The achievements of Polish scientists are presented against the background of rapid development of photochemistry in the years 1900 - 1918. In organic photochemistry the photohalogenations were the topic of the main interest to many chemists at the universities of Lvov (Bronisław Radziszewski, Stanisław Opolski, Stanisław Tołłoczko) and Cracow (Julian Schramm's folowers). He acenaphthylene photodimerization was discovered in Cracow by Karol Dziewoński in 1912 and the structure of two stereoisomers of the dimer thus obtained was proposed (1913). Contributions of Jan Bielecki, done in Paris (1910-1914), in collaboration with Victor Henri and René Wurmser, are mentioned. Extensive photokinetic studies carried out by Ludwik Bruner at the Jagiellonian University (1907-1913) and the precursory work of Józef Wierusz Kowalski on the phosphorescence spectra of organic molecules, performed in Fribourg (1907-1914), are discussed.
