Charles Jurine (1751–1819) was a Swiss zoologist who, inspired by a letter by Lazzaro Spallanzani to the Geneva Natural History Society, set about showing that bats used their ears to navigate. He corresponded with Spallanzani, who confirmed his findings but their work was largely ignored until the 20th century when Donald Griffin and G. W. Pierce proposed echolocation. Notes Griffin, D.R.
