Fred Tepper
Founder & CEO
Fred Tepper is the genesis and driving force behind all that is Argonide. Born in Brooklyn, N. Y. in 1934 Fred is the consummate inventor and “tinkerer”. He graduated Stuyvesant High, and went on to earn both his B.S. and M.S. in Chemistry from NYU. After short job tenures in New York, including Sylvania-Corning Nuclear Corp, Fred joined the Mine Safety Appliance Co. (“MSA”) in 1957. It was there where he did Research and development on liquid alkali metals including lithium. In 1969 Fred was promoted to manage the Catalyst Research Corporation (“CRC”), a subsidiary of MSA. During his tenure at CRC Fred’s team developed and patented a revolutionary lithium battery that would allow a pacemaker to run ten plus years without recharging. More than 20 million pacemakers have since used this type of battery. In 1984 Fred was promoted to General Manager of MSA’s Instrument Div. in Pittsburgh, and Vice President of MSA. After retirement in 1997 Fred founded Argonide as an investment in nanotechnology. Ultimately, the nanotechnology concentration evolved into an electropositive adsorption material. It was that material that later would become NanoCeram filter Media. Over the years, Fred has been an avid runner and participated in numerous competitive events. Fred, and his wife of over 60 years have two daughters, four grandchildren and four great grandchildren.
