On categories and groupoids:
For his long standing collaboration with Ronnie Brown on nonabelian algebraic topology, see here.
His earlier paper
has been influential: it deals with partial operations, following on from his paper
His paper
developed methods that were later on used by Haefliger in assigning a groupoid to a complex of groups.
