* 31. Mar. 1899 in Zürich; † 27. Jan. 1994 in Zürich was a Swiss Cardiologist and published more than 100 articles and books about cardiology and was well known not only in Switzerland. He is also mentioned in the Historical Dictionary of Switzerland. To learn more about him just follow the link (short biography in German).
His “Legitimationskarte”, a previous version of the Swiss ID card, was issued in 1940.


His cancelled passport with some interesting visa was issued in 1961 and was 2 times renewed.
I could exchange these two nice documents with my Swiss fellow collector, which is almost my neighbour as he not lives far away from me in Zürich. Thank you Ernst for this nice swap. (I got also from him a 1951 Swiss Collective Passport, more about this document in the next upcoming article).
