Lilian Thomson was born in London, England, and studied at the Sorbonne in Paris and the University of Liverpool. In 1911, she met Edgar Ansel Mowrer, a foreign correspondent for The Chicago Daily News. They married in 1916 and spent the 1920s in Italy. During the 1930s, they lived in Germany, witnessing the rise to power of the Nazi regime. Mr. Mowrer won a Pulitzer Prize for his reporting from Germany in 1933, and the couple were forced to leave the country for fear of their lives. Lilian T. Mowrer's first book, Journalist's Wife (1937), was banned in Germany. She and her husband went to live and work in France during the critical years leading up to World War II. They had to flee the German invasion in 1940 and returned to the USA. She went on to write a series of books including Arrest and Exile (1941), Riptide of Aggression (1942), and The United States and World Relations (1952). During the 1940s and 1950s, she was a theatre critic for Vanity Fair and Town and Country magazines, and wrote articles on politics for British newspapers. Her last book was The Indomitable John Scott: Citizen of Long Island (1961), a biography of a 17th-century colonial adventurer.
