Other Austrian and cryo-related memories

There are photos below, if the words are too much!


All scientists want to have their work published, and then cited i.e. referred to by other scientists because this validates their efforts. My goal was visually improved cellular ultrastructure.   I was surprised to find my work discussed in a mathematical modelling book that was published in 1987 .....

Quotes from the book .....
"Prior to the experimental work of Ryan et al. (1986), many people, including the author, assumed that propane was the most efficient coolant when plungong metal sample holders or thermocouples.  This erroneous conclusion was based on the assumptions that the degree of subcooling governs the cooling efficiency when metal sample holders are used and that propane has potentially the highest available subcooling of all the cryogenic fluids (see Table 5.1). Ryan's experiments, however, show that the vapour film surrounding his 300
mm thermocouple was sufficiently thin to allow forced convection effects to override the advantages of a high degree of subcooling." (page 114),

also .....

"As far as the author is aware, the only only continuous plunging experiments using metal samples (thermocouples) quenched into different coolants carried out to date are those of Ryan et al. (1987).  Ryan used a 300 mm diameter Cu/Co thermocoupleassembled so that the geometrical arrangement was equivalent to a cylindrical sample plunged with its axis perpendicular to the plunge direction.  By applying equation (2.42) tp Ryan's measured cooling rates, the author has been able to derive the following empirical expressions for the average surface heat transfer coefficient in the temperature range 273-173 K"
..... the book then continues into equations and mathematical modelling.  (page 116).




The author, Bill Bald, became a collaborator on a later paper, published in 1990, where I measured ice crystal size experimentally and he modelled i.e. predicted it.  At high velocity plunging (6.7 m/sec) into ethans, I had a measured average ice crystal diameter of 54 nm and he predicted 52 nm.  Considering that one nanometre is a one millionth part of a millimetre, I was impressed.  We had a very successful publication.

Meeting Konrad Lorenz, joint Nobel Prize winner for Physiology & Medicine in 1973 with Nikolaas Tinbergen and Karl von Fritsch after deciphering the meaning of the bee "waggle" dance. He and I spoke about Amphioxus.  This was during a family holiday to Austria, in 1988 (by our next holiday there, in 1990, he had died, aged 85). We were visiting the Konrad Lorenz Research Station at Grunau (part of the Konrad Lorenz Research Institute). The visit arranged by Prof. Hans Adam (Uni. Salzburg) and the Station Director, Kurt Kotrschal, both friends and visitors to the Marine Biological Association, Plymouth.  Konrad was in failing health and using a wheelchair. During this visit we were told of studies on grey lag goose behaviour and our daughter remembered the "goose girl" for a long time after.  Photo: Karin Bernatzky, our good friend and Photographer, Zoology Institute, Uni. Salzburg.

Sept. 1988, dancing with Dr. Bernadette Griffond, Lab. de Zoologie et Embryologie, Besançon, France, at the 14th Conference of European Society of Comparative Endocrinology, University of Salzburg where I showed two scientific posters and had the adminibistrative job of taping and transcribing the lecture of Dr. Berta Scharrer on the occasion of her being awarded an Honorary Doctorate by the University of Salburg.  This was an occasion when the proceedings were interspersed with playing from a string quartet, playing Mozrt, of course.  This was a plane trip.

Pat Echlin's signing in my copy of the book - cryo-freak ..... that is an honour, indeed!


When I was a Professor, in 1993!
Albeit a Guest Professor ..... engaged for 5 lectures and 5 practical sessions .....


The contract - for 11 days!


1994, June - talk at Seefeld, drive to Zurich (stay with Dr Paul Walther), drive to Salzburg (University plus the Austrian Academy of Sciences Institute of Molecular Biology), then to Jena (formerly East Germany). This photo was taken somewhere in the garden of Walter Richter.  It was while here that we heard the eerie cry of a wolf!  I was told it was not unknown: it was certainly different.  At some point, after my presentation at the Institute for Ultrastructure Research, I was taken for a meal in a windmill, now surrounded by forest, at a table used by Napoleon before/after the Battle of Jena. From left: Dr. Walter Richter, Dr. Konrad Semmler, Prof. Helmut Meyer and KR.  Prof. Meyer thanked me in front of the students and staff for sending reprints of my work during the former GDR days, before the reunification of Germany.  The trip was arranged largely by Johannes Wunderlich, missing from this photograph, whom  I met in Seefeld.

The house is an old farmhouse and they are permitted to retain old stills!


With Frau Anni and Prof. Hans Adam, very old friends that I met in the lab. in Plymouth.  Hans is another person who influenced my life
with his frequent invitations to the University of Salzburg and the Guest Professorship in 1993.

From 1981, a paper encouraged by Prof. Hans Adam while visiting the laboratory in Plymouth, in 1980.
"Onkle Hans" was the Editor of "Mikroskopie", the German language microscopy journal based in Vienna, Austria, .
This was the first of my 25 first author publications, out of a total of 66 incl. with other scientists.


Familie Bernatzky in 2015 - we have known each other since my first visit to Salzburg in Sept/Oct. 1986 ..... 30 years .....
Günther and Karin stayed with us twice in Plymouth, before they had children.

Where did the time go?

Altogether, including trips to Strasbourg (France), Eindhoeven (The Netherlands), Zürich (Switzerland), Brussels (Belgium) and Bochum, Leipzig and Ebern (these three in Germany for target shooting), there were 27 trips by car and plane to these countries.
