The postage stamp illustrated in this note, the first ever issued to honor a Chemistry Olympiad, was released on 15 June 2018 to commemorate the 50th IChO, which was jointly hosted for the first time by two countries, Slovakia and the Czech Republic. It took place on 19-29 July 2018, organized by Comenius University in Bratislava and the University of Chemistry and Technology in Prague, institutions that shared the management of both technical sessions and social events. Significantly, the 50th IChO had a record attendance of 300 students from 76 countries, a fitting milestone for the golden anniversary of the International Chemistry Olympiads.
The 51st IChO will take place in Paris on 21-30 July 2019, just a few days after the IUPAC World Congress and General Assembly, yet another reason to celebrate chemistry during the International Year of the Periodic Table. Dmitri Mendeleev, 150 years after introducing the first version of the modern periodic table, would be so proud of the students competing at the IChO!
