Loomis Day

Mahlon Loomis (1826 to 1886) practiced dentistry in Washington, D.C., where he also invented artificial teeth. But his imagination reached far beyond the dental chair. As early as 1864 he sketched a complete system for wireless signaling: a tall aerial wire, a keying device, and a receiver, all connected to the ground, designed to disturb the electrical balance of the atmosphere and carry a signal to a distant station.

In October 1866 he put the idea to the test in Virginia's Blue Ridge Mountains. From the summit of Bear's Den Mountain, Loomis flew a kite carrying 600 feet of copper wire partially covered in copper mesh. Twenty-one miles away at Furnace Mountain near Point of Rocks, a second kite carried a crude galvanometer. When Loomis worked his key, the needle on the distant instrument moved, again and again: a repeatable wireless signal sent years before scientists understood the electromagnetic waves carrying it.

Loomis patented his system on July 30, 1872, receiving U.S. Patent 129,971 for an ‘Improvement in Telegraphing.’ He demonstrated his apparatus before scientists and members of Congress in 1868, and Senator Charles Sumner introduced a bill to incorporate the Loomis Aerial Telegraph Company. Congress never funded it, and Loomis died in 1886 without seeing his vision realized. Yet his kites over the Blue Ridge remain one of the first documented wireless transmissions in history.

Loomis Day invites communities to remember that breakthrough ideas often come from outsiders. A dentist with kites and copper wire imagined a world connected without cables, and though the world took decades to catch up, his curiosity helped point the way.
