C.S. Seshadri, one of the leading mathematicians of independent India, passed away late on July 17 in Chennai, he was 88. A leader in the field of algebraic geometry, he made breakthroughs that lie at the base of many branches of this discipline. Themes that can be traced in whole or substantial part to Seshadri include projective modules over polynomial rings, geometric invariant theory, moduli theory, vector bundles on curves, the Narasimhan-Seshadri theorem, parabolic bundles, standard monomial theory and the geometry of Schubert varieties. Seshadri began his career at the Tata Institute of Fundamental Research as one of the first batch of graduate students. He moved to Chennai in 1984, to the Institute of Mathematical Sciences. In 1989, he got an opportunity to start the School of Mathematics as part of the SPIC Science Foundation, which has evolved into the Chennai Mathematical Institute (CMI).
