We have recently obtained ~ 0.5('') resolution images in the Near-Infrared J-, H-, and K-Band of the Sy 1 Galaxy NGC 7469. \ These data, taken on the NTT of ESO on La Silla with MPE's NIR speckle camera, {\sf SHARP}, reveal a complex ring of radius 1.3('') (420 pc at 66 Mpc) at a flux level ~ 2% that of the central source. The morphology of the ring, including several bright knots within the ring, are in good agreement with recent optical continuum, [OIII], and Hα speckle imaging at similar resolution (Mauder et al. 1993, A& A, in press), and with the 6 cm VLA measurements (Wilson et al. 1991, Ap.J., 381, 79). We present a complete analysis of the ring in terms of a starburst phenomenon (Heckman et al. 1986, Ap.J., 305, 157; Wilson et al 1991), as well as a comparison between this system and the Sy 2 NGC 1068.
