This article is the first part of research devoted to the inception and formation of mathematics history as a separate science in Russia. Its elements began intensively emerging in the epoch of Peter the Great and underwent several developmental stages. This work outlines five stages that Russian scientists went through while molding elements of studies in the history of mathematics into a science...

Poland in the years 1918–1939 became one of the main centres of mathematical logic in the entire Word. This paper describes the rise of this field in Poland, Polish logical circles, organizations, journals and the main achievements of Polish logicians.

The Samuel Dickstein's price is awarded for outstanding achievements in the field of mathematical education, popularization and history of mathematics.

In this note, results of the Conference ”Poděbrady 2018” are discussed.

This article is devoted to the Seminar on Applied Mathematics, conducted in 1948-1960 by Professor Hugo Steinhaus in Wroclaw. It is based on the protocols of this Seminar so far not discussed anywhere. Many facts related to Professor Hugo Steinhaus can be found easily in the literature, also in the diary of the professor \emph{Mathematician for all seasons--recollections and notes.} (2016). Steinhaus...

We present a subsequent volume, 12 (2018), of the Series VI of Roczniki Polskiego Towarzystwa Matematycznego – “Antiquitates Mathematicae”, a journal devoted to history of mathematics. In it, we offer 10 articles (6 in English, 4 in Polish), a profile of Professor Lech Maligranda-the recipient of the Samuel Dickstein Main Prize of the Polish Mathematical Society for the year 2016, as well as a report...

An analysis of the mathematical contributions of Juliusz Schauder through the writings of contemporary mathematicians, and in particular Leray, Hadamard, Banach, Randolph, Federer, Lorentz, Ladyzhenskaya, Ural'tseva, Orlicz, G\aa rding and Pietsch.

Tomasz Franciszek Schreiber, a young Polish mathematician, passed away on December 1, 2010. Since 2009 he was a professor at the Department of Probability Theory and Stochastic Analysis at the Faculty of Mathematics and Computer Science at the Nicolaus Copernicus University (NCU) in Toruń.

Jan Ptaszycki was a Polish mathematician working in St. Petersburg in the period 1876--1912. In Poland, he is forgotten, and in Russia considered generally for Russian mathematician, known there as Ivan Lvovich Ptaszycki. There is no article about it on Polish {\it Wikipedia}, while there are three articles in Russian. In historical-mathematical Russian literature, depending on the author, it is reported...

The paper describes results of Polish mathematicians of XX century concerning the Baire classification of functions and Borel classification of sets. As usual, numerous theorems came from Wacław Sierpiński, remaining are due to Kazimierz Kuratowski, Stefan Banach, Stefan Kempisty, Edward Szpilrajn (Marczewski), Andrzej Alexiewicz, Władysław Orlicz, Adolf Lindenbaum, Roman Sikorski, Ryszard Engelking,...
