Senators of the Second Polish Republic (1935\u20131938)

Prince Janusz Franciszek Radziwiłł (3 September 1880 – 4 October 1967) was a Polish nobleman and politician.

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.

Artur Śliwiński (Polish: [ˈartur ɕliˈviɲskʲi]; 17 August 1877 – 16 January 1953) is the 8th Prime Minister of Poland from 28 June – 7 July 1922. In 1915 he had presided over the National Central Committee, which sought Polish independence from partitioning powers.
