Professor Mikołaj Łabowski was born on the 17th of December, 1935, in Florynka in the southern part of Poland. He graduated from the Faculty of Mathematics, Physics and Chemistry of the Adam Mickiewicz University receiving his Master of Science degree in physics in 1962. Eight years later he obtained his PhD title from the same university. In 1981, on the basis of the book “Ultra- and hypersonic properties of selected liquids and critical mixtures” he obtained the degree of habilitated doctor. The President of Poland awarded him the titles of Associate Professor in Physics in the year 1991 and Full Professor in 1999. From 1985 to 1987,Mikołaj Łabowski held the post of Vice-Dean for Students’ Affairs at the Faculty of Mathematics and Physics of the AdamMickiewicz University. In the years 1996–1999, he was the Director of the University’s Institute of Acoustics. He held many posts in the Polish Acoustical Society, of which he was a HonoraryMember. He always served with advice and assistance in scientific matters to the Committee of Acoustics of the Polish Academy of Sciences. Professor Łabowski was an outstanding scientist, one of the founders of ultrasonic physics in Poland. After returning from scholarship in the Lomonsov University in Moscow, he became an expert in the field of ultrasonic studies of liquids and liquid mixtures. His groundbreaking works on ultrasonic properties of critical binary mixtures opened up new perspectives in the research of dynamic phenomena in the vicinity of critical temperatures. Professor Łabowski’s outstanding scientific achievements were recognized by rewarding him the Minister of Education Prize in the years 1981 and 1987. Throughout his whole professional career associated with the Adam Mickiewicz University in Poznań, Professor Łabowski has published over 100 papers, mostly in renowned international scientific journals, and carried out an intensive teaching activity. Through his profound knowledge and enthusiasm, Professor Mikołaj Łabowski continuously inspired colleagues and collaborators and decisively shaped the development of ultrasonic physics in Poznań. With the death of Professor Mikołaj Łabowski, Polish acoustics has lost a great researcher, teacher, and scholar.}, type={Commentary / Komentarz}, title={In Memoriam: Professor Mikołaj Łabowski}, URL={http://www.czasopisma.pan.pl/Content/101564/PDF/17_paper.pdf}, doi={10.2478/aoa-2013-0069}, }
