On that evening when we were sitting talking at a hotel, I
got the impression that Jürgen Sens had many years ahead of
him, having just retired a few months before. On parting, we
both said we looked forward to seeing each other at the cele-
bration of Zino Davidoff's 100th birthday. But that good-bye
turned out to be our final one.
Jürgen Sens was a person who lived his life with deep aware-
ness, who gave enjoyment and pleasure their due place. In
other words, he did not allow them to dominate his thinking.
He closely resembles Zino Davidoff in that respect. At the end
of a workday, both sought and found the inner tranquility so
necessary to consciously enjoy life. Perhaps this impression of
Jürgen Sens makes the pain of his death somewhat more
bearable. Many of those who knew him would certainly agree.
To him and everyone else, my heartfelt thanks for all the
various kinds of support and assistance you gave me. With-
out exception, you were extremely helpful in allowing me to
create this manuscript. Whether or not the book succeeds is
something we will each have to decide for ourselves.
