Ivo M. Babuška (22 March 1926 – 12 April 2023) was a Czech-American mathematician, noted for his studies of the finite element method and the proof of the Babuška–Lax–Milgram theorem in partial differential equations.

[3] He studied civil engineering at the Czech Technical University in Prague, where he received the Dipl.

From 1949 he studied at Mathematical Institute of the Czechoslovak Academy of Sciences and then was the head of the Department of Partial Differential Equations.

[3][4] Babuška fled Communist Czechoslovakia in 1968 with barely more than he could carry, following a conference in Western Europe, and emigrated to the United States.

He was an invited speaker at many major international conferences and a member of numerous editorial boards for scientific journals.

[3] In 2005, Babuska was awarded the Honorary Medal "De Scientia Et Humanitate Optime Meritis", received the ICAM Congress Medal (Newton Gauss, 2016) and he was elected to the National Academy of Engineering.
