In Memoriam

Nobel Prize winner Thomas Weller died August 23 at his home in Massachusetts, reports the New York Times. He was 93. Weller specialized in tropical medicine and won the Nobel Prize in Physiology or Medicine in 1954 with two colleagues for their work applying tissue culture research to studying viruses that enabled the development of the Salk and Sabin polio vaccines. Weller later studied schistosomiasis, varicella zoster viruses, and the German measles.

Chris Curtis' colleagues remember his work as a medical entomologist. Curtis worked on developing ways to control insect vectors for tropical diseases such as malaria and elephantiasis. He also developed mathematical models of insecticide resistance that are still being used. Curtis was 63 and had cancer.
