Jørgen C. Siim was a Danish parasitologist born on October 1, 1915, in Copenhagen. He was involved in toxoplasmosis research from the 1940s, discovering in 1956 that lymphadenopathy is the most common symptom in humans. In 1960, Siim developed a precipitation test for detecting antibodies against toxoplasmosis. He served as the head of the Toxoplasmosis Department at the State Serum Institute in Copenhagen. Collaborating with William M. Hutchison, he received the Robert Koch Prize in 1970 for their work in toxoplasmosis research, and continued his collaboration into the 1980s.
