May 30. To honor Mahlon Loomis, a Washington, DC, dentist who received a US patent on wireless telegraphy in 1872 (before Marconi was born). Titled An Improvement in Telegraphing, the patent described how to do without wires; this patent was backed up by experiment on the Massanutten Mountains of Virginia.
