Periodic celebration
The United Nations has proclaimed 2019 as the International Year of the Periodic Table of Chemical Elements being 150 years since Mendeleev produced the first version. An 1885 version, printed in Vienna by Verlag v Lenoir & Forster, has been found at the University of St Andrews. It was bought by mail order in 1888 for three German goldmarks, the equivalent of about €20/$22/£17 today.
