The Story of the Periodic Table

13 - 30 August 2019, London, United Kingdom

The United Nations have proclaimed 2019 to be the International Year of the Periodic Table of Chemical Elements since it is the 150th anniversary of the publication of Dmitri Mendeleev’s first Periodic Table.  But was it really the first?  St Catharine’s College is proud to exhibit its fine collection of material relating to the early development of the Periodic Table.  Starting from the first list of elements which emerged around the time of the French Revolution in the late 1780s, and the first list of atomic masses drawn up by Manchester chemist John Dalton, we explore why six different chemists from around the world each came up with their own versions of the iconic table in the 1860s.  
The very first person to arrange all the then-known elements by mass and then look for the repeating properties of related elements was the French mineralogist Alexandre-Émile Béguyer de Chancourtois in 1862.  Béguyer plotted his elements around a cylinder or helix with a circumference of sixteen atomic mass units and found elements with similar properties aligned in vertical groups down the cylinder. This coloured chart, over 1.5 metres in length, was published in very limited numbers and is now incredibly rare.
In addition to Mendeleev’s first published versions of his table, including one signed by the great chemist himself, earlier forms created by two British chemists are also featured.  Two new works of art specially created to mark this important anniversary will also be on display.  One is a spiral made from precious metal, the other is a macramé version containing more than 180,000 knots.

In addition to this wonderful collection, a unique classroom periodic table dating from 1879 – 1886, believed to be the oldest in existence today will be displayed. This exhibition will see this artefact, loaned by the University of St Andrews, on display to the public for the first time in over 100 years.
The free exhibition will be held across the Fish and Science Rooms in the Royal Society of Chemistry, Burlington House.
The exhibition will be open to the public from Tuesday 13th August – Friday 30th August inclusive (closed 24th – 26th August) at the following times (no pre-booking required):

Monday – Thursday: 09:00 – 17:00
Friday: 09:00 – 20:00
Saturday 17th & Sunday 18th August: 10:00 – 16:00.
