Roman Franciszek Henryk Nitsch was born on September 5, 1873 in Podchybie. In 1899, he graduated from the Faculty of Medicine of the Jagiellonian University. Until 1915, he worked as an assistant in the Department of Hygiene of the Jagiellonian University in Krakow, cooperating with Prof. Odon Bujwid. In 1915 he was nominated as an associate professor of hygiene and bacteriology. In 1920, he was appointed full professor of bacteriology at the University of Warsaw. For the rest of his life, he was associated with the research center in Warsaw. He died on 29 March 1943. Roman Nitsch’s scientific activity, which mainly involved his research on vaccination against rabies, is a significant contribution to the development of Polish medical microbiology. The analysis of Roman Nitsch’s scientific achievements proves that he was a continuator of Ludwik Pasteur’s and Odon Bujwid’s – his predecessor and teacher – research thought, as well as the author of pioneering works that shed new light on the world of microbes, which was then only gradually being discovered.

Edward Schunk and Leon Marchlewski were to play a decisive part in the history of research on chemistry of chlorophyll and its derivatives. During only a few-year stay of Marchlewski in the Schunck laboratories in Kersal outside Manchester, a groundbreaking invention in the history of biochemistry took place: the close chemical relationship on the level of chlorophyll derivatives and haemoglobin was revealed. Also then, despite a considerable age difference between them, Schunk, who was at the end of his scientific career and Marchlewski just at the start, they became close friends. On the basis of the collection of original Schunk’s letters to Marchlewski, written in the years 1889–1902, we tried to reconstruct the character of their relationship in science, confronting topics raised in the letters with works published at the time. We sought to establish whether Schunk could have been inspired by research of his Polish colleague and, in turn, if remarks and suggestions of the Englishman could have influenced Marchlewski’s research programme. For better understanding the field of research of both scientists, we also shortly described the state of knowledge on chlorophylls and their derivatives at the turn of the 19th and 20th centuries.
