Helga Guderley made St. Margaret’s Bay her home since retiring in 2010 from being a professor of comparative physiology at Université Laval for 30 years.

Helga was born in Dayton Ohio, to recently arrived German immigrants. She did her PhD in Zoology at the University of British Columbia where she met her husband, John Himmelman.
