Miguel A. Catalán

Miguel Antonio Catalán Sañudo (1894–1957) was a Spanish spectroscopist. Born in Zaragoza, he obtained his degree in chemistry from the University of Zaragoza and received his doctorate in Madrid in 1917 for his thesis about spectrochemistry. 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.

On the invitation of Arnold Sommerfeld, he worked at the University of Munich, and on the creation by the Rockefeller Foundation of the Institute of Physics and Chemistry (Madrid), in 1930 he was named head of the Spectroscopy Section. He was invited numerous times to work in the laboratories of the National Bureau of Standards (Washington, D.C.), Princeton University, and MIT.

He published more than 70 scientific articles in specialized journals. In 1926, he received a prize from the Real Academia de Ciencias (Spain) and in 1930, the international Pelfort prize.

He married Jimena Menéndez Pidal, the daughter of Royal Spanish Academy director Ramón Menéndez Pidal. Because of the military coup by General Francisco Franco in July 1936, he and his father in law were the subject of numerous misdemeanours.
