Galaxy clusters preserve important information on the development of large scale structure in the Universe and the formation and evolution of galaxies. It is advantageous to work longward of 1 μm when studying high‐z clusters because of dust obscuration. This is especially true for z>2, where we expect the bulk of star formation to occur in heavily obscured environments. One may also wish to measure emission in the rest‐frame optical and near‐infrared wavelength ranges, which shift to the near and mid‐infrared part of the spectrum for z>1. Two projects are outlined where infrared observations, including those made with the Spitzer Space Telescope, play key roles: an investigation of the mechanism behind the radio Butcher‐Oemler effect in z∼0.5 clusters and a wide field emission line search for clusters of young galaxies at z>2.
