In 1970, Al Varrieur sat at his kitchen table wondering how to protect his family's small commercial greenhouse operation from the ravages of New Hampshire's frosty seasons. A retired executive and aeronautical engineer, Al used his skills to develop a temperature-alarm instrument that was reliable, simple to operate and inexpensive to manufacture. His first Thermalarm filled a need in the market that no other design had.
