No, Mark Von Hagen is
not the son of Victor Von Hagen. I don't know who Mark's parents are, but I found the entry for Victor in an old
Who's Who. Victor had one daughter by his first wife, and two daughters by his second wife; no sons listed.
Victor Wolfgang Von Hagen was born on February 29, 1908, in St. Louis. Mark earned his bachelor's degree in 1976, so he was probably born about 1954.
Prof. Mark Von Hagen received his Ph.D. in 1984 from Stanford University. I just ran across his name in connection with a lecture series at the Europa-Universitaet Vladrina, in Frankfurt/Oder; he will speak on Jan. 13, 2004, on "Ukraine Does Have a History: What Does It Mean in the Eastern European Context?" (The rest of the lectures are all on Polish or Ukrainian history; Frankfurt is on the German/Polish border.)
Today, incidentally, is the anniversary of the beginning of the Hungarian Revolution of 1956.
