Duckett Funeral Home of J.S. Waterman & Sons

656 Boston Post Road, Sudbury, MA



March 15, 1949June 25, 2020

Stewart Mueller passed away on June 25, 2020 after a prolonged battle with lymphoma. He is survived by his loving wife, Deborah and his children Jon and wife Sarah of Wilmington, MA and Kathryn of Cambridge, MA; sister Shirlee Hattem and her partner Hank Weil of Frisco, TX; niece Jennifer Wells and her husband Shane of Frisco, TX and their children.

Stu was born in Manhattan on March 15, 1949, the son of the late Michael and Lottie Mueller. He grew up in Brooklyn and the Bronx, where he enjoyed building stereos and tinkering with radios. Through his father, he developed a love of cars and of building car models. He also developed a love of city life – museums, long walks and exploring by subway. After graduating from the Bronx High School of Science, he continued his education at the City College of New York, majoring in Geophysics. He later received an MS in Pharmaceutics from Temple University and an MBA in Technology Management from the University of Phoenix.

Stu began his nearly fifty-year love of the pharmaceutical industry with the FDA as an Investigator and advanced to Drug Specialist and Supervisory Investigator. While there, he met his future wife, Deborah. He transitioned to working in the industry with Revlon Health Care as the Head of Quality Assurance Audit Group and the Associate Director of Quality Affairs. Stu later worked with Rorer Group and Rhone-Poulenc Rorer as Associate Director and Director of Regulatory Affairs. After a switch to Sepracor and then Sunovion, he became Senior Vice President, Head of Global Quality Assurance. Retirement really was not for Stu, and he formed SHM Pharma Consulting and kept busy working for several companies, consulting on a wide variety of topics.

Stu was a quick learner and had many great memories of his work and home life. He was able to converse easily on most topics and loved to tell long tales of his travels and work history. He loved an audience, and we all learned from these stories. He was well read, an excellent writer and a crisp thinker. Mentoring was equally as important to him, and he enjoyed working with others to advance their careers. Above all, Stu loved his family dearly and was so grateful for the time spent with all of them during his last few years. He would always do anything he could to support them. He also enjoyed long walks with family and the family dog, Chester.

In lieu of flowers, please consider a gift to the Mass General Cancer Center.

A Celebration of Life gathering will be held at a later date.

I was sorry to hear of Stu's passing today. He was an outstanding person is so many ways and will be missed by all who knew him. We had so many inspiring and enlightening conversations during our time together at Sepracor Inc. His kind and gentle sense of humor was always spot on in helping him make a difficult point or steering a conversation to contemplate an alternative point of view. His leadership and mentorship was often unintentional but so very powerful just the same. He was always an inspiration to do the right thing and he always kept patients first in all that he did. It was one of the greatest pleasures in my career to have had the opportunity to get to know and work with Stu. He was truly a scholar and a gentlemen. My condolences to his family and friends who loved him.

I was the fortunate recipient of Stewart and Deborah's kindness during a difficult time. My most sincere condolences to you and your family, Deborah, and if times allowed, huge hugs--though virtual ones will have to do! I will carry Stewart's kindness and sweet smile in my heart, and I wish your family peace and comfort.

I was sad to hear of Stu's passing. He was a very special person.
A few years after I began at Sepracor/Sunovion, Stu arrived. For the next almost two decades he led my group. I remember fondly working with him on the budget, and I am grateful for his willingness to let me pursue simultaneously work in regulatory information as well as that in budgets and contracts. His wisdom, wit, kindness, and support will long be remembered. With heartfelt sympathy to Deborah, Kathryn, Jon and Sarah -- I know he loved you deeply.

My deepest condolences to the family and friends of Stu. I worked with Stu at Sepracor/Sunovion and truly appreciated his dedication and the depth of his understanding of drug development. We worked together on a large global project, and whenever I had questions regarding the project he always took the time (and patience) to explain his rationale. I was always appreciative of his gentle humor, insight and experience. His memory will stay with me always; may your memories bring you comfort.

I still remember my first day of work at Sepracor and right after the orientation, i was in my cube, about to start my work, and Stu has walked by to introduce himself and check on me if i have everything that i need and if i am comfortable, I was so nervous as this was in a way my first job in Regulatory right out of college, and he made me feel very calm and comfortable. Your kindness, your great smile has always put me at ease. I guess i am one of the very fortunate people to have known you, interacted with you directly and was able to gain knowledge from you. My heartfelt condolences. May you Rest in Peace.

I had the privilege of knowing and working with Stew for many years when he was at Sepracor, then Sunovion, then when he was consulting. He was one of the nicest and smartest men I knew, and someone I looked up to during my entire career. We shared a similar background in that I also grew up in New York. I attended Stuyvesant High School, a staunch "enemy" of Bronx High School of Science, but Stew never held that against me. In our time working together, he was always my advocate, and someone I could turn to for advice at any time. Please accept my heartfelt condolences for your loss.

I am so sorry to hear of Stu's passing. Stu and I worked together at Sepracor/Sunovion for many years. We became fast friends. Always a kind and caring man - I learned a lot from him and am grateful he was in my life. Every year for a Christmas gift, he bought me a Yankee Candle. So thoughtful -
Rest in peace friend. Love to his entire family xo

Like my many former colleagues at Sepracor/Sunovion, Stu is the reason for my career. I applied to be his admin and he said basically that I was too talented to be in the role and suggested that I apply for a position in Regulatory Operations, and I am so glad he did. We all knew that in our quarterly meetings a good amount of time needed to be allotted for Stu’s stories which were always good. Stu was clearly an amazing mentor and an even better person. My condolences to his family and friends, I hope knowing how much of an impact he had on so many life’s is a comfort in this difficult time.

My deepest sympathy to Deborah and family. Stu will be greatly missed by so many of the people he touched, including me. Stu took a chance on me and gave me an opportunity at Sepracor. I often share the story where, initially, as a consultant, Stu asked me to prepare a clinical quality strategy. When I presented it to him, he responded, either you can see if your strategy works or I can give it to someone else who may execute it or not, do you want the job? How could I resist. Stu was the best mentor I ever had. He treated me as a peer and I was honored to sit on his leadership team. I learned from his example. He taught me so many things. When Sepracor was small, we were all like family. We worked through many challenges and heartily celebrated successes. Working for and with Stu and his team was clearly the highlight of my career. Thank you Stu for being a wonderful boss and friend.
