Dr. Hans-Georg Weinig
IUPAC/German Central Committee for Chemistry
In order to represent the chemical interests of the Federal Republic of Germany in the IUPAC (International Union of Pure and Applied Chemistry), the "Federal Committee of German Chemistry", now the "German Central Committee for Chemistry" (DZfCh), was founded in Göttingen in 1952 at the suggestion of the GDCh.
The DZfCh is therefore the German member organisation (the so-called National Adhering Organisation, NAO) of IUPAC, i.e. all matters concerning IUPAC are regulated by the DZfCh. The Managing Directors of the DZfCh are based at the GDCh Office. Its members today include the following organisations:
DECHEMA e.V.
German Bunsen Society for physical chemistry e.V.
German Rubber Society e.V.
German Scientific Society for Sustainable Energy Carriers, Mobility and Carbon Cycles e.V.
German Chemical Society e.V.
Colloid Society e.V.
German Chemical Industry Association e.V.
The Chair of the DZfCh is Prof. Dr. Dr. h.c. mult. Evamarie Hey-Hawkins, Leipzig University. Dr. Hans-Georg Weinig, GDCh, has been Executive Director since 1 January 2021 Dr. Hans-Georg Weinig, GDCh.
From 2002 until the end of 2020, the then GDCh Executive Director Prof. Dr. Wolfram Koch was also Executive Director of the DZfCh. From 2008 to 2015, he was a member of the IUPAC Finance Committee. He was IUPAC Treasurer for the 2022–2025 term of office.
Through the Affiliate Membership Program, chemists can become individual members and thus work more closely with IUPAC.
Benefits:
• free electronic journal Chemistry International
• 25% discount on IUPAC books
• 10% discount on IUPAC symposia and congresses
The annual fee for GDCh members is €26. Cancellation is possible at the end of the year, provided it is received by the GDCh by 30 September.
