also added to the interest of the Congress.
L. E. Preuss was Program Chairman for the
Congress and R. Denton was Chairman of
the Local Arrangements Committee. Profits
from the exhibition were given to the IOVST
and later transferred to the IUVSTA when the
new statutes were adopted.
The Third International Vacuum Congress
under IUVSTA sponsorship was scheduled
to be held in Stuttgart, with the German
Vacuum Society in charge of the local
arrangements. Since it was the intent
that an International Vacuum Congress
be held every three years, the Stuttgart
Congress should have been scheduled
for the latter part of 1964. At this time,
however, considerable interest had
developed in space research in Europe,
and P. S. Choumoff, Chief Engineer of
the French vacuum company SOGEV,
proposed an International Congress on
Vacuum Technique in Space Research
(Congrès International des Techniques du
Vide en Recherche Spatiale (CIVRES)) with
the support of the French Vacuum Society
and the French space organisation CNES.
This meeting was scheduled for about the
same time as the 3
rd
IUVSTA International
Vacuum Congress. To avoid a conflict
in timing, P. S. Choumoff, M. W. Welch,
IUVSTA President, and K. Diels, German
Vacuum Society President agreed to
advance the date of the CIVRES meeting
six months and delay the IUVSTA Congress
six months. The CIVRES meeting was then
held in Paris on 29 June-4 July 1964 and
the 3
rd
International Vacuum Congress in
Stuttgart on 28 June-2 July 1965.
This Stuttgart Congress was organised
on behalf of the IUVSTA by the German
Vacuum Society (DAGV) and the meetings
were held in the “Liederhalle”. K. Diels was
chairman of the Organising Committee
and was assisted by an International
Scientific Committee chaired by H. Adam
and a Local Organising Committee. The
Congress was sponsored by IUVSTA, by
prominent German vacuum firms and by
Messrs. Bosch in Stuttgart. The Congress
was attended by more than 700 persons,
coming from 28 countries. Several USSR
participants presented papers during the
Congress. The scientific program included
about 130 papers twelve of which were
invited. Four papers were presented the
day after the official closing of the Congress
in an educational session with experiments
on vacuum physics and technology. This
session was attended mainly by persons
from the teaching profession. The morning
sessions of the Congress were devoted
to invited papers with simultaneous
translations in the three official languages
of the IUVSTA. This was done visually in
a rather unique manner. On two screens,
in addition to the screen for showing the
slides, the text of the speaker’s manuscript
was shown in the two other languages.
The texts were kept in phase with the
speaker’s oral presentation. This method
of translation was very much appreciated
by the audience at the time, but was never
adopted afterwards, perhaps because of
the amount of preparatory work involved.
Gas flow, low pressure measurements,
sorption, thin films, particle accelerators,
space simulation and vacuum metallurgy
were quite evenly covered by the
invited papers. Short contributions were
presented in 13 afternoon sessions. Thin
films produced in vacuum and surface
phenomena had already begun to play
