TITLE: Who was in the Fields committee for ICM 1962 (the first appointed by IMU)?
QUESTION [9 upvotes]: Traditionally, at the presentation of the Fields medals at the ICM opening ceremony, the composition of the Fields medal committee is disclosed. This information can be found in the first volume of the respective ICM Proceedings (for older ICM, somewhat hidden in the presentation speech of the chair). That is, except for the 1962 ICM at Stockholm, the first for which the Fields Committee was appointed via IMU). It is only clear that Nevanlinna (who gave the presentation speech) was the chair:

After an interval, Professor Nevanlinna in his capacity of chairman of
  the  Fields  Medals  Committee,  read the report of the Committee 
  which was as  follows: [..] The  problem of suggesting names for the
  award of the Fields  medals has, since the last  congress, been
  entrusted to the International Mathematical  Union. To  prepare the
  names at this Congress in Stockholm, the Union  appointed a Fields 
  medals  committee.  This  committee has the honour to make  known its
  decision  here.

Some more details are given in the Secretary's report:

The  scientific  programme  was  drawn  up  in  close  cooperation 
  with  the   International  Mathematical  Union,  which  for  this 
  purpose  nominated   a    Consultative  Committee  with  Professor
  G. de Rham as  chairman.   The    Swedish  representatives  in  charge
  of the  scientific  programme  were  Professors L.  Gårding,  L. 
  Carleson  and  L. Hörmander.   Thus  a  first  meeting  was held in 
  Zurich in November  1960 followed  by  a meeting in Düsseldorf in
  January  1961. As  a  result  of  these  two  meetings the 
  "International  Fields  Committee",  that  elects  the  two  prize 
  winners, was  constituted.  Furthermore  a  list  was made  of 
  speakers to  be invited  to deliver  one-hour  addresses  on  chosen 
  topics  in  different   fields  of  mathematics.

From this passage, one might guess that there was an overlap of the Fields and the Program Committee (which would be a historical exception), but I couldn't find more explicit information in the volume. Does someone know more about the composition of the committee?

REPLY [3 votes]: Fields Medal Prize Committee 1962

R. Nevanlinna (chair)  
P.S. Aleksandrov  
E. Artin  
S.-S. Chern  
C. Chevalley 
H. Whitney  
K. Yosida

Only Aleksandrov was also in the IMU consultative committee, the other members were not. For the record, the 1962 consultative committee was chaired by de Rham, with IMU members Aleksandrov, Chandrasekharan, Eckmann, Hodge, Hopf, Montgomery, and Morse, and local Swedish members Carleson, Frostman, Gårding, Hörmander, and Pleijel.
