M.S. Narasimhan (1932–2021)
It is with great sadness that I learned of the death of Narasimhan. He had a tremendous impact on algebraic geometry, and moduli spaces of vector bundles on curves in particular, with a career spanning over 60 years. Just a few days a preprint he coauthored appeared on the arXiv, and even the prime minister of India tweeted about him.
His lecture during the VBAC conference in Warwick in 2015 on derived categories of moduli of vector bundles on curves was an important inspiration for many of my current interests.
