Yes. Dr. Fred P. Manget (1880-1979) went from Georgia, USA, to Shanghai, China, as a medical missionary in 1909. In 1912, he rented a building in Huzhou to establish a hospital that could hold about 30 beds. At the end of World War I, Dr. Manget returned to Shanghai and discussed with the representative of the Rockefeller Foundation in China about the Foundation's intention to spread the practice of Western medicine in China. After much negotiation, the Chinese Government agreed to provide 9 acres of land, while the Foundation provided US$30,000 to build a hospital in Huzhou. The remaining needed funds were provided by the Southern Methodist Church and the Northern Baptist Church in the USA. Thus, the small hospital with a small rented building and one doctor was transformed into Huzhou General Hospital (湖州醫院), which had 9 acres of land, over 100 nurses and 100 other personnel, in addition to the most modern medical facilities in China. The facilities included a chemistry laboratory, an X-ray facility and a Nursing School. Later, Japanese troops occupied Huzhou General Hospital. Luckily, the family members of Dr. Manget were able to leave China for the USA. However, Dr. Manget was not willing to leave China. When he saw how badly the Japanese troops treated the Chinese people, he even dared to point out the wrongdoing of the Japanese troops. As a consequence, he was arrested by the Japanese troops, who wrongly accused him of espionage. Later, the Japanese troops released him. Under the strict control of the Japanese troops, Huzhou General Hospital reopened and Dr. Manget worked there for three and a half years. Later, Dr. Manget joined the Flying Tigers and the U.S. Army as a doctor.
