We propose that the ten-dimensional E8 × E8 heterotic string is related to an eleven-dimensional theory on the orbifold ℝ10 × S1/ℤ2 in the same way that the Type IIA string in ten dimensions is related to ℝ10 × S1. This in particular determines the strong coupling behavior of the ten-dimensional E8 × E8 theory. It also leads to a plausible scenario whereby duality between SO (32) heterotic and Type I superstrings follows from the classical symmetries of the eleven-dimensional world, just as the SL (2, ℤ) duality of the ten-dimensional Type IIB theory follows from eleven-dimensional diffeomorphism invariance.
