GRIGULL,
Professor emeritus, TechnischeUniversitat, Milnchen, celebrates his 80th birthday on
12 March 1992.
He is one of the founding members of the International Jownal of Heat and Mass Transfer. Together
with other scientists of various countries he felt theneed for a journal that could bring together the many
papers which were published in all of the many
journals in different fields. It soon became apparent
that such a journal could not only bring together
papers but also people ; people from different countries from East and West, worldwide. Heat Transfer
proved to be a field with worldwide activities, anautonomous field, unalterable for the many problems
to be solved. Grigull advocated strongly that this‘Inte~ational
Heat Transfer’ manifests itself in a
regular conference and in 1966 the ‘International
Assembly for Heat Transfer Conferences’ wasfounded. Ever since, this assembly has taken care of aHeat Transfer Conference every four years, attracting
up to one thousand scientists and their comp~ions.
Despite political turmoil and ideological barriers,
these Heat Transfer Conferences have opened doors
and always gathered scientists, many of them becoming personal friends.
In the national scene, Grigull has been equallyactive in having Heat Transfer recognized as a selfULRICH

bertr~gung.

Ulrich Grigull has been and still is one of the outstanding promoters of Heat Transfer in his own country and throughout the world. His scientific activities
span the entire field of Heat Transfer.
As a young assistant to Ernst Schmidt he investigated the Heat Transfer in the thermodynamic critical region. In this region, thermodynamic properties
are so advantageous for Heat Transfer that even natural convection becomes an effective regime for coolinghigh-temperature equipment. This cooling method
was applied to gas turbine blades in 1942 and it isreported that ‘it was amazing to look at the turbine
case, glowing white, and hearing the blades runningsmoothly’. His doctoral thesis on ‘Heat Transfer in
Turbulent Film Condensation’ has become one of theclassics in the field.
During the Second World War, Grigull had to servewith the Kriegsmarine as an engineer and officer. In
the following years he worked in several firms ofchemical and textile branches and became director of
an insulating firm. Besides his industrial work he wasable to complete the revised and heavily extended new
edition of the book Grun&esetze der Wiirme593

This book was translated into English,Japanese, Russian and Spanish; it represents one of
the most extensive and thorough standard works onHeat Transfer in the German language. Now, for theimmensely increased knowledge in the field, Grigull
decided on a Book Series on Heat and Mass Transfer.
The following volumes have appeared:
Heut Conduction (with H. Sandner),
Mass Transfer (by A.
Mersmann),
Convective Heat Transfer (by G. P.
Merker), Condensation and Boiling (by K. Stephan),Thermophysical Properties (by W. Blanke, Editor),
Radiation Heat Transfer (by R. Siegel, J. R. Howelland J. Lohrengel) and Optical Measuremenfs (by W.
Hauf, U. Grigull and F. Mayinger).
In 1960 U. Grigull accepted the Lehrstuhl fur Technische Thermodynamik(Chair for Technical Thermodynamics) at the Technische
Hochschule
Miinchenas the successor to Ernst Schmidt. Professor Grigull
secured the tradition of this chair and added to its highscientific standing. Optical methods using shadowgraph and Schlieren methods as well as interferometrywsith a Mach-Zehnderinterferometer
were furtherdeveloped. Thus, Heat and Mass Transfer phenomena
were made visible and better understood.
As a University Professor Ulrich Grigull has contributed to almost every aspect of Heat Transfer andhe laid foundations
with about 120 scientific papers
and more than 40 books or book contributions.
Morethan 40 scientists call him their ‘Doctor father’ and agreat many students learned the basics of Thcrmodynamics and Heat Transfer from him.
U. Grigull is, certainly, one of the best known members of the International
Heat Transfer Society, has
held numerous positions, and had numerous honours
bestowed on him.
The International Journal of’ Heat und Mass Trunsjer
wishes to honour its Co-Founderand Editor. Prof.
