e and fire-alarm telegraph.
At the same time he suggested a practical form of military telegraph.

In 1842, he laid the first subaqueous cable.

In 1842, he discovered, with Dr. Fisher, the principle of duplex
telegraphy, and he was also the first to experiment with wireless
telegraphy.

In addition to his electrical inventions and discoveries he was the first
to experiment with the Daguerreotype in America, and, with Professor
Draper, was the first in the world to take portraits by this means,
Daguerre himself not thinking it possible.

The verdict of the world, as pronounced at the time of his death, has
been strengthened with the lapse of years. He was one of the first to be
immortalized in the Hall of Fame. His name, like those of Volta, Galvani,
Ampere, and others, has been incorporated into everyday speech, and is
now used to symbolize the language of that simple but marvellous
invention which brings the whole world into intimate touch.
