Fritz Friedlaender-Fuld (30/08/1858 in Gliwice – 16/07/1917 in the castle Lanke near Berlin). The son of a very famous Jewish entrepreneur Emanuel Friedlaender and his wife Anna.
In 1875, he started working in the family company, which traded coal. In 1880, with his father’s death, he became its chairman. He was only 22.
In 1883, after some troubles connected with the crisis on the coal trade market, he opened a new cocking plant by the pit shaft „Poręba” in Zabrze. By that he realized his father’s plan to develop the company, which was to develop cocking industry in Upper Silesia and gain some by-products from black coal. To make the production process better, Friedlaender brought some specialists from Westphalia. After two years of trials and experiments, combustible coke of good quality was produced, tar and ammonia. At once another cocking plant in Zabrze, namely “Skalley”, was opened. In 1890 it changed its name into "Oberschlesische Kokswerke und Chemische Fabriken". In 1891, the first benzol factory in Upper Silesia was opened by the foundry "Julia" in Bobrek.
At the same time, Fritz Friedlaender was engaged in exploiting black coal in the district of Rybnik. As early as in 1872, his father bought the first mining districts in the district of Rybnik . Now, his son, Fryderyk, bought some mines, namely “Emma" (today’s “Marcel”), “Rymer”, “Anna” and many yet not exploited mining fields. They were underinvested and old fashioned then. The yearly total coal output was circa 200,000 tonnes. Friedlaender wanted to renew mining fields. He built housing estates for the workers near the mines. In 1903, he established the Coal Communitas Fovae in Rybnik (Rybnickie Gwarectwo Węglowe), which employed 13,000 workers in the 1920s. The yearly coal output was then 2.5 million tones and 200,000 tonnes of coke. Moreover, Friedlaender was the owner of the mine “Eminenz” near Katowice, metal factories "Handtke" in Częstochowa and textile factories in Opole. Creating new nitrogen plants in Chorzow in 1916 and a new plant for carbide production by the mine „Prinz” in Pszczyna were especially important for him. Friedlaender invested not only in Upper Silesia but also he was the owner of the company “Braunkohlen – und Brikett – Industrie A.G.” in Łuzyce (5,000 workers) and was engaged in the ores mining in Norway. The information concerning his death was honored by the aldermen of Gliwice by standing up. [[refr:"nazwa"|B.
