[1] Arriving in Palestine in 1926, he was introduced to the region's prehistory by Alexis Mallon, head of the Pontifical Biblical Institute in Jerusalem, and Denis Buzy and P. Duvigneau of the Carmelite monastery in Bethlehem.

[3] Through Buzy and Duvigneau, he developed ties with the Bedouin of Wadi Khureitun, who would sell their monastery artefacts they found when clearing out caves in the Judaean Desert.

[2] One of these artefacts was the figurine Neuville dubbed the Ain Sakhri Lovers, which he was able to date by revisiting the cave where it was found and sieving through the sediment excavated by the Bedouin.

[2] In 1933, while exploring a cave in Jebel Qafzeh, near Nazareth, Neuville discovered the remains of five peoples buried in the Middle Palaeolithic.

After his death, his extensive collection of mollusc shells from the Levant, Sinai, North Africa and France was donated to the Hebrew University of Jerusalem, along with his library of malacological works.
