The IAP’s 75th anniversary

The Institut d’Astrophysique de Paris (IAP) was first created under the Front Populaire in October 1939, as part of the CNRS. The institute celebrated its 75th anniversary on October 11th 2013.

This was the opportunity:
- To set up an exhibit open to the public, looking back at IAP’s history;
- To make a film entitled “75 years of IAP”, directed by Jean Mouette and produced by CNRS Images;
- To hold an exceptional seminar entitled “Lessons from the Past for the Future of Cosmology”, hosted by Professor J. Peebles from the University of Princeton;
- To give presentations on the history of IAP and the research led in the Institute.

This even t was also associated to the Fête de la Science (“Science Festival 2013”). The lab opened its doors to the public on Saturday 12th and Sunday 13th of October.

The film

The color film lasts 24 minutes. Several French and foreign researchers and engineers are interviewed and they, discuss their work and mention memorable individuals who participated in the IAP’s development, such as Jean Perrin or Evry Schatzman (CNRS gold-medal winner in 1983).

To watch a version of the film with English subtitles, after clicking on the link below, please ensure that on the CNRS website you have selected "English" as the language. If not, click on "English" on the CNRS page, and then once more on the link below.


The exhibit

The exhibit was installed in the institute’s entrance hall from October 11th until December 31st 2013, and was split in two parts, both of which dealt with several subjects described with pictures and posters. Several books, scientific tools and technical accessories were exhibited as well.

The exhibit was coordinated by Jean-Pierre Maillard (IAP), along with many IAP employees. Graphic design: Marie Aumont (Michel & Michel).
