Zoo keepers in England had to learn French in order to speak to baboons coming from a French zoo, because the animals didn’t respond to English commands.
Baboons were employed as goatherds by the Namaqua people in the 1800s right through till the 1960s. They would protect the herd and lead them back at dusk, often whilst riding one of the larger goats like a horse.
During the late 1800s a baboon was employed by the railroad as a signalman. He never once made a mistake and worked for the railroad until his death.
19 Baboons from Paris Zoo sent to a national park in England were unable to understand English commands but were fully cognitive of French words, forcing their English keepers to learn French.
