Henri Édouard Prosper Breuil, often referred to as Abbé Breuil, was a French Catholic priest, archaeologist, anthropologist, ethnologist and geologist. He is noted for his studies of cave art in the Somme and Dordogne valleys as well as in Spain, Portugal, Italy, Ireland, China with Teilhard de Chardin, Ethiopia, British Somali Coast Protectorate, and especially Southern Africa.

The Swimming Reindeer is a 13,000-year-old Magdalenian sculpture of two swimming reindeer conserved in the British Museum. The sculpture was made in what is now modern-day France by an unknown sculptor who carved the artwork from the tip of a mammoth tusk. The sculpture was found in two pieces in 1866, but it was not until 1904 that Abbé Henri Breuil realised that the two pieces fit together to form a single artwork of two reindeer swimming nose-to-tail.
