fessor C. F. Baeschlin of Switzerland. All who have been interested in photo- 
grammetry during the past generation understand the debt of the International 
Society to Professor Baeschlin. An eminent geodesist, he also saw the possibili 
ties of photogrammetry and held it to a true course of scientific and mathe 
matical development. 
I always remember his discussions, full of sound, common sense and friend 
ly counsel as well as scientific value. Fie not only contributed to the scientific 
development of photogrammetry but he is responsible for the continuance of 
the international archives at a time of much struggle and indecision. In hono 
ring the contributions of a man such as Professor Baeschlin, the Internationa] 
Society honors itself. Fie is the President of the Association of Geodesy, of the 
International Union of Geodesy and Geophysics, in addition to his activities 
in photogrammetry. 
We are very sorry indeed that he could not be here to share our discus 
sion in this Congress; an accident of transportation at the critical time when 
all Americans crowd steamers and aircraft to return home after enjoying a 
pleasant summer in Europe prevented him from getting here. 
Prof. Zeller: Mr. President, Ladies and Gentlemen: 
I wish to thank very warmly the International Society of Photogram 
metry and its President for the honor which is now given to my colleague. It 
is not only an honor for Professor Baeschlin, it is also an honor for all Swit 
zerland. I know Professor Baeschlin will be very pleased and will feel very 
much honored by this award. And once again, I wish to thank very warmly 
the Society on his behalf. 
Professor Dore: It gives me great pleasure and great honor to propose 
the nomination as Honorary Member, Dr. Umberto Nistri. The history of 
the work of Dr. Nistri is very well known to all international photogram- 
metrists. He was a pioneer of this science. It was as far back as 1915, if I 
remember, when he started his work during the First World War. He was a 
photographer, also an aviator. He knew very well after that how to combine 
both and to find solutions to the problems of aerial photography, solutions to 
which he was always faithful in all of his life afterwards, which he always tried 
to improve upon. 
He always had faith in the double optical projection. He has worked in 
various fields, has achieved results which we all know and which we all admire. 
The proposal of the Italian delegation is the expression of this admiration 
which is ours for Dr. Nistri. We are sure this admiration is that also of all 
photogrammetrists in the international field. 
I could not very well here go into details, but I remember the first in 
strument which Dr. Nistri worked upon, which led him to the construction 
of the photocartograph — then he developed other instruments working more 
and more until he has brought to being such wonderful instruments as we have 
been able to see here in Washington. 
So, it is to recompense a life which was entirely devoted to photogram 
metry with enthusiasm, with a great intelligence, that we propose now that 
you are willing to all acknowledge by granting this award to Professor Nistri. 
In advance, I wish to thank the International Society for this honor. 
Dr. Nistri: For fifty years I have devoted all of my thought and all of my
