After constructing a trial plant at his home on Skipton Road, making it the first house in Yorkshire to have gas lighting and heating; he built a town-sized plant to supply Harrogate. After Parliament Street became the world's first route to be lit by water-gas, newspapers commented: "Samson Fox has captured the sunlight for Harrogate." After donating the town's first fire engine, and building the town's theatre, he was elected mayor for three years, an unbroken record.
