In memoriam: Prof. Dr. Karl Strehmel

On 12 December 2023, our highly esteemed colleague Karl Strehmel, university professor and founder of the NUMDIFF conference series, passed away after a short, serious illness.

Karl Strehmel was a great mathematician and scientist who, even in times of German and European division, worked with great commitment and skill to promote international scientific cooperation that transcended borders. In the early 1980s, he founded the "Numerical Treatment of Differential Equations" seminars, which have since brought together many leading international experts in this field at the NUMDIFF conferences at Martin Luther University. We will commemorate him at NUMDIFF-17 in September 2024.

We remember with gratitude an academic teacher who opened up new horizons and inspired enthusiasm for his field.
