[GAP Forum] Joachim Neubüser

[Bettina Eick]

Dear GAP Forum,

with immense sadness we would like to inform you that Joachim Neubüser
passed away on Saturday, September 25, after a long illness. He was the
founder of the GAP System and also one of the main initiators of
Computational Group Theory in its early days.

Joachim Neubüser was born in 1932 in Belgard in Pommern (now Poland)         
and obtained his doctorate in 1957 at Kiel under the direction of
Wolfgang Gaschütz. From 1969-1997 he held the chair at Lehrstuhl D
für Mathematik at RWTH Aachen, Germany, where he built up, arguably,
the foremost research group in Computational Group Theory at that time.

Many modern group theoretic algorithms have been influenced by his work
and the GAP System, of which he was the leader until his retirement 1997,
is still one of the world leading computer algebra systems today.

As two of his doctoral students, both of us owe much of our education
in group theory, and in algorithms, to him.

In Gratitude,

   Bettina Eick and Alexander Hulpke
