Carl R. Woese, who overturned one of the major dogmas of biology with the discovery of Archaea, the third domain of life, passed away following complications from pancreatic cancer at the age of 84 on December 30, 2012.

Carl was a long-time member of the Department of Microbiology and both a founding member and an inspirational figure at the IGB. We invite family, friends, and colleagues to share their memories and condolences here.
