Morse Code

Samuel Morse was born on 17 April 1791

Why is Samuel Morse famous?

Samuel Morse invented Morse code. He translated every letter of the alphabet into a combination of dots and dashes which he then used to transmit messages over electrical wires.

Morse Code can be transmitted using sound or light, as sometimes happens between ships at sea. The long sounds/lights are dashes, while the short sounds/lights are dots.

Distress Signal

Probably the most well known Morse Code Message is the one made up of three short pulses, then three long pulses, then three short pulses again.

"dot dot dot, dash dash dash, dot dot dot."

This message means "S O S" (S = "..." and O is "---"), the distress signal - save our souls.
