It is shown that T duality in the string theory is related to the separation of variables procedure in dynamical system. We argue that there are analogues of S duality as well as 3d mirror symmetry in the many-body systems of Hitchin type governing low-energy effective actions.16 pages, Latex, Talk given at QFTHEP-99, Moscow, May 27-June 2High Energy Physics - Theorytext
