This book was compiled by their former students and co-workers to express the
deep gratitude and fond memories about these two professors. The chapters in this
book contain the examples of research created under either their direct supervision
or initiated by them by offering new ideas.
Professor Henryk Hawrylak, born in 1925, came to Wroc?aw in 1945, just
after the end of the Second World War and started studying at the Department of
Mechanical and Electrical Engineering of the Wroc?aw University of Science and
Technology. During his student years, he was very active, serving the academic
community in the student organizations “Academic Guard” and “Brotherhood for
Help”, both of them helping the university community to cope with difficulties of
everyday life in post-war Wroc?aw.
He obtained his Ph.D. degree in 1961 and his D.Sc. degree in 1965. His D.Sc.
dissertation on “The theoretical basis of design and selection of the working system
of bucket wheel excavators” catalyzed new avenues for research and development
of the entire branch of the heavy machine design and established the scientific
school which Prof. Hawrylak created and managed for the subsequent 25 years. He
was nominated the Associate Professor in 1969 and the Full Professor in 1975.
