Jack, a baboon, was employed by the South African railways from 1881 to 1890 as a signalman.

His owner, James “Jumper” Wide, had lost both his legs in a railway accident and trained Jack to assist him with his duties. Jack quickly learned to operate the railway signals, and his remarkable accuracy and reliability earned him an official employment status.

He was paid twenty cents a day and received half a bottle of beer each week as part of his wages. Jack’s performance was so impressive that he never made a single mistake throughout his entire career.

An official investigation was initiated after a concerned member of the public reported seeing a baboon changing railway signals. The investigation confirmed Jack’s competence, and he continued to work without any issues.

Jack’s story became a testament to the extraordinary bond between him and his owner, as well as his incredible ability to perform complex tasks. His legacy lives on as one of the most unique and fascinating tales in railway history.
