Percy Carlyle Gilchrist FRS was a British chemist and metallurgist known for his collaboration with cousin Sidney Gilchrist Thomas on the Gilchrist–Thomas process, revolutionizing steel production. Their basic process made low-phosphorus steel from local high-phosphorus ores, reducing costs for British industry. Gilchrist was elected vice-president of the Iron and Steel Institute and a Fellow of the Royal Society. He developed the process in 1875-77, utilizing a converter to remove impurities through oxidation and lime addition. His contributions significantly impacted the steel manufacturing process.
