The Slowinski family, Slowinski Company is one of the oldest feather companies in Poland.

As early as the 1930s. Stanislaw Slowinski, son of Szczepan, traded in feathers. After World War II in l. 1950s, 1960s. Stanislaw's sons, Wladyslaw and Zenon traded feathers, as well as Stanislaw's daughters, Klara with her husband Henryk Szaszkowski, Regina with her husband Wladyslaw Pilarski, and later their son, Andrzej Pilarski. Throughout his life, Zenon Slowinski delivered feathers to the feather purchase at GS in Sompolno and GS Ślesin. However, the most famous person in the industry was Wladyslaw Slowinski. He was one of the few in Poland to have a so-called. "sapphires," i.e., to put it in Slesian terms, permission to trade in feathers throughout the country. This enabled him to supply feathers, among other things. to a cooperative in Wozniki Slaskie, in Chorzow, to a feather factory in Cracow, where Mr. Wróbel was the director, to Lublin, where Mr. Lenartowicz was the director. It should be added that in those days only a few people in Poland could buy feathers nationwide. In addition to Wladyslaw Slowinski, such credentials boasted, among others. Mr. Pietryga from Zloczew, Kutwal, Twardochy from Katowice, the Kaminskis from Lodz and two people from Kielce.

In 1989. Jerzy Slowinski and Stanislaw Wojciech Wozniak are opening ELESCO in Slesin, where they are training a new cadre of feather buying agents. Dozens of people have been trained. These people were employed by ELESCO and obtained permits to trade in feathers nationwide. The vast majority of these adepts today own their own quilting businesses. Many of them are leading feather exporters. ELESCO is one of the first private companies in Poland to obtain a license from the Chamber of Foreign Trade to export feathers and down to other countries. And so it was possible to export goose down for the first time to Japan, specifically to Tokyo, later to Germany, Austria, Norway. Quilts and pillows were also sewn at ELESCO. They exhibited at the fair In Poznan, Graz (Austria), Mechelen (Belgium).

Due to the high demand for feathers on the market, Jerzy Slowinski and Stanislaw Wozniak open a Polish company in Mogilev, Belarus, under the name MAGIPOL. MAGIPOL exported slaughter feathers from the Borysew slaughterhouse, which was a shareholder of the company. MAGIPOL organized training courses on plucking goose feathers from live birds on a farm in Borysewo conducted by a group of professionals from Zagórowo (Konin). In addition, both Belarusians and Ukrainians were taught to classify feathers. Participants in the training include. Valery Starovoytov, Bagirotsov, Romanenko, and Sergei Mashin, who can be said to have taught the feather trade to the whole of Sumy and Ukraine. MAGIPOL was only allowed to export to Poland slaughter feathers from state-owned slaughterhouses. Sergey Maszyn and Romanenko opened the first private company in Belarus that was allowed to export feathers to Poland, to the "SLOWIÑSCY" company owned by Jerzy I Romualda Slowinski. Today, the students of Magipol and Sergey Machine have sizable quilting plants in Sumy and throughout Ukraine.

In 1992. Jerzy Slowinski and his wife Romualda are starting a separate business. The company "SŁOWIŃSCY" imports feathers and down from all over Europe, and exports worldwide. Today, it is a modern plant equipped with very good machinery that is fully computerized. Annually, 500-700 tons of duck and goose feathers and down are processed here. The company has strong growth opportunities, which depend on successors and their expansion.
