Janssen Medal (French Academy of Sciences)

The commission formed to decide on the first recipient of the medal selected the German physicist Gustav Kirchhoff for his work on the science of spectroscopy.

However, Kirchhoff died aged 63 on 17 October 1887, a few months before the award would have been announced.

Rather than chose a new recipient for the award, the commission announced at the Academy's session of 26 December 1887 that the inaugural medal would be placed on his grave, in "supreme honour of the memory of this great scholar of Heidelberg".

A statement in the 1889 volume of Comptes rendus de l'Académie des sciences clarified that the award would be presented annually for the first seven years, and then biennially from 1894 onwards.

Janssen founded the Academy award, and was a member of the inaugural commission.
