What did Wilhelm Hormann conceptualize in Germany, termed "home alert"?
Answer
Hausnotruf
Wilhelm Hormann, working in Germany during the early 1970s, was developing a framework for ambulatory and non-ambulatory care that he specifically termed *Hausnotruf*, which translates to "home alert." While his initial intent was rooted in creating a method to record and share data with biomedical field scientists, the underlying structure formed a significant philosophical groundwork for what would later become Personal Emergency Response Systems (PERS). This early conceptual work preceded the consumer implementation focused purely on personal safety signals.
