Eugene Dietzgen

[1] Dietzgen, heavily influenced by his father, one of Karl Marx's favorite philosophers, provided his factory workers with many amenities not often found in the 19th century.

These included separate bathrooms for men and women, open windowsills with flowers decorating the air, and a general atmosphere of a healthy working community.

[1] The company still exists, and its second building remains as a part of DePaul University, at the corner of Fullerton Avenue and Sheffield, in Chicago's once heavily German neighborhood of Lincoln Park.

[1] The company was noted for its production of slide rules, which Dietzgen started in 1898 after acquiring a patent from John Givan Davis Mack (1867–1924).

[4] Dietzgen actively promoted the work of his father, Joseph, and added additional philosophical material of his own.
