On November 15, 2010, Leo Esakia died rather unexpectedly in Tbilisi at the age of 76 years. He was one of the important logicians, mainly working in algebraic logic. His name will live on in his Esakia spaces, ordered topological spaces that play a fundamental role in the theory of Heyting Algebras by the Esakia duality between the categories of these spaces and algebras, and in many other theorems and concepts.

By his knowledge, energy and enthousiasm he was a source of inspiration to a large number of students, among which Guram and Nick Bezhanishvili, and David Gabelaia. Through these students he had important connections with the ILLC, and he himself was always involved in the organization of the 2-yearly Tbilisi Symposia in which the ILLC joins the Georgian logicians and linguists. [The last of these Symposia, in 2009, was dedicated to his 75th and Dick de Jongh's 70th birthday.] Leo Esakia was continuously working with his students on new problems, he gave a long lecture to them only last week.
