Thomas worked for the   National Bureau of Standards in Boulder (with a couple of brief stints in Gaithersburg, MD) as a Cryogenic Engineer for 28 years.  He left there and went to work for Ball Aerospace.  He is the founder of the cryogenic consulting firm, Cryoco, Inc. (Louisville, CO).  He is a past president of the National Cryogenic Engineering Association and is the author of more than 50 professional publications on topics related to cryogenic engineering. Thomas developed a cryogenic engineering short course and a cryogenic safety course.  He authored the Cryogenic Engineering handbook (1st and 2nd editions), co-authored a Cryogenic text book, and was regarded as one of the world’s foremost experts on cryogenic engineering.  He was also a Professor Adjunct at CU, Boulder; he also taught at the Colorado school of Mines, and did some teaching for the UCLA extension. 

He loved to travel.  He frequently took his wife and kids to the Desert Southwest of the US (AZ, NM, & UT), to the Grand Mesa of CO, and to the Outer Banks of NC.  Thomas took up SCUBA diving and became a Dive Master.  That hobby took him to some of the warmer climates of Mexico, the Caribbean, Egypt, Thailand, and Indonesia.  Thomas’ career took him to, England, Ireland, Germany, many other countries in Europe, and China, often with his wife who loved travel as much, if not more, than he did.  His other hobbies have included: skiing, fishing, gardening, wild mushroom hunting (he served as President of the Colorado Mycological Society), and G scale model railroading to name a few.

Thomas was preceded in death by both of his parents, his brother (Bernard Michael, Jr.), and his loving wife of 48 years; Rita.  He is survived by his son Timothy Flynn, daughter Mary Robinson, son-in-law Jay Robinson, daughter Eileen Flynn, son Thomas Flynn, daughter-in-law Kimberly, and two grandchildren (Sean Flynn and Sara Robinson).
