Dr. Heinrich Wilhelm Gudenau: In memoriam
On August 8, 2019, Heinrich Wilhelm Gudenau passed away.
Prof. Gudenau was born in Wanne-Eickel, Germany,1936. He graduated in 1967 from
RWTH Aachen University in the field of Iron and Steel Metallurgy and then earned his
Ph.D. (Dr.-Ing.) in 1967 and Habilitation in Tech. in 1972, as well as Dipl.-Eng. in
Economy Science in 1971. In 1971, he took the position of a Senior Engineer at the
Inst. of Iron and Steel (IEHK) in RWTH Aachen University.
In 1972, Prof. Gudenau went to Japan as one of the first European researchers. He
worked both at Tokyo Institute of Technology and at the steel company, Nippon Kokan
(NKK, Currently JFE Steel). Later he worked as visiting Professor and consultant in
Australia, Brazil, Canada, China, Egypt, Finland, India, Japan, Korea, Sweden and
In 1982, he became full professor at RWTH Aachen University in teaching and research
in the field of Iron and Steel Metallurgy, and fulfilled this responsible task for 20 years. In
2001, he retired from RWTH Aachen University as full professor, but continued his
activities on teaching in this University and research supervising in many companies.
He was an Honorary Professor at the University of Science and Technology, Beijing, the
University of Technology, Shenyang, China and the State University of Mining,
Dnepropetrovsk, Ukraine, and was a Fellow of various metallurgical associations. He
was particularly proud to receive the title "Honorary Member of the Iron and Steel
Institute of Japan" in 2005. Due to Prof. Gudenau’s extensive contribution to the science
community, FLOGEN dedicated the 2015 SIPS conference to his name, The Gudenau
International Symposium on Sustainable Iron and Steel Making, which took place
in Antalya, Turkey. There, FLOGEN had the honour to award Prof. Gudenau the Fray
International Sustainability Award for his outstanding work in his field of research.
His research activities covered firstly on ironmaking such as iron ore agglomeration,
coke making, blast furnace, and new ironmaking technologies without blast furnace;
direct reduction process, reduction and melting of carbon composite iron ore
agglomerates in rotary hearth furnace ---- he started these studies earlier as a pioneer
and yielded state-of-the-art technologies, which were applied in various commercial
plants. In addition, he aimed at the importance of energy and environmental problems
and contributed research developments applicable to industries, such as gasification
technology of coal and elimination of harmful materials produced in steel plants.
Professor Gudenau was highly evaluated by everyone as wide and faraway viewer, a
man of good judgment and high sense of humor, having a deep passion for training
Prof. "Heiwi" Gudenau was the author or co-author of hundreds of scientific publications
and the supervisor and co-supervisor of more than 300 doctoral theses, mostly in the
field of ironmaking and sustainable development in the steel production of the world.
On behalf of Heiwi's pupils in Japan, we give our deepest sympathy and condolences to
Prof. Tatsuro Ariyama, worked at NKK, JFE Steel and Tohoku University
and Prof. Tateo Usui, Emeritus Professor, Osaka University and Visiting
Professor, Federal University of Ouro Preto, Brazil
