Born in La Crosse, WI in 1933 of Finnish parents, Stuart, with five other fellow scouts, achieved the rank of Eagle Scout in 1950. After obtaining a chemical engineering degree from Wisconsin and marrying his high school sweetheart Sally, he joined the E. I. DuPont de Nemours Co. Inc. Stuart and Sally were married for 49 years and his family always came first.

Shortly after joining DuPont, he joined the U.S. Army and served studying ballistics. Stuart returned to DuPont and remained for 44 years in research, sales, plant engineering, and technical service. In the field of Teflon® FEP resins he developed a dispersion resin, a stress crack resin, and a multitude of foam resins. He also developed many foam processes for FEP resin. In the field of Teflon® PTFE resin, he identified the key DuPont plant process variable for producing a resin for porous materials (Goretex®). In polymer rheology, Stuart discovered how to eliminate surface roughness in the production of molten FEP articles. The phenomenon is called The Randa Effect. His numerous patents will continue to serve the company well into the 21st Century. Stuart was elected to his high school Hall of Fame in 1991. Stuart retired from DuPont in 1999 as senior Technical Consultant and began consulting with Saint-Gobain Advanced Ceramics on rheology applications. In 2004, Stuart received the Charles D. Scott award for devoted technical service to DuPont’s customers. Stuart was an active member of the Lutheran Church of the Good Shepherd, the NRA, and the Finnish Groups in the area and the National Society of Plastics Engineers. Stuart enjoyed many recreational activities. His interest in genealogy inspired him to write two books on family history. Stuart also wrote a book on statistics, entitled The Weibull Distribution Function. After retiring from consulting he restored his 1977 Chevy Blazer and made eight violins. He wrote a book on violin making, entitled Creating the Perfect Violin.

Stuart was extremely proud of the academic achievements of his three children, Sonja Apsley (Wayne) of Wilmington, DE, Laura Randa (Brian Doan) of Rye, NY, and Eric Randa (Stephanie Finanger) of Nashville, TN. He continued by setting high standards for his six grandchildren, Autumn (22) and Adam (20) Apsley of Wilmington, DE, Lauren (14) and Christopher (14) King of Rye, NY, and Erica (31) and Stephen (27) Randa of Nashville, TN. He is also survived by his brother Gerald. His wife, Sally, preceded him in death in 2005.
