Here is a fresh review on perovskites (thanks for sharing Henrik Pedersen) by ALD from the Group of Prof. Nilsen at Oslo University, which as far as I know are the true masters of creating and understanding complex multi component metal oxides by ALD. I like that the review starts by placing the topic of perovskites in a historical context "In the 90 years since Victor Goldschmidt properly described the perovskite structure in his inaugural paper “Die Gesetze der Krystallochemie”, it has become one of the most studied and iconic classes of materials".
[Wikipedia] Victor Moritz Goldschmidt (Zürich, January 27, 1888 – March 20, 1947, Oslo) was a mineralogist considered (together with Vladimir Vernadsky) to be the founder of modern geochemistry and crystal chemistry, developer of the Goldschmidt Classification of elements. (photo from Wikipedia)

Gustav Rose who discovered the mineral perovskite
The mineral perovskite composed of calcium titanate (CaTiO3) was discovered in the Ural Mountains of Russia by Gustav Rose form The Kindom of Prussia in 1839 and is named after Russian mineralogist Lev Perovski (1792–1856). Amongst others, Gustav Rose studied under famous Swedish physical chemist Jöns Jakob Berzelius (1779–1848) in Stockholm. Berzelius is considered, along with Robert Boyle, John Dalton, and Antoine Lavoisier, to be one of the founders of modern chemistry and introduced chemical notation. [Wikipedia]
