In the early 1940s, Labib Habachi led him to believe that Tell el Dab‘a-Qantir were home to Avaris and Pi-Ramesses respectively. Most of his discoveries were only recently published 20 years after his death and nearly 40 years after his excavations. cf. Labib Habachi, Tell el-Dab‘a I: Tell el-Dab‘a and Qantir the Site and Its Connection with Avaris and Piramesse (Vienna: Verlag der Österreichischen Akademie der Wissenschaften, 2001).
