Ed Steward, a noted screw designer and co-founder of extruder-maker American Kuhne Inc. in Ashaway, died on April 9 from a heart attack. He was 61.
Known for his gentle demeanor and sense of humor, Steward won recognition for his innovations in extrusion. He was a member of the Society of Plastics Engineers since 1973, receiving the SPE Extrusion Division's highest honor, the Bruce Maddock Award, in 2004.
Steward also was an SPE fellow.
American Kuhne issued a statement announcing that Steward passed away: Ed's technical contributions as well as his friendship and sense of humor will be greatly missed.
In 1997, Steward co-founded American Kuhne with Bill Kramer. Steward and Kramer left Davis-Standard Corp. to team with Kuhne GmbH, a German maker of single-screw extruders and establish a U.S. operation.
Before starting American Kuhne, Steward was employed at Davis-Standard for 24 years as chief process engineer, responsible for screw design and application engineering.
American Kuhne moved headquarters from Norwich, Conn., to Ashaway in 2008.
Steward earned a bachelor's degree in mechanical engineering from the University of Connecticut. He wrote numerous technical papers on extrusion, including papers on general screw performance, data acquisition for screw design, screw wear, coextrusion, vented extrusion and grooved-feed extrusion.
Steward was a devoted husband to his wife, Rita, and was involved in his church. A sports enthusiast, he liked to play golf and tennis.
Services will be held April 30 at Old Mystic Baptist Church in Mystic, Conn.
