Jack, a baboon, worked for the South African Railways between 1881 and 1890. He earned 20 cents a day and half a pint a week. During his time on the job, Jack never made a mistake. Jack was a chacma baboon who assisted James Wide, a paraplegic railway signalman who had lost his legs in an accident. James trained Jack to help him with his daily tasks, and eventually Jack learned to operate railway signals under supervision, demonstrating great accuracy. Jack's reliability made him famous, and in his nine years of service, he never failed. Jack died in 1890, and his skull is preserved in the Albany Museum in Grahamstown, South Africa, as a tribute to his unique work in the railway industry.
