First Steam Fog Horn

FIRST STEAM FOG HORN

In 1854, Robert Foulis of St. John, N.B., first advocated the
use of a steam horn or whistle to give warning to vessels in
foggy weather. An apparatus devised by him was installed on
Partridge Island in 1859. This was the first steam fog horn
ever constructed or operated in the world.
