Loomis Day | May 30
(Last Updated On: May 23, 2023)


Each year on May 30th, 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 129,971 titled “An Improvement in Telegraphing” on wireless telegraphy in July of 1872 beating Guglielmo Marconi’s United Kingdom patent by nearly 25 years.


Born on July 21, 1826, Loomis was also the inventor of artificial teeth and one of the earliest inventors of wireless communication. Loomis died on October 13, 1886.

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. While he couldn’t explain how he was able to produce the transmission, he appealed to Congress for an appropriation to incorporate the Loomis Aerial Telegraph Company for research. Senator Charles Sumner introduced the bill, and on May 30, 1872, the Committee on Commerce reported poorly on the measure. Stripped of its appropriations, it eventually passed in 1873 strictly as a bill of incorporation.
