TWO GENERATIONS1
OF THE CURIES2
More than 100 years have passed since the birth of Marie SklodowskaCurie
(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
famous scientist, but also a famous leader of the progressive movement for
human rights.
The two generations of the Curies devoted their lives to science. Pierre
Curie, famous for his discoveries in magnetism, provided an example of deep
dedication6
to research. Marie, her daughter Irene and Irene's husband Frederic
all died from radiation sickness, the result of long years of work with radioactive
substances.
There is no parallel in the records of science to the dynasty of the Curies.
