Back in 2017, the UN General Assembly announced that 2019 would be the International Year of the Periodic Table (IYPT), celebrating 150 years since Russian scientist Dmitri Ivanovich Mendeleev published his periodic table in 1869. The table is regarded as one of the greatest scientific findings and the most significant reference for chemists.  

At Johnson Matthey, chemistry is at the heart of what we do. Throughout the years, our scientists have used the periodic table to understand the inter-relationships of elements, help promote sustainable development and solve some of the world's biggest challenges.

Below you can read more about our history and connection with the periodic table, and delve into our other related content, as we pay homage to Mendeleev's greatest achievement.

Creating our human periodic table

To mark our affiliation with chemistry's most iconic image in true JM style, our finalists at our global awards ceremony in January teamed up to create our very own human periodic table. Gathering nearly 150 of our finalists at the back of Hintze Hall, the spectacular space at London's Natural History Museum, home to Hope the whale, we asked our finalists to hold up tiles as we snapped the memorable image from the balcony above.

Check out our time-lapse video from our global awards ceremony below. Did you see our finalists leaving their tables to create our human periodic table?
