Abstract :
Mr. Watson was stationed in one room with the receiving instrument. He pressed his ear closely against S [the receiving instrument] and closed his other ear with his hand. The transmitting instrument was placed in another room and the doors of both rooms were closed. I [Graham Bell] then shouted into M [the horn of the transmitting instrument] the following sentence: ¿Mr. Watson-Come here-I want to see you.¿ The story of the invention of the telephone is a fascinating one: it contains romance; a rise from poverty to riches; royal occasions; a race between inventors; the defeat of a giant corporation by the small man; and success brought about by a combination of genius, hard work and happy coincidences
