Keith Edward McCarthy

December 27, 1957June 13, 2020

Keith Edward McCarthy died on Saturday June 13, 2020 at Yale New Haven Hospital after a brief illness. Only 62, he went way too soon. He leaves his sons Dillon (26), Gavin (24) and his daughter Kylie (21), as well as the mother of his children, Hilary Reid, to whom he was married for 26 years. He also leaves his sisters Kimberly Corzine of Colorado, Susan Reilly of Washington and his brother Craig McCarthy of Arizona. He is pre-deceased by his parents, Basil and Joan McCarthy and his brothers Christopher and Kevin McCarthy. He leaves behind a large group of friends and professional colleagues to remember him fondly and lament his loss. Keith was born in Fort Belvoir, Virginia, spent his early years in Colorado Springs and graduated from Colorado State University with a BS in Chemistry. He went on to earn his PhD in Chemistry at the University of California, Santa Barbara and his post-doctoral studies at Yale University. His professional career began at Syntex Research in Palo Alto, California then he came east in 1992 where he achieved great success in the pharmaceutical industry at Pfizer and Purdue Pharma. But Keith was about so much more than his professional credentials. He was dedicated to his children and instilled in them his humility, honesty, generosity, commitment to learning, love of sports and dedication to hard work. To his friends, he was a man to rely on in a crisis or to celebrate a great victory. A dedicated coach and teacher, Keith loved nothing more than helping a young person with their baseball swing, basketball shot or a chemistry problem. He was deeply committed to community service and served for six years on the Lyme Youth Service Bureau and four years on the Little League Board. He believed there was nothing more essential than science and he devoted his career to using science to improve the lives of others. But Keith was not a complete science nerd. He was fully human, in every way, and had the capacity to laugh at himself and appreciate his follies. Like all of us, Keith had his struggles, but in the end, his was a story of triumph as he found a way to make peace with himself and those he loved the most. In one of their last conversations, he told Dillon that this was the happiest he had felt in years. If you would like to remember Keith with a gift, please consider a donation to High Watch Recovery Center (Kent, CT), Aware Recovery Care (North Haven, CT) or your local AA chapter.

Keith was one of the most kind, compassionate, intelligent and caring individuals whom have ever walked the face of this earth. He genuinely cared about others and embraced the values of service to others. I was blessed to meet him while he overcame obstacles in his life. He embraced them with humility and grace.

Keith’s legacy to use all is one of hope, inspiration and serenity. I was so very proud of him and privileged to call him a friend. I will miss him terribly, and the conversations that we enjoyed together.

Rest In Peace, Keith, may God bless you in all ways and always and may He continue to hold you in the palm of His Hand.

You may be gone, but you will never be forgotten. My condolences go out to his entire family and to all those whose lives were enriched by his presence. I will miss you and until we meet again, watch over us all. We may his lost you in life, but Heaven has gained another angel.

Love you my friend.

Keith and I worked together at Rhodes for many years. He was absolutely brilliant but so "normal". We had many conversations about family and he was always so proud of Dillon, Gavin and Kylie's accomplishments. I had the pleasure of working with both Dillon and Gavin when they were summer interns. Keith's positive influence on his boys was crystal clear. They were such a pleasure to work with and both carried their dad's great personality and work ethic. Keith was a great man and will be greatly missed.

I met Keith at Pfizer and our shared memories of Syntex were an instant connection. He was always a joy to talk to and his humor, humanity, decency and intellect always left me feeling better. Every time we met afterwards, in and around Old Lyme, I always left feeling glad we had that interaction. He was a great man and a great loss. RIP.

I was shocked and saddened to learn of Keith's recent passing. I worked with Keith, directly and indirectly, during his time at Pfizer in Groton CT. He was an excellent chemist and a wonderful colleague and mentor of mine. He had a great sense of humor and the ability to see the big picture, which helped me during times when my research had run into a brick wall and I needed encouragement. I am so sad for all of Keith's family and wish to send them my best wishes and condolences.

So very sorry to hear of Keith’s passing. He was an awesome soccer coach to Steph. At little league meetings he always made me laugh, but in turn was always to voice of reason. Prayers to the family.

I’m very sorry to hear this. I only knew Keith through work at Pfizer, he sounds like a great all-around guy. Keith had the gift of talking to people then really listening to the answer. My sincere condolences to his family.
