今天一個朋友告訴我Stefan早就不在了， 我震驚，你是說那個有超凡創造力的Stefan ?   那個超善良的Stefan ? 

我上網查了一下， 是他，難過！

我多年前有幸認識 Stefan， 做為同事但又不在同一國家， 每年見一兩次。Stefan總是笑眯眯的，見面給個大大Hug.  他看上去很隨和， 工作上卻很出色， 他為公司貢獻了很多有用的技術專利。 管理着美國的研發團隊。後來我離開那家公司就沒怎麼聯繫了。

在紀念Stefan的網上有人寫“ He was one of those "smartest guys you've ever met" ，

他是聰明，他是不張揚的聰明，總是耐心地解答別人的問題， ready to help. 

有同事寫道：

“You were not only the bright smart MR guru who explained MR concepts in such an easy way to follow,  but you were so kind hearted, the most humble credible person I have ever met. You were so generous with me in sharing your knowledge and time to make us successful. I will terribly miss you ”

Dear Stefan 
I am simply heartbroken at the news of your passing. What an immensely bright, generous, and delightful person you were to know and work with. I will miss you tremendously - it just won't be the same without you. -

這把一個活生生的Stefan帶了回來， 他是少見的smart 又kind hearted， 有人曾經告訴我， 這個世界上只有兩種男人： successful man or kind man.  Stefan向我證明了可以做到both。

他用行動告訴我們做人應該這樣：

I had met Stefan only recently at a pulse programming course in Cleveland. In that time I had come to like Stefan tremendously.  His knowledge and experience in MRI and his capacity for teaching were remarkable. I was so impressed that such a senior person took the time to spend so much time with us who were there to learn the basics.

記得有一次他出差來香港， 想帶個禮物給他太太， 我陪他去買， 他精心挑選白金項鍊， 讓我幫他試戴， 直到他滿意， 我能感受到他多愛他的太太，愛他的孩子。

。。。

有人寫到：”I'm a better person by knowing him“。 

The way he lived his life inspired many poeple around him ！
