Johannes Peter Müller
In the 1850s, the zoologist Carl Vogt visited Villefranche and studied the planktonic fauna found in the bay, notably the gelatinous zooplankton (Vogt 1852). He was followed by Johannes Peter Müller and Ernst Haeckel who both described planktonic protists, radiolaria, from the Bay of Villefranche (Müller 1858; Haeckel 1860).
