EUROPA94 - Discoveries - Spain 5.5.1994
Severo Ochoa de Albornoz, Spanish - American Doctor of Medicine and Biochemist, and joint winner of the 1959 Nobel Prize in Physiology or Medicine with Arthur Kornberg. A new research center that was planned in the 1970s, was finally built and named after Ochoa. The asteroid 117435 Severochoa is also named in his honour.
Miguel Antonio Catalán Sañudo (1894–1957) Spanish spectroscopist. The lunar crater Catalán is named after him. Born in Zaragoza, he obtained his degree in chemistry from the University of Zaragoza and received in doctorate in Madrid in 1917. In 1920, he began work as a researcher at Imperial College London. Examining the spectrum of the arc of manganese, he determined that the optical spectra of complex atoms consisted of groups of lines –which he called "multipletes"- between which existed certain characteristic regularities. Catalán demonstrated that study of the multipletes led to further understanding of the states of energy of atomic electrons.
