Whose idea was the SOS distress signal?

The SOS distress signal was first proposed by the German government in 1905 and was later adopted at the International Radiotelegraphic Convention in 1906. The signal itself, represented by the Morse Code sequence (··· --- ···), was chosen for its simplicity and ease of recognition. Although commonly thought to stand for "Save Our Ship," it was actually selected because it is easy to transmit and hear, making it effective for emergency situations.
