Gabriel Andrew Dirac (1925–1984) was a mathematician who mainly worked in graph theory. He stated a sufficient condition for a graph to contain a Hamiltonian circuit. Dirac received his Ph.D. in 1952 from the University of London.[1] Dirac was professor of mathematics in the University of Aarhus in Denmark. He was the stepson of Paul Dirac and nephew of Eugene Wigner.
