Thompson's most significant work abroad took place in Germany in the early 1930s. While working in Munich, Thompson met and interviewed Adolf Hitler for the first time in 1931. This would be the basis for her subsequent book, "I Saw Hitler", in which she wrote about the dangers of him winning power in Germany. Thompson described Hitler in the following terms: "He is formless, almost faceless, a man whose countenance is a caricature, a man whose framework seems cartilaginous, without bones. He is inconsequent and voluble, ill poised and insecure. He is the very prototype of the little man."
