French botanist (1834-1895).
Père Jean-Marie Delavay (28 December 1834 – 31 December 1895) was a French missionary, explorer and botanist. He was perhaps the first Western explorer of the region which is now encompassed by the Three Parallel Rivers of Yunnan Protected Areas. Delavay was born in Les Gets, Haute-Savoie, in 1834.

While in France in 1881, on a break from his duties, Delavay met the natural history collector and fellow missionary Père Armand
