Professor Tadeusz Wilgat was born on the 16th February, 1917 in Jekaterinoslav in the Ukraine. He received primary and secondary education in Lublin. He began his studies at the University of Warsaw, and then moved to the Jagiellonian University. When World War II broke out in 1939, he settled in Lublin, where he began work as a geography teacher and participated in secret tuition. Since 1945, his work as a scientist and an educator has been associated with the University of Maria Curie-Skłodowska. He is the author of over 200 scientific papers, 28 of which deal with the research on the lakes and area of the Łęczna-Włodawa Lake District. At the end of 1940s and the beginning of 1950s, he began a comprehensive study of the lakes in the Lublin Polesie. The findings of the study were presented in the "Catalogue of Polish Lakes", published in 1952. This year, thanks to Professor Wilgat's initiative and scientific work, a half-century anniversary of the first complex study of the Łęczna-Włodawa Lake District occurs. A full compilation of the materials was presented by the Professor in a monographic work "The Łęczna-Wlodawa Lakes" in 1954. The work will always remain a basis for limnological studies of this area.
During the successive years, Professor Wilgat headed team investigations which resulted in publications on the Łęczna-Włodawa Lake District, including: "The Lublin Polesie", "Influence of mining on water conditions in the Lublin Coal-Basin", "Shallow groundwaters in the area affected by the central region of the Lublin Coal-Basin", "The Łęczna-Włodawa Lakes". The character of these works is clearly dominated by the issues of hydrosphere protection. The scientific work of Professor Wilgat has been inextricably linked with his social activity, which has led to the creation of the Polesie National Park, as well as landscape parks and protected landscape areas.
The present volume contains several papers by Authors from neighbouring countries: Lithuania, Byelorussia and Ukraine. The studies deal with the lake districts of those countries, which are integrally connected with the Polish ones. When delivering the second issue of "Limnological Review" to our Readers, we hope the periodical will become a forum for the presentation of scientific achievement and for discussion and exchange of thought between limnologists from Central and Eastern Europe.
