The ceremony that traditionally marks the anniversary of Louis Pasteur's death will be held on Tuesday September 30 this year.

Given the current works on the future museum and the fact the crypt is inaccessible, the ceremony will take place in the entrance hall of the Emile Duclaux building.

All staff are invited to gather at 12 noon for the commemoration ceremony at which the Institut Pasteur President Yasmine Belkaid will give an address, followed by the laying of a wreath in front of Emile Roux's tomb near the Metchnikoff building.

Pasteur, his wife, and his daughter Marie-Louise made this trip on 20 November 1878, when Pasteur wanted to respond to Claude Bernard's posthumous writings and prove, once again using grapes, that spontaneous generation did not exist.
