Vale Isabel Joy Bear
It is with heavy hearts that we share the passing of Isabel ‘Joy’ Bear (1927 – 2021).
Joy led research in many aspects of mineral chemistry. Her work contributed to the identification and description of ‘petrichor’.
This term is used to describe the unique odour that occurs just before rain. The smell comes about when increased humidity fills the pores of stones (rocks, soil, etc.) with tiny amounts of water.
We are thankful to Joy for her lasting legacy and the impact she has made to science. Her work will continue to live on and affect the lives of so many.
If you would like to send us your own stories and memories of Joy, please email alumni@csiro.au
Joy’s impact and successes were many – read more about her life and achievements.
A famous discovery was identifying the distinctive smell of rain coined as petrichor.
Kathie McGregor was on ABC’s Australia Wide and talked about Joy – you can listen to her here (starts at 18:18).
A personal tribute by Claire Manson
I had the pleasure of knowing Joy Bear for many years when I worked in the CPSE / Minerals Division and I know many of you also knew her. Joy was such as lovely, kind and very smart person. Joy was so generous with her time for many years after she retired. She mentored CSIRO early career researchers and took the time to review their scientific papers. And whenever we had a seminar by a researcher she was always the first in the room to be there to participate. Joy’s enthusiasm and passion for science and to support the next generation of researchers was brilliant and highly valued. Her memory and long lasting impact for CSIRO will be cherished.
A personal tribute by Dr Malisja de Vries
I had the honour and privilege to work with Joy for many years. An inspiration to women in science, to anyone to fight for fairness and of course, a wonderful sense of humour. A 70 year dedication to science, a productive career, and the struggles she endured as a women (minority group) in CSIRO in the day, she still had time to support young scientists.
Here is a list of literature that Joy produced during her career:
