The daughter of Bolesław Morzycki and Władysława Zakrzewska and the sister of Jerzy, she was also a polyglot who spoke seven languages: Polish, French, English, Persian, Finnish, German and Russian.
Aleksandra Piłsudska (née Szczerbińska; 12 December 1882 – 31 March 1963) was a Polish socialist and independence activist, member of Polish Socialist Party and Polish Military Organisation, the second wife of Józef Piłsudski.
Władysław Zygmunt Belina-Prażmowski (3 May 1888 in Ruszkowiec – 13 October 1938 in Venice), was a Polish cavalryman, colonel and politician.
He was a member of Związek Walki Czynnej since 1909, later Związek Strzelecki. Student of Lwów Politechnic in 1919–1913.
Serving under Józef Piłsudski, he became one of the first Polish soldiers - formally under Austrian command - who entered Russian-held Polish territory during the First World War. Member of Polish Legions, organizer and commander of 1st Regiment of Polish Uhlans and later 1st Brigade of Polish Uhlans. Later he fought in the Polish-Ukrainian War (1918–1919) and Polish-Soviet War (1919–1921). In April 1919 his troops were instrumental in taking Wilno. Piłsudski would declare Belina's cavalry action a most exquisite military action carried out by Polish cavalry in this war.
From 1929 he lived in Kraków and retired from the military. In 1931-1933 he was a mayor of Kraków and from 1933 to 1937, voivode of Lwów. In 1938 he retired from public work due to worsening health; he died later that year, aged fifty.
Wacław Kajetan Sieroszewski (24 August 1858 – 20 April 1945) was a Polish writer, Polish Socialist Party activist, and soldier in the World War I-era Polish Legions (decorated with the Virtuti Militari). For activities subversive of the Russian Empire, he had spent many years in Siberian exile.
Sieroszewski's Siberian experiences became the subjects of his many stories and novels—Na kresach lasów (At the Edge of the Woods, 1894), Dno nędzy (The Depths of Misery, 1900), Risztau (1899), Ucieczka (The Escape, 1904), Zamorski diabeł (The Overseas Devil, 1900). He also authored the popular Bajki (Fables, 1910). His 12 lat w kraju Jakutów (12 years in the Yakut country, 1900) provides the first extensive ethnographic account of the Yakut people.
Sieroszewski visited Korea (then the Korean Empire) in 1903. He arrived via boat to Busan, then traveled through the peninsula with an interpreter, speaking with locals on the way to the capital Seoul. He published a book on his experiences in the peninsula in 1905. The trip appeared to make an impression on him, and he would frequently mention Korea in later interviews. He once likened Korea's political situation, in which multiple foreign powers were encroaching on it, to Poland's.Whilst in Paris in 1910, he heard that Jan Wacław Machajski had been asking his friend Stefan Żeromski to provide a reference so that Machajski's wife would be employed by Kazimierz Dłuski. Having heard rumours circulated by the Polish Social Democratic Party of Galicia that Machajski was a terrorist, Sieroszewski wrote to Dłuski warning against getting involved with the Machajskis. When this letter fell into the hands of the police, they promptly arrested Machajski.
