The polarizabilities of the proton are fundamental quantities which describe the structure and response of the proton. They are best accessed via Compton scattering. At the MAinzer Microtoron (MAMI), the MAMI electron beam is converted to a quasi-mono-energetic tagged photon beam, with options to produce unpolarized, circularly- or linearly-polarized photons. Over the past few years, this photon beam has been employed with a variety of targets to allow access to scalar and spin polarizabilities of the proton and neutron. The experiments make use of the large-solid-angle coverage of the Crystal Ball and TAPS detector system to suppress the many large-cross-section background reactions while allowing a wide kinematic coverage. We will review the experimental program, and show the latest results on the scalar polarizabilites of the proton.
