Struger in 1958–60 at the Allen-Bradley company in Milwaukee, WI, USA. A programmable logic controller, or PLC, is a simple electronic device that allows precise numerical control of machinery. It is widely used to control everything from washing machines to roller coaster to automated manufacturing equipment.''</ref> and is credited with coining the PLC acronym.<ref name=":1" /><ref name=":2" /> Allen-Bradley (now a brand owned by [[Rockwell Automation]]) became a major PLC manufacturer in the United States during his tenure.<ref name="short2">{{cite web |url=http://www.jimpinto.com/writings/automationhistory.html |title=A Short History of Automation Growth |access-date=2008-06-20 }}</ref> Struger played a leadership role in developing [[IEC 61131-3]] PLC programming language standards.<ref name=":1" />
