In this paper a device called a 2-way sequential transducer is defined. Such a device is a natural generalization of the wellknown 1-way sequential transducer, though its behavior is much more complex. Many of the properties of this transducer are derived, and it is shown, for example, that such a transducer maps regular sets and context free languages into the context sensitive languages. The intimate relationship between the class of 1-way stack automata and the 2-way sequential transducer isshown by presenting a new grammar which generates exactly the 1-way stack languages in a perfectly natural way, and it is indicated how several of the properties of 1-way stack languages are obtained from its grammars.
