A prolific astronomer with a broad circle of observational interests, and one of the pioneers of modern geodynamics (investigation of the Earth as a planet by means of astronomy, geodesy, and geophysics), Alexander Orlov was also a successful originator of new institutions and a key promoter of Ukrainian astronomy. From his energetic interdisciplinary activities, modern astronomy of the sovereign Ukraine came into its own. Orlov was the founder of an astronomical dynasty and became the most recognized Ukrainian astronomer. He was also head of the multi-personnel school of astronomical research.
Orlov graduated with distinction from Saint Petersburg University in 1902 and in the following years broadened his scientific background by studying at the Sorbonne (France), at Lund (Sweden) with Carl Charlier, and at Göttingen (Germany) with Johann Wiechert. From 1905 to 1913, he worked productively at the Tartu (Estonia)...
