Laurence Alexander Wolsey is a Belgian-English mathematician working in the field of integer programming.

His mother Anna Wolsey-Mautner was the daughter of the Viennese Industrialist Konrad David Mautner.

He was invited by George L. Nemhauser as a Post-Doctoral student to CORE in Belgium in 1971.

Wolsey has made seminal contributions in duality theory for integer programming, submodular optimization, the group-theoretic approach and polyhedral analysis of fixed-charge network flow and production planning models.
