@dagmaraka,
I met him once when I traveled to Praha the first time in 1975. I was an American student but in school in London. I brought with me hidden magazines depicting the dissidents in Praha.
It was a dream to be the first of my family to travel to Czechoslovakia to see relatives face to face after many letters and an International call in 19 70.
Rudolf was at the dinner given by close friends - the Hasekovas. Anna Slanska was there. Rudolf told me a story about working for a newspaper. He had found out that several people were corrupt at the newspaper. he reported this to his supervisor who turned out to be part of the corruption as well. They tried to fire Rudolf but were too afraid of all the powerful people he knew. He laughed.
