The first meeting of the "European Mathematical Psychology Group"
(EMPG) took place in April 1971, at the initiative of Jean-Claude
Falmagne. At that time, Jean-Claude had the feeling that mathematical
psychologists in Europe were suffering from a sense of isolation, and
that they had to oversimplify and `smooth' their presentations at
general conferences. He thus issued an invitation to a gathering that
would allow for more mathematical sophistication. Of the thirty
invitees, all came! The meeting took place at the `Maison des Belges'
of the Cite Universitaire in Paris, 1971.
Since then, there has been a European conference on Mathematical
Psychology, organized by a curiously rather informal group, almost
every year (there were even two of them in 1971). In acknowledgment
and admiration to Jean-Claude's foresight, a special session will take
place during the 35th EMPG meeting and its announcement arrives on a
day that has a particular meaning to Jean-Claude. Happy Birthday,
