Bernard C. Morin (born March 3, 1931 in Shanghai - † March 12, 2018 ) was a French mathematician who dealt with topology .

Morin went blind at the age of 6, but nevertheless embarked on a successful career as a mathematician. He was a professor at the University of Strasbourg . From 1966 to 1968 he was at the Institute for Advanced Study .

Stephen Smale had shown in 1959 that the "eversion" of the 2- sphere , i. H. a regular homotopy in 3- dimensional space , which turns the inside of a sphere outwards (and avoids any folds and cracks), was possible. Morin, Anthony Phillips and Arnold Shapiro found an explicit construction . Morin's version was also portrayed in a 1977 computer-animated film directed by Nelson Max.
