Thomas Stewart Obituary
Tom earned a Bachelor of Science degree from the Heriot-Watt University, a PhD in Chemistry degree from the University of Glasgow and then did two post doctorate research assignments; the first at the California Institute of Technology and the second at the University of Glasgow. In 1968 he began his career with Rohm and Haas in Tudela, Spain, later relocating to Philadelphia, Pennsylvania where he met and married his wife, Maureen McGrory Stewart of 39 years whom he loved dearly. Tom dedicated 36 years to supporting research and development, holding various roles of increasing responsibility within Rohm and Haas until his retirement in 2004 as the Global Technology Director of the Plastic Additives Business and authoring many patents as inventor or co-inventor.
Outside of his professional life, Tom enjoyed White Water Paddling, Downhill Skiing, Hiking, Travel, Wood-working, and Golf. He was known for his adventurous spirit and love for the outdoors.
Tom is survived by his daughter and son-in-law, Shiona Stewart and Christopher Mucha, partner Arlene Caney, first wife Marcia Hudson, nephews Brian Kelly, John McGrory, James McGrory and Matthew McGrory, nieces Susan O'Reily, Susan Turbitt, Kimberly McGrory Butler, Shannon McGrory, Sheila McGrory Sweeney, and Maureen Heather Lisowski, and many loving great nieces and nephews.

Hard to believe it has been a year. I think about Tom often and the good times we had. He is sorely missed

Tom was one of the brightest and most creative person I have ever known. I was fortunate enough to work closely with him at both Rohm and Haas and Polysciences. I considered him a very close and supportive friend. I will never forget him.

Tom and I have been close friends for over 40 years and shared many adventures together. The following highlights some of them:
I first met Tom kayaking on the Nescopeck Stream in the early 1980´s (it was in flood and I think both of us "swam"). We became friends and paddled many whitewater streams with the Wilmington Trail Club and the splinter group "39ish paddlers" over the next 35+ years. Tom and I kayaked the Grand Canyon with our wives on the support raft. Kayaking trips on southern and western rivers, Ecuador, Costa Rica, and Canada followed over the years. I became dependent on Tom´s skill to get me out of trouble and provide entertainment to the group both on and off the rivers. Tom was an excellent paddler and a joy to be with.
Tom and his wife Maureen introduced me to skiing in the 2000´s. Tom and I skied the East Coast and out west (Salt Lake are mostly) Tom was helpful in critiquing my skiing ("you really screwed that run up") and we enjoyed skiing together.
Tom, Ted and I hiked together many times over the last 15 years and enjoyed our discussions during the hikes. Tom and I went to Scotland about 8 years ago to hike on the Isle of Sky and then a week in Edinburgh where I met his long time Scottish Friends.
I will truly miss him
