span><\/span> <\/span><\/p>\n

In 1910 Schoop returned to Zurich and opened his laboratory, where he further developed thermal spraying.<\/span><\/span> To finance this, he founded two companies that manufacture Schoop’s metal spray guns and, on the other hand, offered contract metallization.<\/span><\/span> The technical manager of the works for metallization Franz Herkenrath was helpful.<\/span><\/span> “Metal spraying, invented by the Swiss Max Ulrich Schoop, is any thermal process in which metals in powder or wire form are melted, atomized simultaneously, and sprayed onto a suitably prepared surface.” In March 1919, Schoop had a patent<\/span><\/span> from his colleague Frieda Neininger.<\/span><\/span> Among other things, the contacting of the end faces of film capacitors are based on his process.<\/span><\/span> <\/span><\/p>\n

In 1914 he received the John Scott Medal from the University of Philadelphia.<\/span><\/span> The Technical University of Braunschweig awarded him a doctorate.<\/span><\/span> <\/span><\/p>\n

After his divorce in 1927, he married his colleague Neininger on December 21, 1929.<\/span><\/span> Since none of his children could or wanted to continue his work, Schoop liquidated his laboratory in 1945<\/span><\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
