Pierre Louis Boiteau was a French botanist, born on 3 December 1911 in Cognac and dying on 1 September 1980 in Orsay, Essonne.

He was initially in charge of the green spaces of Antsirabe and created the Parc de l'Est there.

Grimes asked him to accompany him to the leprosarium of Manankavely, on the road to Tamatave, where speaking Malagasy would allow him to come into contact with a traditional practitioner.

The financial benefits allowed the creation of the Malagasy Institute of Applied Research, which still exists though its two co-founders have died.

On 1 September 1982, the Madagascar post office released a stamp with the effigy of Pierre Boiteau.
