**Ryszard Engelking** (born 1935 in Sosnowiec) is a Polish mathematician. He was working mainly on general topology^{[1]} and dimension theory. He is author of several influential monographs in this field. The 1989 edition of his *General Topology* is nowadays a standard reference for topology.^{[2]}

## Scientific work

Apart from his books, Ryszard Engelking is known, among other things, for a generalization to an arbitrary topological space of the "Alexandroff double circle",^{[3]}^{[4]} for works on completely metrizable spaces, suborderable spaces and generalized ordered spaces.^{[5]} The *Engelking–Karlowicz theorem*, proved together with Monica Karlowicz, is a statement about the existence of a family of functions from to with topological^{[6]} and set-theoretical^{[7]} applications.

In addition to research papers authored just by himself, he also published jointly with Kazimierz Kuratowski, Roman Sikorski, Aleksander Pełczyński and others. He has published about 60 scientific works reviewed by MathSciNet and Zentralblatt.

## Translation works

Apart from mathematics he is also interested in literature. He translated into Polish French authors: Flaubert's *Madame Bovary*, and works of Baudelaire, Gérard de Nerval, Auguste de Villiers de L'Isle-Adam, Nicolas Restif de la Bretonne. For these activities he was awarded by Literatura na Świecie (*World Literature*).
