Smacnego!
In May 2015 I taught an entrepreneurship course at the University of Economics in Katowice on an Erasmus exchange with Riga Business School.
You might find this story about my late friend and twin survivor of Mengele's twin experiments, Otto Klein interesting. In November 2000 I went on a day trip from Geneva to Krakow-Auschwitz with him, three other survivors and 150 Swiss schoolteachers. The trip was sponsored by Swiss B'nai Brith to teach Swiss teachers how to teach the Shoah during the spike in anti-semitism due to the litigation about the Swiss banks' dormant accounts.
