Using the CLEO detector at the Cornell [Formula presented] storage ring CESR we study the two-photon production of Λ[Formula presented], making the first observation of γγ→Λ[Formula presented]. We present the cross section for γγ→Λ[Formula presented] as a function of the [Formula presented] center of mass energy and compare it to that predicted by the quark-diquark model.
