GLEN DE VRIES Obituary

DE VRIES--Glen, entrepreneur, philanthropist, aviation and space enthusiast, died on November 11, 2021. Digital health visionary and trailblazer, he transformed clinical trials forever. Glen earned a Bachelor's degree in Molecular Biology and Genetics from Carnegie Mellon University in 1994. He endowed the chair of the dean of CMU's Mellon College of Science in 2018 and later became a trustee of the University. His book, "The Patient Equation" envisioned a future of medicine inspired by his decades of experience in life sciences. Glen was a bench scientist working on prostate cancer at Columbia University in the mid-1990s when, with colleagues and friends, he had the idea of making electronic research infrastructure the foundation for a new generation of clinical trials. To that end, in 1999 he and Tarek Sherif co-founded Medidata and built it to become the world's most-used clinical research platform. For more than two decades, he dedicated his life to powering smarter treatments and a healthier public. Captain Clinical, as Glen was fondly known, had lifelong aspirations of going into space, and on October 13, 2021 that dream became a reality as a member of the Blue Origin NS-18 crew. He was dedicated to using his space journey to improve life on earth, and actively supported organizations like Water.org to change lives with access to safe water. de Vries was an instrument-rated private pilot who enjoyed flying his small plane, and a large model of Blue Origin, made out of Lego, was taking shape in his apartment when he died. Glen de Vries was a man of many talents. Blessed with a quick and mischievous sense of humor, he sought joy everywhere and made it where it was lacking. When his company started doing business in Japan, he became fascinated by the culture, taught himself the language and was able to make his first major presentation to a Japanese audience in its own tongue. In awe of his uncle's mastery of the guitar, he took up the instrument and played lead in a band he formed with friends in 1995. Inspired by his mother's success at ballroom dancing, he became a very good dancer himself. He became a trustee of Dancing Classrooms, which works with schools and community organizations to cultivate essential life skills in children through the art and practice of social dance, and he was its chairman for many years. Glen is survived by his mother, Madeline de Vries Hooper, and his father, Alan de Vries; sisters Lizzy de Vries and Catherine Hooper, and stepfather Ian Hooper.

I joined Medidata in July 2017. Right after I joined, on a bright and sunny day, I went up to the ninth floor to say hello to Glen and Tar. I saw Glen was standing in front of his laptop and concentrating at work. I walked into his office and introduced myself. Glen smiled at me and was so friendly asked me about which department and what project that I was working on. That was the first time I talked with Glen. To me, Glen is a charming leader. He attracts everybody's attention when he was talking. He knew the Medidata business inside out. On top of it, he was so technical savvy, he kept his eyes on all the new technologies and what happened in the industry. I feel deeply sad when I heard the tragedy. He will be remembered forever!!!

I met Glen at Columbia Presbyterian in the 90's. He and Ed Ikeguchi brought me over to Medidata. He provided an opportunity and was there for me during it all. I seek solace in that I did tell Glen before the Blue Horizon flight how proud I was of him and how he was a true innovator and so inpirational. I will truly miss Glen and that smile. My condolences to the family.

It has been a joy knowing Glen for the 17 years I have been working in Medidata. A human being who brought light and joy wherever he went. I will never forget his smile - it stayed on his face and made everyone welcome. He lived his life the way he wanted to but kept a pulse on serving humanity and bringing education and cure to a large population that desperately needed it. Glen was both a leader and a visionary. His dreams will live on. My sincere condolences to his bereaved family, parents, sisters, friends, and the larger Medidata family.

I will dearly miss Glen with one consolation. He has left behind such a treasure of memories, they will tide my way in days to come.

Om Shanthi.

Just over 4 weeks ago I was so glad to reconnect, from a distance, with everything that Glen was up to. When I heard he would FINALLY meet his goal of being in space, even for such a short time, I was so joyful. In high school everyone knew how much he loved science and space. What I want people to know is how much he loved life. If you were his friend you were seen and appreciated. HIs laugh was infectious and he cared for people in his sphere. Clearly his work showed he cared for all people. 4 weeks later and I am struck numb. This tragedy is so hard to manage. I send Glen's family and all of our high school friends enormous hugs. He will be missed and I hope his memory is eternal.

Glen was the best roommate one could have and an even better friend. I was blessed to have shared a room or apartment with him for 3 years. He indeed and literally lit up any room he entered with a huge personality that was both gregarious and humble at the same time. I've spent the weekend being bombarded with memories of our times together. I've smiled and laughed and cried a lot. I've felt a lot. And that's what Glen's effect was on nearly everyone he met. An infectious influence to feel emotion. You would "feel more" after interacting with him, and you'd come away being a better person as a result. I'm going to miss my dear friend, and I thank him for making me a better person having known him. - Brad

While I did not know him that well, he was always approachable and conversational when I would run into him in the New York Office. To me he was and is the essence of Medidata and all it strives to be.

My deepest condolences to Glen´s parents, sisters, family, friends, fellow colleagues, and to his best friend-brother-Tarek. Glen´s legacy and vision will live on and be carried by the countless people he touched and benefitted during his time on this planet.

A month ago we cheered Glen on and counted down from the 6th floor when he blasted off into space, with Captain Kirk!! And who of all people drives Glen and his crew mates to the rocket...Jeff Bezos!! Talk about epic! My kids remembered Glen and Tarek from bring your children to work day at Medidata a few years back and they couldn´t wait to watch the launch video when they got back from school. It was actually the first day-maybe ever-that my kids asked me how work was today. We are all so happy that Glen got to live his dream of going to space. He got his astronaut wings from Jeff Bezos last month and now he has his heavenly wings from the Lord.

So much has been said about Glen from people who knew him much more closely than I did. I am proud to say that I had the privilege of working with him.

To the man who didn´t need a script for an earnings call and was always the most passionate about our great company-Medidata. Godspeed, and fly high @Captainclinical

Glen was a great person - a down-to-earth genius who believed in a better world. It´s a blessing that he got to see that world from beyond the clouds. Thank you, Glen, for being brave enough to dream big and think disruptively. Your ways of thinking has stuck with me well past working with you at Medidata. And also, thank you for being Medidata´s biggest fan of MDSOUL. You will be missed.

May God bless his soul, and comfort the family, friends, and all who love him.

God speed, Captain Clinical.

Glen was an inspiring, joyful visionary. It was always a pleasure to be in any room with Glen, whether it was real (the legendary parties!) or virtual (the many All Hands meetings). None of us ever left an encounter with Glen feeling less than inspired and enthusiastic about furthering his and Tarek's vision of making clinical trials better, helping patients through their journeys. For Glen, the only direction was forward; for all of us who had the honor of working with him, we'll return the honor by forging ahead, striving for excellence as he modeled it. He was unforgettable and epic. May his family, friends, and loved ones find peace, comfort, and strength in memories and in knowing so many colleagues are also mourning for a life well-lived, albeit far too short. Rest in peace, Glen.
