A Brief History of the Second Solar Spectrum


The development of the ZIMPOL principle at ETH Zurich led to a dramatic increase in our observational knowledge of the solar scattering polarization spectrum, now known as the Second Solar Spectrum. This contribution summarizes the historical developments of this field with a special focus on the observational events between 1994 and 1996 when many interesting things happened that cannot be found in the literature.
