John Walker was born in Stockton in May 1781 and was a chemist by trade occupying a shop on Stockton High Street. He experimented with different combustible substances in his home in 1826, and by chance he scraped the mixing stick on his hearth, causing it to splutter and catch fire.
Stockton councillor Norma Wilburn said: 'We were delighted to welcome the BBC. The story of John Walker's friction match shows that Stockton-on-Tees has always been an innovative place to live and work.'
