Sir William H. Perkin (1838-1907) discovered mauveine, the world’s first synthetic dyestuff, in 1856. He and his brother Thomas produced mauveine from a factory on this site in 1857, and later alizarin, thus laying the foundations of the organic chemicals industry. This replaces a centenary plaque unveiled by Sir R Robinson in 1957.

This plaque replaced #31463
