Maria Skłodowska-Curie – born in 1867 in Warsaw, died in 1934 in Sancellemoz (France)

She graduated from the Paris University of Sorbonne, from 1906 she was a lecturer and professor of this University. In July 1898, in cooperation with her husband Pierre Curie, by fractional crystallization of pitchblende (uranium ore waste) she obtained a fraction containing an increased amount of the first radioactive element, which they named polonium.  In December the same year she obtained a chloride of another element, even stronger radioactive, named radium, which was a main admixture in barium chloride isolated from pitchblende. In 1903 the Curie couple, together with Antoine Henri Becquerel, obtained a Nobel Prize in physics. In 1902 they succeeded in isolating pure radium chloride. For this achievement, Maria Skłodowska-Curie obtained in 1911 another Nobel Prize, in chemistry. Maria Skłodowska-Curie developed the knowledge of radioactivity; she supported foundation of the Radium Institutes in Paris (1914) and in Warsaw (1932) which she headed. She was among the founders of Polish Chemical Society (in 1919). In 1924 she was made an honorary member of PCS. In 1995 the ashes of Maria Skłodowska-Curie were moved to the Paris Pantheon. The Parliament of the Republic of Poland devoted the year 2011 to honour Maria Skłodowska-Curie.

Jan Czochralski – born in 1885 in Kcynia, died in 1953 in Poznań

Jan Czochralski studied at the Charlottenburg Polytechnics, near Berlin, from which he graduated as an engineer of chemistry in 1910. For four years he worked at this Polytechnics in the group of Wichard von Moellndorff with whom he wrote his first paper on crystallography of metals in which he described the fundamentals of the theory of dislocations. Many of his papers were devoted to metallography, in particular the application of aluminium in electronics. He won worldwide renown for the method of control of metal crystallization rate, discovered in 1916, which in 1954 was used for production of silicon monocrystals and the first ever silicon transistor. This method, known today as the Czochralski method, has become fundamental for production of printed circuits. Jan Czochralski also discovered the tin-free alloy (known as metal B) used for production of sliding bearings, commonly used until the 1960s. He is the most frequently cited Polish scientist. After clarification of many years of confusion regarding his behaviour during the World War II, he won general recognition of scientific circles and the deserved position among Polish scientists.
