Loomis Day recognizes the man who received the patent for wireless telegraphy in 1872. The Washington, D.C. dentist, Mahlon Loomis, received US patent number 129,971titled “An Improvement in Telegraphing” on wireless telegraphy in July of 1872 beating Guglielmo Marconi's United Kingdom patent by nearly 25 years. Leading up to his patent, Loomis conducted many experiments in electricity using kites flying miles apart in the mountains of Virginia. Then in 1868 before several scientists and Congressmen, he demonstrated his wireless telegraphic system.
