Dr. Habachi spent 30 years in the Antiquities Department of the Egyptian Government, ending his career as Chief inspector.

During this period he spent an enormous amount of time in numerous dig sites in Egypt and the Sudan.

He left government work to accept a position at the Oriental Institute of the University of Chicago as an Archaeological Consultant to its Nubian Expedition.

When a detailed study of the topography of the site and its surroundings was made by Manfred Bietak of the Austrian Archaeological Institute in the 1980s, Habachi's hypothesis was confirmed.

Bietak's mission revealed that the actual Hyksos capital was indeed Tell al-Dab'a.Full bibliography in J. Kamil, Labib Habachi.
