The FH Aachen and the Faculty of Medical Engineering and Technomathematics mourn the loss of Mr.

Prof. Dr rer.nat. Dr Stefan Sponagel

He passed away on 22 December 2009 after a long illness. The staff at the Jülich site are deeply saddened by the death of their sincere and highly esteemed colleague who, despite his illness, was dedicated to his students until the very end.

Professor Stefan Sponagel was born on 4 June 1949 in Viernheim. After completing his doctorate in mechanics at the TU Darmstadt in 1982, he followed his typical path of application-oriented modelling with a doctorate in rubber-metal components at the TU Kaiserslautern. On 1 September 1993, he accepted an appointment to the FH Aachen in the subject area of medical technology materials.

As head of the laboratory for biomaterials, Professor Sponagel remained true to his professional mission statement of interdisciplinary orientation by always being able to build a bridge between application and mathematics in his research. This was one of the reasons why he held various patents. However, his special commitment was to his students, to whom he felt deeply committed until the end.

In Professor Stefan Sponagel, we have lost a unique colleague who brought his whole person to his work. The esteem in which he was held went far beyond the boundaries of the university. On 4 June 2009, on the occasion of his 60th birthday, a mechanics colloquium was held at the Jülich site, at which renowned national and international scientists paid their respects to the seriously ill professor with a variety of lectures.

Prof Sponagel was someone who achieved an incredible amount in his life, but who, like so many others, was not spared the disease. However, he fought against it with courage until the end and even stood in front of us again in the lecture immediately after his treatments. For these reasons, this man deserves great respect and may he rest in peace!

Think of a picture - wide sea a sailing ship sets its white sails and glides out into the sea.
You see how it gets smaller and smaller.
Where water and sky meet, it disappears.
Someone says: "Now it's gone!"
Another says: "It's coming!"

Death is a horizon, and a horizon is nothing other than the limit of our vision.
When we mourn a person, others are happy to see them again beyond this limit.

In memory of Prof. Sponagel, may he rest in peace!

A unique and admirable person has gone on his journey.

Even if it was not always easy and many a bad word was spoken,
I am glad that I was still able to get to know him.
Rarely do people speak so openly about the truth of life as he did.
Rarely do people remain as strong and full of life as he did in the face of such serious illness.
My deep respect.

The integral of his life is now closed,
The sum of the memories that remain,
is always positive.
His duties and burdens now approach zero,
His freedom, however, strives towards infinity.

May he rest in peace.

My condolences to all those whose hearts are weighed down with grief so close to Christmas.

One suspects it in advance, but represses the fact that it could happen, as well as the finality that comes with the passing of a valued, respected, beloved person.

I am glad to have known Prof Sponagel, not only as he was last, but especially as he was a few years ago, when he was healthy. This is how I will remember him, with his dedication to science, his personal commitment and his humour.
The Jülich campus has lost a great person who fought to the end.
My personal condolences go especially to Mr Sponagel's family in this difficult hour!

Mr Sponagel, we will not forget you!
Rest in peace!

(Immanuel Kant)

Therefore, let us not forget this great man who taught us so much, so much more than "just" mathematics.
He was not only a professor, he was a mentor.
I will never forget the joy with which he told anecdotes about his grandson, what he said when you met him outside lectures, his view of life

And above all his will to fight.

Thank you for giving me the honour of learning from you.

The time

As long as you are young
You drive the time,
Which annoyingly hems,
Wildly before you,
That finally it brings
What you hoped for,
What you longed for.

But when you are old,
Then it drives you,
As you drove it,
And unwinds,
Swiftly and swiftly,
Your life's yarn-
Soon you will be over!

(Emil Claar)

Because time, he used to say, is the most important and scarcest commodity we have.
Rest in peace!

I have never experienced a professor who was so interdisciplinary and competent at a university of applied sciences. Whether maths, physics, materials science, mechanics or electrical engineering, Prof. Sponagel seemed to be more or less proficient in all these areas. Yet this was a professor who was very human and had an open and warm relationship with the students.

My sympathy goes out to the bereaved!

I wasn't at FH for very long and in the time I was there the good man didn't exactly make life easy for me, but the news still saddens me. I didn't know him well enough to say that I'm really deeply touched, but it's a real shame and sad and I'd like to offer my heartfelt condolences to his family and all the people he was a good friend/lecturer to, may he rest in peace.

Prof.Dr.Dr.-Ing. Stefan Sponagel,

with effective, simple and touching words you always managed to give us the love of study, a glimpse into science, conveyed the passion for the quest for knowledge. You will forever remain among us, because for us you remain a guide, the lamp in this darkness.

