Janez Janež (pronounced [ˈjaːnɛs ˈjaːnɛʃ]; January 14, 1913 – October 11, 1990) was a Slovene medical doctor and surgeon who worked for most of his life in mainland China and Taiwan. In Chinese he is known as Fan Fenglong (simplified Chinese: 范凤龙; traditional Chinese: 范鳳龍) or simply Doctor Fan (simplified Chinese: 范医生; traditional Chinese: 范醫生; pinyin: Fan yisheng).
Janež was born on January 14, 1913 in Dolsko near Ljubljana, Slovenia. His parents Ana and Franc Janež had three other sons (Franc Jr., Karel, and Viktor) and one daughter (Mimi).
After graduating from a classical secondary school, his mother encouraged him to study theology. However, Janež decided to study medicine in Ljubljana, Zagreb, and Graz. He received his doctorate on May 28, 1937. Later he continued specialized studies in Belgrade and Vienna.
He began working as a surgeon at the Ljubljana hospital in 1937. He continued to work as physician and surgeon during World War II. During the war he was neither militarily nor politically active. He did not collaborate with the German or Italian forces, but after the war Yugoslav communist authorities accused him of collaborationism and put him on a death-sentence list. To save his life, he fled to a refugee camp in Carinthia, Austria. This camp was under British military command. When Yugoslavia demanded the repatriation of these refugees, British soldiers loaded them on a train, saying that they were going to Italy. However, Janež suspected that they were going in wrong direction and he fled again. Most of the people on the train were murdered without trial at Kočevje Rog and several other locations in Slovenia.
