Abstract: | We develop the notion of Jordan bialgebras and study the way in which such are related to Lie bialgebras. In particular, it
is shown that if a Lie algebra L(J) obtained from a Jordan algebra J by applying the Kantor-Koecher-Tits construction admits
the structure of a Lie bialgebra, under some natural constraints, then, J permits the structure of a Jordan algebra.
