Professor Yoshiro Katto
on his 65th birthday

Yoshiro Katto, who was born on 3 September 1924 in Nara city, Japan, celebrates his 65thbirthday this month. We wish on this occasion toapplaud his contributions to the field of heat transfer
and express our felicitations.
Professor Katto attended the University of Tokyo,
where he received his B.S. degree in mechanical engineering in 1946. After graduation, he worked first at
the Institute of Science and Technology of the University of Tokyo and then moved to the National
Aerospace Laboratory. In 1960, he received hisD.Eng. degree for a thesis entitled “Some Fundamental Natures of Resonant Surge” from the University of Tokyo, and in 1963, joined the Universityof Tokyo as a professor of mechanical engineering.
After about 23 years of academic life he retired fromthe University of Tokyo in 1985 and was appointed
as professor emeritus. Since 1985, he has been continuing his scientific activities at Nihon University asa professor.
From 1946 to 1961, he studied various important
problems in the wide field of thermal en~nee~ng,mechanical vibrations and lubrications. The famous
pioneering paper entitled “Theoretical Contributions
to the Study of Gas-lubricated Journal Bearings”,
which was co-authored with Prof. S. Soda and published in 196 1 in Journal of Basic Engineering, ASME,
is one of his early notable works. For this work hereceived one of the best paper awards in 1963 by theJSME.
PROFESSOR

In 1962, he started his research on heat transfer at
the University of Tokyo. His work involved boiling,
thermal radiation, natural convection in porous
media, critical two-phase flow and thermal oscillations of a gas-column in a tube. He has especiallybeen absorbed in the analysis of critical heat flux inpool as well as forced convection boiling, and has
published a number of papers on critical heat flux. Hehas thus succeeded in deriving the general correlationof the critical heat flux known as Katto’s correlation.
For these outstanding
cont~butions,he againreceived the JSME best paper award in 1979, and won
a prize at the ASME-JSME Thermal Engineering
Joint Conference in 1983.
Professor Katto has authored or co-authored about
150 journal and conference papers in the area of heattransfer and other fields of engineering. He has written
three books on heat conduction, thermodynamics andheat transfer. Among them is the heat transfer textbook L)ePmetsu G&on (in Japanese) which has beena best-seller as a guiding book on heat transfer forJapanese researchers, engineers and students. His educational contribution to the development of Japaneseheat transfer research should not go unnoticed. He
has also contributed review articles or chapters to
many handbooks and books on heat transfer.
Professor Katto has been a very active member of
the JSME and other Japanese scientific societies. He
successfully filled the important posts of president ofthe JSME and president of the Heat Transfer Society

of Japan, and for many years, he was a director of theJapan Society for Aeronautical and Space Sciences aswell as the Gas Turbine Society of Japan. Since 1987,
he has been a member of the Engineering Academyof Japan. He has also played an important role inpromoting Japanese research in science and engineering from the national point of view as a memberof government committees. Additionally, he has contributed to the international heat transfer community
as an editor or a member of the editorial board ofseveral international
journals including the International Journal of Heat and Mass Transfer and theJournal of Multiphase Flow and as a representative or a
general secretary of several international conferences.
He is now the delegate from Japan to the Assembly forInternational
Heat Transfer Conference. For theseeminent contributions to the field of science and technology, he won a commendation as a distinguishedscientist by Tokyo Metropoly in 1983.
Professor Katto’s work reflects his philosophy oflife and is based on his deep and wide knowledge ofnatural and cultural sciences. He is a person of truly

gentle and kind character, and is known as an outstanding educator. He has supervised about 60 doctoral or master’s theses, and over 120 students have
graduated from his laboratory. Each of his graduates
plays an active part in Japanese academic circles orindustry.
Professor Katto is a devoted husband, father andgrandfather. He is blessed in his good family. His wife,
Sachiko, is a polite and cheerful lady, and everyone
who meets her is impressed by her hearty warmth.
Recently, improving their spare time, Professor andMrs Katto enjoy hiking on the hills or the mountains
in the suburbs of Tokyo and coming in contact withnatural beauties.
On behalf of Professor Katto’s students, his colleagues and friends all over the world, we would like towish him many happy returns and continued success.
