Joe Fischer – EMC Pioneer

From Ocean Lifeguard to Antenna Designer to EMC Engineer

In his teens and early 20’s Joe was a lifeguard in San Diego, equipped with the tools of a whistle and “can” saving soused sailors, shouting at surfers and soothing the nerves of “lost” mothers.

In 1961, while working for Genistron, Joe spent a summer in Greece investigating spectrum utilization for N.A.T.O.

Several attempts at a new high power bulk current injection probe resulted in Virginia getting a new kitchen and Joe moving into a 500 square foot facility.

By the early 1980’s, Joe and Virginia had a workforce of 20 and mounted their first FCC orange bolt over the doorway of a 1,000 square foot building.

Today they have over 30 employees manufacturing 500 different products within a 20,000 square foot building, selling to 24 foreign countries and several hundred U.S. private enterprise and government companies.

55 years of innovative EMC test and measurement equipment development coupled with 70 years of marriage.
