Slightly shorter life had active in Sielce, in years 1839-1861 snuff factory, founded by financier and industrialist and shareholder of hiring tobacco monopoly - Leopold Kronenberg (1812-1878), who owned at that time manor and palace in Sielce. Emil Hignet (1817-1887), an official Censorship Committee, ran along with his brother Julian, the country's first Department of Silkworm Breeding and silk spinning factory - all placed on a lot separated from the manor, the center which occupied "Bogucin" villa. Existing nearby horticultural farm Bardet brothers (of French origin) supplied them with mulberry bushes.

Cigars from Sielce
As many as half thousand workers employed founded in the mid-nineteenth century Snuff Factory in Sielce. It was the first large industrial plant built on the Warsaw suburb. He was only a few dozen meters from the present headquarters of "Gazeta Wyborcza". He stood on the north (odd) side of the present-day Chelmska bearing then the name Książęca road - roughly where today's Lwicka street outlet is. The factory belonged to Leopold Kronenberg. Buildings went around a large, square courtyard, on which smaller buildings had place.
At the cigars curling mainly women and additionally young boys were hired. Working conditions were harsh. Factory premises were so tight that the workers were forced to sit for a few hours next to ladle of the toxic fumes. Women complained of persistent headaches, dizziness and nausea. In 1860 Kronenberg, who managed to get rid of quite cumbersome shareholders, moved the factory to a new, specially designed buildings at Marszałkowska street.
