His solution was to create a Japanese language school to train linguists in advance. Reischauer’s warning did not go unheeded. It landed on the desk of Lieutenant (later Commander) Albert Hindmarsh of the U.S. Navy, and he agreed that there were indeed few competent Japanese-speaking officers available. The result was the creation of the U.S. Navy Japanese Language School, which spent most of the war at Boulder, Colorado. In the summer of 1942, at the request of the U.S. Army Signal Corps, Reischauer started running a top-secret course at Arlington Hall in Virginia. Arlington Hall had been a women’s college, but it was taken over by the US Army Signal Intelligence Service in June 1942 and functioned like Bletchley Park in England as a secret cryptanalysis centre. Teaching career Reischauer had a 40-year teaching career at Harvard. He and John King Fairbank developed a popular undergraduate survey of East Asian history and culture. The course, which was known as "Rice Paddies", was the basis for their widely influential textbooks, East Asia: The Great Tradition (1958) and East Asia: The Modern Transformation (1965). Reischauer wrote both for fellow scholars and for the general public, including Japan: Story of a Nation, which was published in several editions. He served as director of the Harvard–Yenching Institute and chairman of the Department of Far Eastern Languages. For his farewell lecture at the Yenching Institute in 1981, students had to compete for seats with faculty colleagues, university officials, and a television crew from Japan. In that crowded scene, he said, "As I remember, there were only two graduate students interested in East Asian studies when I first came here: myself and my brother." Ambassador to Japan Reischauer was appointed US Ambassador to Japan by President John F. Kennedy in the spring of 1961, at a time when US-Japan relations were at a low point following the massive 1960 protests in Japan against the US-Japan Security Treaty. In the immediate aftermath of the protests, Reischauer had traveled to Japan and spoken with various Japanese friends and associates to get a Japanese point of view on the protests. After returning to the United States, Reischauer attracted the attention of Kennedy's transition team when he wrote an article about the protests in the prominent policy journal Foreign Affairs called "The Broken Dialogue with Japan." In this article Reischauer rejected the notion, put forth by the Eisenhower administration, that
