I have the best memories of working for Prof. Kao as a novice some thirty years ago when he started the grand project of establishing the Faculty of Engineering at CUHK. He showed me the way to do things well, and with so much forbearance and generosity. He is the best role model ever, and his guidance will be cherished in my heart. What an amazing person and what a remarkable life that he has led. I am grateful I had the chance to know him and have worked for him. He will be deeply missed.
My sincere condolences,
Doris Law

(student from the same department)

I just came IE department for less than a month, but Kao's contribution has led me a deep impression on my mind ever since I got the offer. On the day he passed away, I just passed by his statue in SHB, and stood for a while thinking that how lucky our department was to have him as the founder. Then I received the letter to inform of his death.
I am so sorry to hear that. He is the father of all us IE student, is also someone who I will mention with great honor every time I introduce our faculty. Just a few hours ago, I took an interview and said: "Do you have any idea of our faculty? it's the one founded by Prof.Kao."
He is the source of IE people's confidence. Although he left us, we will still pass the confidence down through generation. Goodbye to the noble soul.RIP!

Charles was an idol, a mentor, and a friend to me. I probably would not have worked on “optical communication networks” for my PhD thesis were it not for the pioneering work of Charles. I would not have landed in HK, working in CUHK, were it not for the fact that Charles visited Bellcore, my previous employer, every summer in the early nineties. I most definitely would not have taken the many paths I had taken in CUHK over the years were it not for the encouragement and inspiration from Charles.

I found in my computer a photograph taken in 1999. The occasion was probably my family and Frank Tong’s family visiting Charles and Gwen during the Chinese New Year. Charles was showing a few hand tricks that rely on physical laws to my two kids who had no idea who Charles was. They were playing all sorts of irreverent and impolite pranks on Charles and Gwen, who just took it as good fun -- the very human and kind side of Charles and Gwen.

In Memory of Prof. Charles Kao, a giant in science, innovation, education, and administration.
My great respect and sincere condolences.

Raymond W. Yeung said:

(Relationship: colleague, friend, fan)

While there are many brilliant inventions in engineering, seldom do we find one that has no alternative. Optical fiber is one such invention. Prof. Kao asserted that there would be no alternative for optical fiber in 1000 years, but he added that one should not believe in experts, because he had not either.
We used to see Prof. Kao having lunch by himself at the Franklin Student Canteen from time to time. It had been our privilege and honor to be close to this extraordinary yet ordinary person. Charles, we all owe you a lot.

When I was a PhD student in waveguide optics, sponsored by STL in the 1980s, I was a regular visitor at the STL research labs in Harlow where Professor Kao did his early experiments on optical fibers. Many of the researchers there still remembered him as down-to-earth researcher: just like the rest of us! Professor Kao changed the world with his vision and predictions for optical fiber communications. He achieved so much but was always so respectful of others and modest. I shall always treasure the memories of him. When I joined CUHK as a lecturer in 1993, I received an invitation, with other newly appointed junior academics, to visit his official residence for tea in the weekend - he took the time to meet and nurture talents even the most junior of academic staff despite being so busy as vice chancellor of the university. He was a true visionary who led be example and understood the bigger picture for the future.

Professor Kao indeed among the most influential people in our Faculty of Engineering at CUHK. I was greatly indebted by Professor Kao for his futuristic vision in the internet and information technology. When he served as the Vice-Chancellor of CUHK, he founded our Faculty of Engineering as well as our Department of Information Engineering (IE) at CUHK. I was fortunate to be the first batch of undergraduate students admitted to the new Faculty under the 4-year Integrative Engineering Programme and I enrolled in the IE Programme in my second year of study. This brought me to the new world of fascinating information age, and made me acquaint the evolution of the modern telecommunication and networking technologies. I have also carried out research in optical fiber communications in my Ph.D. study. Prof. Kao’s contributions in optical fiber communications really enable the nowadays’ 4G/5G mobile systems, cloud computing, ultrahigh capacity long-haul optical fiber systems as well as internet of things, which greatly enhance the well-being of people. I would remember him and learn from his excellent scholarship & leadership.
My deepest condolences to Professor Kao’s family.

(Friend and colleague)

We have lost a very dear colleague and a faithful leader.
Charles Kao embodied two values that have left an indelible mark on the Chinese University of Hong Kong: independent thinking; and a commitment to promote scientific research. I’ll never forget what he said when I asked him why he still believed in fiber optic communications while most experts considered it is inconceivable: “No one ever proved it is impossible.” That is why he brought so much largeness of heart when he was the Vice-Chancellor of CUHK.
What a great man and he will sure be missed. He is a very special person in my heart. Not only was it enlightening to have conversations with him, but I've never met a more educated scholar. His death, though tragic, will not be in vain. And he has a great reward in heaven!

My sincere condolences,
Tony Lee

(Former colleague and friend)

Charles Kao was special to me. He gave me an opportunity to help establish an engineering faculty at CUHK. With his guidance, encouragement and support, I was able to recruit some best people in their fields to join CUHK. Many came because of Charles. The faculty now ranks among the best engineering schools.
Volumes have been written to honor him for his contributions to fiber optics and optical communication, which has made possible the internet revolution that has so dramatically benefitted humankind. I shall not repeat them here, except to say that I read one of his original papers in which he showed how the index of refraction should be varied in a fiber so to concentrate the light beam to minimize propagation loss. When I read it I was convinced that Charles would soon be recognized as a great scientist, and he was, many times, world-wide, culminating in the Nobel Prize in 2009.
Not to be overlooked was his contribution to education in Hong Kong. Prior to 1991, under the colonial rule, young people had very few opportunities to study engineering in Hong Kong. Charles initiated an electronics program at CUHK in 1970 and set up the Faculty of Engineering in 1991. Now aspiring engineers can obtain a university education second to none.
Charles was a gentle person, always polite to everyone, regardless his/her social station, friend or foe. He never wanted to harm anyone, always looked for the best in people. This trait marks a great man that he was.
We shall miss him, for his vision, wisdom and kindness.

Prof. Kao founded the EE department at CUHK. Without his hard work, there wouldn't be a world class EE department in Hong Kong. And I wouldn't be a EE graduate of the department. After I graduated, Prof. Kao went back to CUHK and became the Vice Chancellor. With his leadership, many world class researches were spawned out and formed the foundation of many advanced research work His Nobel prize achievement has made CUHK EE department name shine and bright worldwide. Today, I am working in the United States and I am very proud of telling my colleagues, IEEE friends and my employers that I am a EE student of Prof. Kao. I will remember him forever. RIP. My deep condolences to Mrs. Kao.
