In the 1980s, Everest Interscience, Inc. introduced infrared temperature-measurement products.  Everest Interscience, Inc. was co-founded by Charles E. "Gene" Everest.

Mr. Everest possesses more than thirty years of continuous career efforts of designing electro-optical instruments, the last twenty-two years of which have been spent specializing in the design of infrared surface temperature measurement thermometers and sensors. 

Subsequent to earning his BSEE from MIT in 1957, he joined Bell and Howell Corporation in Pasadena, California, designing electro-optical recording oscillographs.  After working at the Bell and Howell Research Center in Pasadena and Rockwell International  Microelectronics in Anaheim, California, Mr. Everest became a consultant in his chosen field in 1969.  He designed Wahl Corporation's line of infrared thermometers in the early 1970s, including the world's first digital handheld infrared thermometer in 1973.  In the mid-1970s, he designed Telatemp Corporation's line of infrared thermometers.

His third generation and subsequent generations have been designed for Everest over the last twenty-two years.  In that time, he has been a guest lecturer in Australia, China, Canada, Italy, and at various technical meetings and universities in the United States.
