**John Michael Boardman** (1938-2021) was a British-born mathematician, specialised in algebraic topology and differential topology. He received his Ph.D. from the University of Cambridge in 1964. His thesis advisor was C. T. C. Wall. He was formerly at the University of Cambridge, England; later a full professor at Johns Hopkins University in Baltimore, USA.

Boardman introduced the stable homotopy category in 1969. His notes on this subject were never formally published, but Rainer Vogt gave a course on this subject in Aarhus in 1969:

He coauthored with Vogt the famous book

**Homotopy invariant algebraic structures on topological spaces**, Springer Lecture Notes in Math 347 (1973).

This book introduced the notion of weak Kan complex that was later popularized by André Joyal under the name quasi-category as a natural basis for the higher category theory of (∞,1)-categories.

On stable cohomology operations, but mostly reviewing the background of stable homotopy theory, Whitehead-generalized cohomology theory, ring spectra, multiplicative cohomology theory, complex oriented cohomology and the examples of KU, MU, BP:

On unstable cohomology operations (hence: in non-abelian cohomology):
