Wysłouch was born in Polesia, in Socha, a village in the Grodno Governorate of the Russian Empire (present-day Belarus).

From 1881 he was affiliated with Lud Polski, a left-wing newspaper run by Bolesław Limanowski (as a result of which he was imprisoned in the Warsaw Citadel for three years).

In 1885 Wysłouch moved to Lviv, where together with his wife Maria he ran a monthly newspaper, Przegląd Społeczny until it was stopped by the Austrian officials in 1887.

He became a member of the party's Head Council, but in 1912 he left in order to establish a new entity called "PSL Union of the independent popular activists".

After her death in 1905 he married Bronisława Wysłouchowa, which later became a colonel in the Polish Armed Forces in the West as well as an inspector of the Women's Auxiliary Service.
