Papers of Zdenek Kopal

Archive Collection

Scope and Content

The papers include a very large quantity of correspondence, including letters from fellow astronomers in the United States and the Soviet Union, early lunar charts and glass-plate photographs of the moon, numerous drafts of papers by Kopal, and a large collection of offprints and copies of articles by other scientists on satellite programmes, lunar exploration, and co-operation between British, American and Russian astronomers.

Administrative / Biographical History

Zdenek Kopal, professor of astronomy at Manchester University from 1951-1981, was born on 4 April 1914 at Litomysl in eastern Bohemia (now the Czech Republic). His interest in astronomy developed during adolescence (he published his first paper at the age of sixteen), with a particular interest in optical telescopes. As a professional astronomer he first made his name with the study of close binary stars and the development of the numerical methods required to investigate their nature through the variation in their brightness. He began his academic career at Prague, followed by a short period at Cambridge, before moving to the USA where he taught at Harvard and the Massachusetts Institute of Technology during and after the Second World War. During this period, he became an American citizen and used his mathematical skills for the benefit of the US Army during the War.

In 1951 he moved to Manchester to take up the new Chair of Astronomy, and in the succeeding years he built up an international reputation for the department. At Manchester he undertook path-breaking work on the transfer of mass between separate stars in a binary system; this phenomenon remains the key to understanding many modern, often space-made, observations of violently eruptive behaviour in the stellar system. The numerical methods required for his astronomical analysis, were described in 1955 in a classic work, Numerical Analysis , which is still in use.

Around this time Kopal developed a great interest in lunar studies, and switched his energies to studying the moon. He assembled a group to take over 100,000 photos of its surface using an ancient 2 ft diameter refracting telescope of L'Observatoire du Pic du Midi in the south of France, which was renowned for its good 'seeing' capabilities. The telescope had a sufficiently long focal length of 60 ft to produce images suitable for lunar mapping. Given the great American interest in this subject, USAF provided Kopal with a great deal of money to systematically map the moon; this proved vitally important when the Apollo landings were undertaken. The project gave considerable prestige and funds to the Manchester department, and Kopal was much in demand all round the world as a space consultant. After his lunar work was completed Kopal went back to the study of binary stars. He also helped develop the subject of astronomy in the Middle East, training a number of astronomers from Egypt, Libya, Iraq and Iran. He is credited with producing 396 papers on optical astronomy. Kopal was known as a charming, highly intelligent, eccentric scientist. He married in 1938 and had three daughters. Kopal died in June 1993.
