First discoveries

In 1880 he discovered piezoelectricity with his brother Jacques , that is, the phenomenon by which when compressing a crystal (quartz) an electric potential is generated . Later both brothers demonstrated the opposite effect: that crystals can deform when subjected to a potential.

In 1894 he enunciated the universal principle of symmetry : the symmetries present in the causes of a physical phenomenon are also found in its consequences.

During his doctorate and the following years he devoted himself to researching around Magnetism . He developed a very sensitive torsion balance to study magnetic phenomena and studied ferromagnetism, paramagnetism and diamagnetism. As a result of these studies, the discovery of the effect of temperature on paramagnetism, currently known as Curie’s Law, stands out . He also discovered that ferromagnetic substances have a temperature above which they lose their ferromagnetic character; this temperature is known as the temperature or Curie Point .

Works with Marie Curie

In 1895 he married Marie Sklodowska ( Marie Curie ), the daughter of two Polish teachers, with whom he developed an important part of his research. From that moment they dedicated themselves together to the study of the then novel field of Radioactivity and worked on the isolation of Polonium and radium .

He was awarded the Nobel Prize in Physics with his wife Marie Curie in 1903 , in recognition of the extraordinary services they jointly provided in their research on radiation discovered by Professor Henri Becquerel .

Both were also awarded the Davy Medal from the Royal Society of London in 1903.


He died in an accident the morning of the 19 of April of 1906 , to being run over by a horse on a street in Paris on his way to his lab.

With Marie Curie he conceived Irène Joliot-Curie who, together with her husband Frédéric Joliot-Curie , would continue the work of Pierre and Marie and would win, also with him, in 1935 the Nobel Prize in Chemistry . The 21 of April of 1995 the remains of Pierre Curie moved from the family vault at the Pantheon in Paris .


In 1910, the Congress of Radiology approved the name curium for the unit of radioactive activity (3.7 × 10 10 disintegrations per second).

In his honor, as well as that of his wife, the Asteroid (7000) Curie , discovered on November 6 , 1939 by Fernand Rigaux , is named . The synthetic element Curium (Cm) discovered in 1944 was also named in his honor , as well as the Curie crater on the Moon and the Curie crater on Mars .
