Jean Eugène Bataillon (22 October 1864 – 1 November 1953) was a French zoologist who studied embryology, fertilization and development.
Bataillon was born in Annoire, Jura, son of a stonemason and chose not to follow studies leading to a religious career and went to the Collège d’Arbois and studied philosophy while teaching at the Belfort lycée.
He then joined the faculty as a lecturer in zoology at Lyons and moved to Dijon the next year.
He initially thought it was osmotic pressure that was the trigger but later found that it could be reduced to just puncturing them with platinum stylets.
[1] One of his students was Chou Su who returned to China to teach zoology.
