Jack ran railway signals for nine years without one mistake. 🚂 . . . After signalman James Wide lost both legs, he purchased a chacma baboon in 1881 and trained him near Uitenhage, South Africa, to pull levers and operate signals. Jack reportedly worked for about 9 years and passed an official test. The railway ultimately employed the baboon instead of firing his human partner.
