In memory of SYDE Professor Koncay Huseyin

Monday, July 18, 2022

The Department of Systems Design Engineering (SYDE) is saddened to announce the passing of Professor Koncay Huseyin on June 2, 2022, at the age of 85.

Professor Koncay Huseyin
Professor Huseyin dedicated 27 years to educating University of Waterloo engineers. He arrived at the university in 1969 as a faculty member in the Department of Civil Engineering. In 1972 Professor Huseyin moved to SYDE and served as department chair from 1978 to 1987. This was a formative era for the department and his leadership refined the curriculum to emphasize cultivating capable well-rounded people.

As a researcher, Professor Huseyin established himself as one of the world’s leading scholars in stability theory. He authored three books and was awarded the Doctor of Science (DSc) degree from the University of London. This degree denotes a stature above PhD and is awarded in recognition of substantial and sustained contribution to scientific knowledge. The legacy of his work in dynamics remains in the SYDE curriculum to this day.

In recognition of his dedication to teaching and learning, Professor Huseyin received the Centre for Teaching Excellence’s Distinguished Teacher Award in 1985. Current and former students organized his nomination through a letter-writing campaign that praised his conscientious teaching style. The letters and record of course critiques described his powerful intellect and ability to make the most difficult courses enjoyable for students. In 1997, he was awarded the title of Distinguished Professor Emeritus.

After dedicating his professional career to engineering, Professor Huseyin opted for early retirement to spend more time with his family and explore wide-ranging passions, from classical music to astronomy to driving a Plymouth Barracuda.

We extend our deepest sympathies to Professor Huseyin’s family. He is survived by his wife Tuncay, daughters Neyzar, Zuhal, and Hulya, son-in-law Cahit, and granddaughter Seda.

Share online condolences and memories of Professor Huseyin on the memorial website.

Professor Huseyin had such a sly smile when he told the stories! I remember like yesterday the twinkle in his eye as he anticipated our reaction. I found a book of Hoja stories when in Turkey a while back- not exactly the same thing as hearing Prof. Huseyin recount them but memorabilia nonetheless!

Professor Huseyin was a wonderful professor.  I greatly enjoyed Statics and Dynamics classes with him. He gave us the confidence to tackle any problem as he would show us how to solve almost every physics problem with a "free body diagram". He made physics classes so enjoyable and he always treated each and everyone of us with such respect.  

It is with great sadness that I hear of his passing, but I want you to know that he made a positive impact on so many of us.

I always smile when I think of Professor Huseyin. His kind demeanour, the Hoja stories, and his charming accent always made lectures fun, wectors and all :) . He will be missed but not forgotten, as everyone has made clear.

It was the highlight of the lectures when Professor Huseyin would come in and we’d all say “HOJA” HOJA" and he’d always have a new one! It's amazing that simple things like telling a joke, smiling, and laughing can relieve the worst pain/stress and angst. The world would be a better place if people told more HOJA jokes. Bless his surviving family!

Words that come to mind when I think of Professor Huseyin: titan and legend.

Professor Huseyin's whimsical stories always touched my heart and made me smile, in fact, even a passing thought of him and his anecdotes still does! We SYDE '90ers were SO LUCKY to have Statics and Dynamics delivered with such wisdom, charm, and grace - we were truly blessed in so many ways.

He was such a great professor. One of my all time favourites. Who can forget the HOJA stories? He was such a charming man with a beautiful accent and demeanor. Kind and helpful always and brilliant too.
