Bolesław Maurycy Wolff (1826–1883), bookseller, printer and publisher. Son of Józef Wolff, a doctor from Warsaw. He was an apprentice in bookstores in Warsaw, Paris, Leipzig, Lviv, Kraków, Vilnius and St. Petersburg. In 1853 he founded an outlay bookshop in St. Petersburg, and in 1856 a printing house. He made his name as a publisher and printer of many Polish literary and scientific works as well as books for children and adolescents. His company included a type foundry. The large Wolff font factory has made special contributions to the development of the Russian civil script. Over a hundred sets of letters were engraved in his factory in five years. In 1883, Wolff handed over the entire company to the Society of Industry and Commerce in St. Petersburg, which he founded. It operated until 1917, until the revolution.
