**The Great Departed**

Professor Jan Kubarski (1950–2013)

A long-time employee of the Institute of Mathematics of the Technical University of Łódź, professor of mathematical sciences, a renowned specialist in the field of differential geometry, respected scientist and university teacher, a former Vice-Dean of the Faculty, awardee of the Silver Cross of Merit.

### Professor Włodzimierz Krysicki (1905–2001)

Born on the 1st of January 1905 in Warsaw. A senior Polish mathematician, Professor and Honorary Doctor of the Technical University of Łódź. He was a teacher of several generations of Polish mathematicians and the author of several academic books, including "Problems in Mathematical Analysis" which has had 29 editions and was translated into English and German. He wrote numerous books popularizing mathematics, such as "Secrets of numbers", "How did we count in the past and how do we count today?", "Xs and Ys". He died on the 19th of September 2001 in Łódź.

### Professor Tadeusz Świątkowski (1933–1994)

Tadeusz Świątkowski was born on 28th of November 1933 in Bełchatów. In 1951 he enrolled as a student of mathematics at the University of Łódź and graduated there in 1955. Already a year before he started working as an assistant (junior lecturer) at the Technical University of Łódź. In the period 1959 - 1962 he worked at the University of Łódź before returning to the Technical University of Łódź. In 1960 he was awarded a PhD in mathematics, DSc (habilitation) in 1966 and the State title of Professor in 1978. During his scientific career, between 1959 and 1994, Professor Świątkowski published more than 30 research papers. One of the greatest results of Professor Świątkowski was the monotonicity theorem, contained in his habilitation dissertation. However, his scientific achievements cannot be measured by publications alone. Many of his ideas were shared with his students and are scattered in their works; only they know how much they owe to his ingenuity, humility and kindness. Professor Świątkowski successfully supervised 40 PhDs in mathematics. He was the Director of the Institute of Mathematics of Technical University of Łódź and received many state awards. He died prematurely on 30th of October 1994 in Lodz.

### Professor Lucjan Siewierski (1915–2004)

He was born on the 2nd of August 1915 in Chicago, USA. In 1922 he arrived with his family in Poland and settled in Łódź. In 1938 he completes the studies at the Faculty of Mathematics and Natural Sciences of the University of Warsaw but receives the degree of Master of Philosophy in Mathematics only in 1946 (the eight years? delay was caused by the military service and the war). In 1945 he took a job as a teacher in the Municipal Secondary School in Lodz (now the High School No 3 named after T. Kościuszko). From 1949 he worked at the Technical University of Łódź, moving up the academic ranks. He received PhD in 1958 and DSc (habilitation) in 1961, both from the Faculty Board of Mathematics, Physics and Chemistry of the University of Łódź. The State title of Professor was conferred upon him by the Council of State in 1969. Prof. A. Bielecki from the Maria Skłodowska-Curie University in Lublin, in the assessment of the professorial application of Professor Siewierski wrote: "Docent Lucjan Siewierski in his habilitation dissertation obtained a result considered to be the best achievement of the Łódź School of Analytical Functions" (solution of the conjecture of Charzyński and Tamm about the coefficients of bounded univalent functions which are close to identity). Professor Lucjan Siewierski was a friend of the youth . His pupils and students always referred to him as "our professor Lucek". Professor Siewierski is the author of 10 scientific articles, a co-author of six books and scripts. He supervised two PhD students and was an external examiner of eight doctoral theses. He received many state awards. For many years he served as a Deputy Director (Research) of the Institute of Mathematics.
