Who made the First EVPs?

Margaret and Ronda of Inspired Ghost Trackers asking questions on digital recorder

According to Wikipedia, "Electronic voice phenomena (EVP) are electronically generated noises that resemble speech, but are supposedly not the result of intentional voice recordings or renderings. Common sources of EVP include static, stray radio transmissions, and background noise. Recordings of EVP are often created from background sound by increasing the gain (i.e. sensitivity) of the recording equipment.
  So, who made the first recordings of ghosts or spirits? According to George Noory's book Talking to the Dead, it was Waldemar Borogas in 1901. He was exiled to Siberia and used a Thomas Edison phonograph during a session he was beating drums. Between the drumbeats he heard disembodied voices!
  Working with the Inspired Ghost Trackers, we've recorded several of them, including one from the Book Escape in Baltimore where we investigated. At the time we got the EVP, I thought I heard a man's voice briefly. When we listened to the digital recording later right after I thought I heard the sound, we all heard "Go away!"
