In July 2019, we visited the D. I. Mendeleyev Institute for Metrology (VNIIM), the Mendeleev Museum-Archive in the Twelve Colleges Building of St. Petersburg University, and the Lomonosov Collection in the nearby Kunstkamera. At the VNIIM we were kindly hosted by Dr. Elena Ginak, Director of the Metrology Museum. For admittance to the Museum-Archive we corresponded with Dr. Igor Dmitriev, the director of the museum. In the Kunstkamera we were kindly hosted by Dr. Tatiana Moiseeva, Chief of the Lomonosov Museum from 2002 to 2009 and Scientific Secretary of the Lomonosov Commission of the St. Petersburg Scientific Centre of the Russian Academy of Science (2004-2014).
