ULRICH GRIGULLON HIS 70~~ BIRTHDAYU LKICH GRKULL, renowned
bothin Germanyandin
the heat transfer society world-wide,celebrates his
70th birthday on 12 March 1982.
Born in Gallingen, a Small East Prussian town, hemoved to many places in an ever-changing
world:
school days in KGnigsberg(Kaliningrad),studiedmechanicalengineering
at the Technical University
Danzig (Gdansk), assistant to Ernst Schmidt in both
Danzig and Braunschweig(where he received his
doctor of engineering degree), engineer and officer on
mine-sweepers and submarines in the Atlantic and theNorth Sea, advisor to a chemical and a textile firm,
director of an insulation firm, work with Farbenfabriken Bayer and finally professor and holder of thechair of thermodynamics
at the Technische
Hochschule Miinchen.
Seventy years of outside turmoil filled with world
wars, post-war economic
breakdownand a Wirtschaftswunderrecovery, a period filled with political
tit4,25:3

Aand sociological changes did not alter Ulrich Grigull
from being both dispassionate and calm. With a “lente,lente” he clears a tense situation, he relies on the“normative Kraft des Faktischen”(normativepower offacts) and solves many a problem with his sense ofhumour.
Ulrich Grigull is now seventy; to those of us who
know him from his many activities this seems unbelievable: he is as active as always, if not more so thanbefore.
As a “spiritus rector” he has been active in thenational and international
heat transfer community
for more than two decades, in a time when world-widebonds were tied in heat transfer. From its instigation
he has been an editor of the International
Journal ofHeat and Mass Transfer. As the idea of international
heat transfer spread from this journal’s editorial group,
he became a founding member of the Assembly forInternational
Heat Transfer
Conferences.

creation of the International Centre ofHeat and Mass
Transfer in Belgrade. Ulrich Grigull was once again
among the founders. As a member, a president or vicepresident of these groups and many others he proved askillful skipper around the many hazards which occur
in international cooperation.
Many scientists in the world know him as their hostat his Munich Institute: they will certainly remember
discussions with him, profound and direct; and they
will remember the joyful parties there too.
Ulrich Grigull has contributed to almost every
aspect of heat transfer or even laid fundamentals with
about 120 articles and about 40 books and bookcontributions. More than 40 scientists call him their“doctoral father” and many, many students learned ofthermodynamics and heat transfer from him.
He was honoured with the Bavarian Order forMerits, the Golden VDI Pin, the GauRMedal, theArnold Eucken Medal, the Max Jakob Award; he wasappointed member of the Bavarian Academy of Sciences, and a member of the Scientific Council of theGerman Federal Government, to name only a few ofthe many positions actively held and filled by him.
Last but not least, he is a father and grandfather to alovely family. Those who have met Lydia Grigull, hiswife, will never forget her charming and overwhelming
hospitality.
The international heat transfer community bids a
happy birthday and wishes its beloved and respectedmember, Professor Dr.-Ing. Ulrich Grigull, health andhappiness to him and his family.
