Considered one of the founding fathers of the modern American suppressor industry, Dr. Philip H. Dater, MD, has quietly passed. 

The New York-born Dater, a radiologist and Vietnam-era U.S. Air Force veteran, started designing suppressors in the 1950s, later "dabbling off-hours in his hospital's machine shop." He founded Automatic Weapons Company, or AWC, in Albuquerque, New Mexico, in the mid-1970s to pursue his designs before leaving to co-found Gemini Technologies, now Gemtech, in the 1990s.  

As noted by Gemtech, "Dr. Dater merged his passion for guns and his knowledge of ultrasound to create solutions that would silence skeptics and improve the overall shooting experience."

Even after stepping away from manufacturing suppressors, Dater penned numerous technical papers in firearms journals and magazines. He continued to patent new designs, consult with industry partners, and hold classes on suppressor history and development well into his 80s. 

The trade group for the American suppressor industry mourned his passing. 

"I had the distinct privilege of working for Phil for nearly 11 years at Gemtech before coming to the American Suppressor Association," said ASA Vice President Owen Miller in an email to Guns.com. "He was an incredible mentor who had a profound impact on my career development within the industry. More importantly, he was a great friend, and he will be truly missed."

Dater's death was first noted by JK Armament last week, who described him as "the most influential innovator in the world of firearm silencers since Maxim."

If you have a few, sit in on Jk's interview with Dr. Dater last year. It is worth your time.
