Dutch geologist from a noted family. Lamoraal Ulbo de Sitter was born in a family of jurists. But he, his father Willem and brother Aernout were more interested in the exact sciences. As his father Willem de Sitter (and brother) already studied cosmology, Lamoraal Ulbo decided to study the Earth. His son Ulbo would become a noted sociologist, having as slogan "Kennis moet genomen worden" (Knowledge must be taken USK). He dissertated in 1925 in Leiden with "Les porphyres luganais entre le lac de Lugano et le Valganna", From 19 November 1948 till 19 February 1964 he was professor of geology in Leiden. His book Structural Geology (1956) became a classic. He died 12 May 1980 in Nistelrode. Link to Wikipedia
