In a nutshell

Xavier Le Pichon (French pronunciation: ; 18 June 1937 – 22 March 2025) was a French geophysicist. Among many other contributions, he was known for his comprehensive model of plate tectonics (1968), helping create the field of plate tectonics. In 1968, he combined the kinematic ideas of W. J. Morgan, D. McKenzie and R. L. Parker with the large data sets collected by Lamont, and especially with the respective magnetic profiles, show that Plate Tectonics could accurately describe the evolution of the major ocean basins. He was a professor at the Collège de France, holder of the Chair of Geodynamics (1986–2008). He was a lifelong fervent Catholic and came to think of caring attention to others' weaknesses as an essential quality that allowed humanity to evolve. He lived with his wife and had six children and eleven grandchildren. He died in Sisteron on 22 March 2025, at the age of 87.
