Who was Pierre Curie?
Pierre Curie (1859–1906) was a French physical chemist and a key figure in modern physics. With his wife, Marie Curie, he won the 1903 Nobel Prize in Physics for their research into radioactivity and the discovery of radium and polonium.
Curie's early work involved studies of crystals with his brother Jacques, leading to their discovery of piezoelectricity. Later, his research on magnetism led to Curie's law, defining the relationship between temperature and paramagnetism.
After marrying Marie Skłodowska, the pair investigated radioactivity, leading to the discovery of polonium and radium in 1898. Pierre studied the physical properties of the new radiations, proving the existence of positive, negative, and neutral particles, later known as alpha, beta, and gamma rays.

What is radioactivity and how did Pierre Curie help discover it?
Radioactivity is the property of specific matter types to spontaneously emit energy and subatomic particles. It is an attribute of individual atomic nuclei.
Pierre Curie and his wife Marie Curie investigated radioactivity, leading to their discovery of radium and polonium in 1898. Pierre primarily studied the physical properties of new radiations, while Marie focused on extracting pure substances. Through magnetic fields on radium emissions, Pierre proved the existence of positive, negative, and neutral particles, later known as alpha, beta, and gamma rays. In 1903, the couple, along with Henri Becquerel, were awarded the Nobel Prize in Physics for their work on radioactivity.

Pierre Curie (born May 15, 1859, Paris, France—died April 19, 1906, Paris) was a French physical chemist, cowinner with his wife Marie Curie of the Nobel Prize for Physics in 1903. He and Marie discovered radium and polonium in their investigation of radioactivity. An exceptional physicist, he was one of the main founders of modern physics.

Educated by his father, a doctor, Curie developed a passion for mathematics at the age of 14 and showed a particular aptitude for spatial geometry, which was later to help him in his work on crystallography. Matriculating at the age of 16 and obtaining his licence ès sciences at 18, he was in 1878 taken on as laboratory assistant at the Sorbonne. There Curie carried out his first work on the calculation of the wavelength of heat waves. This was followed by very important studies on crystals, in which he was helped by his elder brother Jacques. The problem of the distribution of crystalline matter according to the laws of symmetry was to become one of his major preoccupations. The Curie brothers associated the phenomenon of pyroelectricity with a change in the volume of the crystal in which it appears, and thus they arrived at the discovery of piezoelectricity. Later Pierre formulated the principle of symmetry, which states the impossibility of bringing about a specific physical process in an environment lacking a certain minimal dissymmetry characteristic of the process. Further, this dissymmetry cannot be found in the effect if it is not preexistent in the cause. He went on to define the symmetry of different physical phenomena.
Appointed supervisor (1882) at the School of Physics and Industrial Chemistry at Paris, Curie resumed his own research and managed to perfect the analytical balance by creating an aperiodic balance with direct reading of the last weights. Then he began his celebrated studies on magnetism. He undertook to write a doctoral thesis with the aim of discovering if there exist any transitions between the three types of magnetism: ferromagnetism, paramagnetism, and diamagnetism. In order to measure the magnetic coefficients, he constructed a torsion balance that measured 0.01 mg, which is still used and called the Curie balance. He discovered that the magnetic coefficients of attraction of paramagnetic bodies vary in inverse proportion to the absolute temperature—Curie’s law. He then established an analogy between paramagnetic bodies and perfect gases and, as a result of this, between ferromagnetic bodies and condensed fluids.
The totally different character of paramagnetism and diamagnetism demonstrated by Curie was later explained theoretically by Paul Langevin. In 1895 Curie defended his thesis on magnetism and obtained a doctorate of science.
In the spring of 1894 Curie met Marie Skłodowska, and their marriage (July 25, 1895) marked the beginning of a world-famous scientific achievement, beginning with the discovery (1898) of polonium and then of radium. The phenomenon of radioactivity, discovered (1896) by Henri Becquerel, had attracted Marie Curie’s attention, and she and Pierre determined to study a mineral, pitchblende, the specific activity of which is superior to that of pure uranium. While working with Marie to extract pure substances from ores, an undertaking that really required industrial resources but that they achieved in relatively primitive conditions, Pierre himself concentrated on the physical study (including luminous and chemical effects) of the new radiations. Through the action of magnetic fields on the rays given out by the radium, he proved the existence of particles electrically positive, negative, and neutral; these Ernest Rutherford was afterward to call alpha, beta, and gamma rays. Pierre then studied these radiations by calorimetry and also observed the physiological effects of radium, thus opening the way to radium therapy.
Refusing a chair at the University of Geneva in order to continue his joint work with Marie, Pierre Curie was appointed lecturer (1900) and professor (1904) at the Sorbonne. He was elected to the Academy of Sciences (1905), having in 1903 jointly with Marie received the Royal Society’s Davy Medal and jointly with her and Becquerel the Nobel Prize for Physics. He was run over by a dray in the rue Dauphine in Paris in 1906 and died instantly. His complete works were published in 1908. Pierre and Marie’s daughter, Irène Joliot-Curie (born 1897), won the 1935 Nobel Prize for Chemistry with her husband, Frédèric Joliot-Curie.
