Alexander Graham Bell, the inventor of the telephone was born in Edinburgh, Scotland on March 3, 1847. He emigrated to Canada in 1870 and later settled down in the United States of America. While he was devoting himself to the tranining of teachers of the deaf as a vocal physiologist, he was interested in the transmission of sound by electricity and invented as a result of his studies an apparatus that became the forerunner of the modern telephone.

In Korea, the telephone was first installed in 1898 and the number of telephone subscribers has steadily increased and now crossed the one million mark.
