Guided tour with the former rector, Prof. dr. Georg Unland
on 26 January 2019, 3 pm about the mineral paradise Namibia

On the centenary of the donators' birthday Dr. dr. h.c. Erika Pohl-Ströher in the terra mineralia, permanent exhibition of the TU Bergakademie Freiberg, will be an exclusive guided tour with Prof. Dr.-Ing. Georg Unland. On Saturday, January 26, 2019, at 3 pm, Prof. Unland, former Rector of the TU Bergakademie Freiberg, initiator and founder of terra mineralia, former Saxon Minister of Finance and even a passionate collector of minerals, will guide interested guests through the collection of the donator from Saxony.

Dr. Erika Pohl-Ströher (18.01.1919 - 18.12.2016) has gathered in 60 years one of the most valuable private collections in the world, which can be seen since 2008 in the Freudenstein Castle, in a modern designed exhibition and since then lured almost one million visitors from near and remote. Although Erika Pohl-Ströher has collected the finest minerals from around the world, one of her favorites was the former mine in Tsumeb, Namibia. From here you will find fascinating minerals of outstanding quality, size and color that will delight laymen as well as connoisseurs. These include e.g. Azurite, Anglesite, Dioptase, Mimetesite, Smithsonite and many other colorful treasures. The donor himself visited the land, famous for its rich mineral treasures, several times, bringing together a substantial collection of minerals.

Also Prof. Georg Unland is a connoisseur of Namibian sites. As a collector of minerals, he not only acquired minerals locally but also searched for them himself. Prof. Unland visited active and disused mines, talked to local miners and was able to get a very detailed picture.
