Richard B. Hetnarski (May 31, 1928 – June 8, 2024) was a Polish-born American academic and translator who was a professor in the department of mechanical engineering at Rochester Institute of Technology. He was an ASME Fellow since 1983[https://www.asme.org/getmedia/9faec63b-9349-4b3f-ad9f-3c8edf856c2e/fellows-all-updated-2020_7.pdf#page=29 ASME] 2020 Fellows List, p. 29 and a New York State Licensed Professional Engineer since 1976.NYS Professional Engineer License. 12 Mar [https://drive.google.com/uc?export=view&id=1jJOwT1SLEffyAPRHHPP_omVBNK4LTa0t 1976] He is best known for his contributions{{Cite web|title=Richard B.

Early life and work

Richard B. Hetnarski was born in Stopnica,Stopnica, Main Square (rynek) at the end of the market day ca. 1936 Poland. He received a Master of Science degree in mechanical engineering at Gdańsk University of Technology in Poland in 1952; an M.S. degree in mathematics at the University of Warsaw in 1960; and a Doctor of Technical Sciences degree at the Institute of Fundamental Technological Research of the Polish Academy of Sciences in Warsaw in 1964, mostly under the tutelage of Professor Witold Nowacki.Professor Witold Nowacki Assessment. 11 June [https://drive.google.com/uc?export=view&id=1m9nW5JmEyZeOKNla8rJ4QXgcHvxvaYve 1969]"Assessment of Dr. Ryszard B.

Polish Academy of Science. 14 June, [https://drive.google.com/uc?export=view&id=1UV1K6J6HD-ujeEdxjLYOmfsfuVaJeKwt 1969] In his career he concentrated his research on Solid Body Mechanics.

In Poland, he worked at the Institute of Aviation in Warsaw (1955–1959), and also at the Institute of Fundamental Technological Research of the Polish Academy of Sciences (1959–1969). In the years 1964–1965, he held post-doctorate fellowships at Columbia University in New York and at Northwestern University in Evanston, Illinois.

Immigration to the United States

In 1969, he and his family emigrated from Poland to the United States, and he became Visiting Associate Professor in the Department of Theoretical and Applied Mechanics at Cornell University in Ithaca, New York, for the year 1969–1970. He became a United States naturalized citizen in 1974.

Personal life

He was known for his deeply pro-democracy convictions. In 1989, when the Communist government in Poland was collapsing, he gave a number of presentations on the subject at three TV network affiliates of NBC, ABC, and CBS. When Lech Wałęsa, Nobel Peace Prize winner and former president of Poland, visited Rochester Institute of Technology"RIT's latest in-the-news stories".

He was the founder (with Naotake Noda) and president until 2020 of the International Congresses on Thermal Stresses (ICTS). These Congresses are held every two years consecutively on three continents, that is, in Asia, America, Europe. The first meeting was held June 5–7, 1995 in Hamamatsu, Japan at Shizuoka UniversityFirst International Symposium on Thermal Stresses and Related [http://www.gbv.de/dms/tib-ub-hannover/190313498.pdf Topics] and second was held June 8–11, 1997 in Rochester, New York, U.S. at Rochester Institute of Technology.Second International Symposium on Thermal Stresses and Related [http://facta.junis.ni.ac.rs/macar/macar97/macar97-23.pdf Topics] These were titled First and Second International Symposium on Thermal Stresses and Related Topics, respectively.
