CY O'Connor was an engineer born in Ireland in 1843 who died by suicide in Australia in 1902. He had a successful career as a chief engineer in New Zealand where he built major railways. He then moved to Western Australia where he oversaw the construction of the Goldfields Water Supply Pipeline, a massive project to supply water to the goldfields. However, he took his own life before the pipeline was completed, overcome by stress from political attacks and investigations into his work. The pipeline was finally opened in 1903, achieving his greatest accomplishment after his death.