Rest in peace

There are people in the world who encourage and always stand behind you.
Mr Sponagel could stand in front of you and say that the maths exam you wrote was indecipherable, but the world didn't end because of that, you could still "read" it to him. He could look so childishly euphoric and at the same time unperturbed at a seemingly unsolvable task. Even if he wanted to tell us that any one of us could become President of America tomorrow, we would have believed him. So Mr Sponagel always encouraged students to pursue their goals, no matter how complicated it seemed.

There are people in the world who discourage by constantly criticising.
Mr Sponagel could stand in front of you and tell you that a written examination was simply not worth a better grade due to a lack of mathematical knowledge or cumbersome indices. He could be so tough and strict, but fair at the same time. He was like a kind of trainer-coach-father who demanded a certain discipline from us.

There are very few people in the world who can do both.
Parents, teachers and professors have this responsibility in particular. However, not everyone has the sensitivity to administer both in the right quantities at the right moments. Mr Sponagel was one of the few with the temperament to teach students in a colourful way without disturbing the seriousness of the subject, to be close to people without leaving his zone of authority, to hold strong opinions without offending the dignity of the other person. That's the professor I had the privilege of experiencing.

I don't believe that hope or answers went with him. Rather, he opened a door for us to continue where he left off or to accept the challenge that he himself had accepted. Another good man had to go. Good because he was optimistic, interested, profound, warm and compassionate. All in all, a professor out of a picture book, from which one likes to read to the next generations.
I can only thank you for the short but all the more enriching encounter, Mr Sponagel.

Prof Sponagel, you said to me on Friday when I was visiting you in Düren hospital that you wanted to go home: <<...Mr Deumo, just come and visit me on Monday...Then I'll be home.... I'll be discharged from hospital on Monday...The neurologist didn't find anything suspicious after all the examinations...>>

But I didn't understand what you were trying to tell me. But now... now I understand.
...We still had so much to discuss! So many unanswered questions... You still had so many plans...

Mr Sponagel, I will miss you....

You came, you left with a faint trace,
a fugitive guest in the land of earth;
Where from? Whither? We only know:
From God's hand in God's hand.
(Ludwig Uhland )

It was as if heaven
had silently kissed the earth,
that those in the shimmer of blossoms
only had to dream of it.

The air passed through the fields,
the ears of corn waved gently,
the woods rustled softly,
so starry was the night.

And my soul spread
wide its wings,
flew through the silent lands,
as if it were flying home.

(Joseph von Eichendorff)

Today we said goodbye to Prof. Dr. Dr.-Ing Stefan Sponagel...

For one he was a husband,
For one he was a father,
For one he was a father-in-law,
For two others,
A grandfather....

For some he was a colleague,
For many, a professor...

For some he was a counsellor,
For many, a Library...

[...]

But to me he was a professor,
No, not just a professor,
He was like a father,
No, more than a father,
He was a mentor, my mentor,

[...]

No, he was more than all that,
He's my friend...

A person whose life experience and life story,
will remain a lesson for us,
An incomparable example,
That makes you human,
A good person....

Stefan,
We will miss you,
You may now rest in peace,
Because I know,
You are better,
Where you are now...

Unfortunately, people die and we mourn.

But I think that even though Mr Sponagel has gone, there is much to be happy about after a brief moment of mourning.

He left us a lot and taught us a lot. As long as we remember that and look back on his life's work, we can be happy in our hearts. Because even though I didn't know him that well, I am firmly convinced that this man achieved something that not everyone has.
He changed the world and made it a better place, at least for a certain group of people. And that is what we should remember after all the mourning...

Today, 28 March 2011, I learn of the death of my mentor and teacher, Dr Sponagel, you have always and only been a supporter and patron throughout our time together in industry. You even came along to my last exam in numerical mathematics at the TH, determined to take over the chair for my benefit and were turned away by a snooty official. Even without this exam, I made my way through my so-called career in industry and you were always there with ideas, advice and explanations. I am very sad that you left so early and mourn with your loved ones. I would have loved to have seen you again, to have felt your inimitable, sharp sense of humour.Unfortunately, that is not possible and so all that remains is an adieu until we perhaps meet again in one of the higher dimensions of the universe, like your close friend Dr Ullrich Masberg, who took me to his heart in the Clouth days and who also passed away on 25 March 2011.Thank you for everything you gave and showed me.Klaus-Peter Zeyen and familyCologne
