Honouring Dr. Louis “Lou” Siminovitch, the father of genetic research in Canada
Sinai Health is remembering one of Canada’s most significant scientific visionaries and founding director of the Lunenfeld-Tanenbaum Research Institute.
Dr. Louis Siminovitch – or “Lou” as he was affectionately known – passed away on Tuesday, April 6th. In May 2020, he celebrated his 100th birthday at a time when COVID-19 forced the world to socially distance, while simultaneously requiring urgent support from today’s top scientists.
Celebrations for the new centenarian may have been subdued, but they were plentiful – as many of his former colleagues and peers used the landmark occasion to sing his praises again and again.

“The better the science, the better the patient care,” Dr. Siminovitch used to say.
His work helped uncover the genetic bases of muscular dystrophy and cystic fibrosis and laid the groundwork for the genetic connections to cancer.
He contributed to the Nobel Prize-winning work in molecular genetics of Jacques Monod, Francois Jacob and Andre Lwoff during his years at the Pasteur Institute in Paris. An inductee into the Canadian Medical Hall of Fame, he was also both an Officer and Companion of the Order of Canada.
“Lou’s leadership to the scientific and academic community changed so many careers,” said Dr. Gary Newton, President and CEO of Sinai Health. “His work shaped Canadian medicine in a very profound way and his impact can be seen every day in the halls and labs of Mount Sinai Hospital.”
As much as he is respected for his research discoveries, Dr. Siminovitch is equally renowned as a scientific builder for the key roles he played establishing and developing outstanding medical research environments in Canada. These include the Ontario Cancer Institute at Princess Margaret Hospital, the Department of Medical Genetics at the University of Toronto and the Hospital for Sick Children Research Institute.
At age 65, when others might have contemplated retirement, Dr. Siminovitch was at the top of his game. Mount Sinai recruited him to build a first-rate academic research institute in 1985.
The Elinore and Lou Siminovitch Prize in Theatre bears his name and that of his late wife, a highly respected playwright.
Even in his final years, Dr. Siminovitch could still be found regularly at the LTRI in the office he shared with his daughter, Dr. Kathy Siminovitch, also a world-renowned geneticist and physician.
“He was truly a giant of Canadian science, and a trusted mentor to me,” said philanthropist Larry Tanenbaum. “His vision was the guiding light for what LTRI has become today. I’m so proud to see his legacy live on in the science that is changing lives and healthcare systems worldwide.”
In 2023, Mount Sinai Hospital will mark its 100th anniversary. While Lou will not be here to celebrate his own meaningful contributions, Sinai Health Foundation is honouring his achievements through a Sinai 100 Chair in his name.
