As revealed by the Herschel Space Observatory, the infrared-submm SEDS of distant radio-loud AGN indicate copious amounts of warm and cold dust. Modeling of these SEDs implies huge star-formation rates, and in addition provides consistency with the unification model for these objects (quasars and radio galaxies). Detailed analysis of the full uv/optical-submm SEDs with a new spectro-chemical evolutionary code provides further quantification of the starburst nature of these “classical” AGN. ALMA images of the cool dust have been obtained, allowing a study of the AGN-starburst connection. Finally, starburst-driven super-winds occur in these objects, providing evidence for negative feedback by the starburst. With a 10 minute introduction towards Sinterklaas inpakpapiermaanaanschijnfase.
