Briefly, he also was a paramilitary leader, known for organizing the Polish Silesian Uprisings in Upper Silesia, which after World War I was contested by Germany and Poland. Korfanty fought to protect Poles from discrimination and the policies of Germanisation in Upper Silesia before the war and sought to join Silesia to Poland after Poland regained its independence.

Jan Czochralski ( YAN chokh-RAHL-skee, Polish pronunciation: [ˈjan t͡ʂɔˈxralskʲi]; 23 October 1885 – 22 April 1953) was a Polish chemist who invented the Czochralski method, which is used for growing single crystals and in the production of semiconductor wafers. It is still used in over 90 percent of all electronics in the world that use semiconductors. He is the most cited Polish scholar.There is evidence that Czochralski sheltered two Jewish women in his home until the Warsaw Uprising to save them from the Germans and some evidence that he was instrumental in financially helping a previously owned Jewish business in the ghetto.

Zora Arkus-Duntov (December 25, 1909 – April 21, 1996) was a Belgian-born American engineer whose work on the Chevrolet Corvette earned him the nickname "Father of the Corvette.": 6  He is sometimes erroneously referred to as the inventor of the Corvette, whereas that title belongs to Harley Earl.

Hugo Junkers (3 February 1859 – 3 February 1935) was a German aircraft engineer and aircraft designer who pioneered the design of all-metal airplanes and flying wings. His company, Junkers Flugzeug- und Motorenwerke AG (Junkers Aircraft and Motor Works), was one of the mainstays of the German aircraft industry in the years between World War I and World War II. His multi-engined, all-metal passenger- and freight planes helped establish airlines in Germany and around the world.
In addition to aircraft, Junkers also built both diesel and petrol engines and held various thermodynamic and metallurgical patents. He was also one of the main sponsors of the Bauhaus movement and facilitated the move of the Bauhaus from Weimar to Dessau (where his factory was situated) in 1925.
Amongst the highlights of his career were the Junkers J 1 of 1915, the world's first practical all-metal aircraft, incorporating a cantilever wing design with virtually no external bracing, the Junkers F 13 of 1919 (the world's first all-metal passenger aircraft), the Junkers W 33 (which made the first successful heavier-than-air east-to-west crossing of the Atlantic Ocean), the Junkers G.38 "flying wing", and the Junkers Ju 52, affectionately nicknamed "Tante Ju", one of the most famous airliners of the 1930s.
When the Nazis came into power in 1933, they requested Junkers and his businesses aid in the German re-armament. When Junkers declined, the Nazis placed him under house arrest in 1934 and eventually seized control of his patents and company. He died the following year. Under Nazi control, his company produced some of the most successful German warplanes of the Second World War.
