Tolix
Xavier Pauchard was born in 1880 in Le Morvan, known as the green heart of France. Unsurprisingly wood was the most important construction material but despite that, he and his father and grandfather before him were zinc roofers. In 1907, Pauchard discovered that he could protect sheet metal from rusting by dipping it in molten zinc, or galvanising it. Ten years later, he set up a factory making steel household items and eventually registered his trademark symbol as Tolix, by which name the company is still known.
