                  THE INVENTION OF THE TELEGRAPH

       The first practical telegraph was invented by the famous English scientist
Charles Wheatstone in 1837. His telegraph was used in England for several
years. But the telegraph invented by the American inventor Samuel Morse was
more successful. Morse began working on his model in 1832, the same year as
Wheatstone, and completed it in 1837. He proposed to put it in use in the United
States. The first experimental telegraph line between Washington and Baltimore
was built is 1844.
       Many improvements have been made on the Morse telegraph, including
one by Thomas Edison, who invented the method of sending four messages over
the same line at the same time.

                  TWO GENERATIONS1 OF THE CURIES2

       More than 100 years have passed since the birth of Marie Sklodowska-
Curie (l867-l934), an outstanding Polish scientist, whose discoveries in physics
and chemistry began the era of the utilization of atomic energy.
       Marie lived to see her story repeated. Her daughter Irene grew into a
woman with the same interests as her mother's and she was deeply interested in
her mother's work. From Marie she learned all about radiology, about opened by
her mother element radium and chose science for her career. At twenty-nine
Irene married Frederic Joliot, a brilliant scientist at the Institute of Radium,
which her parents, Marie and Pierre had founded.
       Frederic Joliot was born in Paris in 1900. He first studied engineering and
then chemistry. Together the Joliot-Curies carried on the research work that
Irene's mother had begun. In 1935 Irene and her husband won the Nobel Prize
for their discovery of artificial3 radioactivity.
       So, Marie lived to see the completion4 of the great work, but she died on
the eve5 of the award.
       In 1946 Joliot was appointed scientific adviser to the International Atomic
Energy Commission of the United Nations. Frederic Joliot-Curie was not only a
