Carlos Benjamin de Lyra, Brazilian mathematician (Recife 23 November 1927 – São Paulo 21 July 1974)
Proved the existence of a minimal subcomplex of the cubical singular complex of a topological space (1954)
Proved some theorems characterizing spaces having the homotopy type of locally finite or finite polyhedral (1960)
