"Come In" explores how Morse history is entangled with the history of the Spiritualist church. The Spiritualist Church was founded by the Fox sisters in 1850. They claimed that they were mediums who could communicate with the dead and they justified this ability by citing the new ability, through Morse, to speak with someone far away almost instantaneously. After fifty years of practicing Spiritualism, the sisters declared the religion a hoax, and many years later Morse code officially lost its role in the commercial realm. As Spiritualists continue to send messages to the dead in spite of the sisters’ statements, and Morse operators transmit messages into the ether with hope, Johnson asks: How do communication networks and technologies affect our calls and responses and make visible our desire for reciprocity?
