Into our third century


2017 marked the 200th anniversary of Johnson Matthey. Back in 1817 we opened our doors as assayers, testing the purity of precious metals, and the business quickly expanded thanks to the vision and determination of our founders.

But the world moved on. And so did we.

Today, our science and research touches some of the most pressing challenges faced by our planet and its people. Our technologies are making the planet a cleaner, healthier place and improving people's lives across every continent.
