Andrew Ranicki

British mathematician and professor (1948–2018)

The Chair of Algebraic Surgery at the University of Edinburgh was held by Andrew Ranicki, a researcher whose career spanned decades of inquiry into algebraic topology. Born in 1948 in London, he navigated a path through international academic institutions before settling in Scotland, where he contributed extensively to the study of manifolds and mathematical surgery until his passing in 2018.

Early Education and Academic Foundation

Born Andrzej Aleksander Ranicki on 30 December 1948, he moved between Warsaw, Frankfurt am Main, and Hamburg during his youth. At sixteen, he attended the King's School, Canterbury. He later enrolled at Trinity College, Cambridge, where he studied under topologists Andrew Casson and John Frank Adams. After earning a Bachelor of Arts degree in 1969, he completed his doctoral studies in 1973, focusing on algebraic L-theory. Between 1972 and 1977, he served as a Fellow of Trinity College.
