We just found out today that one of the leaders of the Planck project, Andrew Lange, died yesterday.

He was one of the most respected people not only on the Planck project, but also in the CMB field, cosmology and physics in general. He led the development of some of the most important technical advances in the field, and used these advances to make some the most important cosmological measurements ever. His teams have made measurements of such mind-boggling things as the geometry of the Universe and the energy content of the Universe. He led the design and creation of the heart of the Planck/HFI instrument. His suicide is a staggering shock and a tragic loss for all of us who knew him.
