Which company introduced the first medical alert necklace tied to a landline in 1975?

Answer

American International Telephone Company

In 1975, the American International Telephone Company made a significant move into marketable alert technology by releasing an emergency home phone system. This system was distinct because it incorporated a wearable medallion. When activated by pressing the button, this medallion broadcast a pre-programmed message to multiple predetermined phone numbers. This functionality established it as the first true medical alert necklace that was directly integrated and tied to a traditional landline telephone infrastructure.
