• 23．Samuel Morse was born in Massachusetts USA.He started off his career as an inventor after being a painter and sculptor （雕塑家）.He even earned a gold medal from the famous Adelphi Society of Arts for his first effort in sculpture，the "Dying Hercules".He became the first president of the National Academy of Design，and became Professor of the Arts of Design in the University of the City of New York.
     Yet，this painter turned to inventing to make his fortune during a sea voyage.On this journey，Samuel Morse heard about many attempts to create usable telegraphs.He was fascinated by this problem and began to study books on physics for two years to gain more scientific knowledge.He realized that pulses （脈沖） of electrical current could carry information over wires.
     Thus the world's first working model of a telegraph was born.His signaling device was quite simple.It consisted of a transmitter （containing a battery and a key），a small buzzer （蜂鳴器） as a receiver and a pair of wires connecting the two.Samuel Morse improved it by adding a switch and a second buzzer to allow transmission （傳播） in the opposite direction as well.
     On May 24，1844 Samuel Morse sent the first electronic message between Baltimore and Washington，"Look what God has enabled us to build，and benefit by."
     Seventeen years later，the two coasts of the United States were linked by telegraph.The telegraph continued to enjoy the position of being the fastest and most reliable means of communication for almost 140 years since its invention.
