Although the Germans have never played any significant role in Cretan field archaeology, they have made major contributions to the study of Minoan art and architecture. The Americans got off to a great start in the first two decades of the 20th century, with Harriet Boyd and Richard Seager, who dug at Mochols, Pseira and Vasiliki. But they lost interest in Crete after 1920 and were not to return to the island for more than 50 years.
