      Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first

person to win it twice. However, few people know that she was also the mother of a Nobel Prize

winner.

     Born in September, 1897, Irene Curie was the first of the Curies' two daughters. Along with nine

other children whose parents were also famous scholars, Irene studied in their own school, and her

mother was one of the teachers. She finished her high school education at the College of S?vign? in

Paris.

     Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics.

When World War I began, Irene went to help her mother, who was using X-ray facilities (设备) to

help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in

military hospitals in France and Belgium. Her services were recognised in the form of a Military's

Medal by the French government.  

     In 1918, Irene became her mother's assistant at the Curie Institute. In December 1924, Frederic

Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in

 love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five

years later.

     Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel

Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia

because of her work with radioactivity(辐射能). Irene Joliot-Curie died from leukemia on March 17,

1956.(www.yygrammar.com)
