Small addition to final paragraph made on 10 May 2013
Today I gave a talk at a conference in Berlin called Online Educa, in which I tried to meld the personal and the professional into one piece. So far as I could tell from the audience reaction this worked: but partially. (Link to the presentation I used [45 page 3 MB PDF, includes the script for the talk]; link to a somewhat "heavy breathing" video recording of the talk; link to other videos of talks at the conference on the Online Educa web site).
Below is a series of pictures I took yesterday (on 29 November) of sculptor Gunter Demnig and his co-worker embedding three Stolpersteine (stumbling blocks) into the cobbles outside 52 Oderstrasse, in Neukölln, Berlin. The Stolpersteine commemorate Selma Lewin, Martha Meth and Max Meth, and the pictures show descendents of the family at the informal ceremony that was held, and childred from a local school who had become involved in researching Selma, Martha and Max. Eight further batches of Stolpersteine - 18 in total - were embedded by Demnig on the same day in Neukölln. Between Tuesday and Friday of this week a total of 115 Stolpersteine were laid outside 36 houses all over Berlin. [I am in the process of arranging Stolpersteine to be laid outside the block where my grandparents and great grandmother last lived in Berlin, before they were taken to Terezin in Autumn 1942.] You may also be interested in this May 2013 piece by Andreas Kluth, the Economist's Berlin Bureau Chief.
