We are sad to report that one of the "originals" in radio astronomy - Bruce McAdam - died quietly at home on Monday night some 30 years after his retirement from the University of Sydney.
Bruce's first paper dates back 67 years! - https://url.au.m.mimecastprotect.com/s/Ax6uCvl1rKi20vGw6cQf4TQN9dK?domain=ui.adsabs.harvard.edu<https://url.au.m.mimecastprotect.com/s/Ax6uCvl1rKi20vGw6cQf4TQN9dK?domain=ui.adsabs.harvard.edu>
He was full of excellent stories about the Cambridge vs. USyd controversy on radio source counts, having been in the research groups at both schools. And he was in Cambridge in the mid 60s at the peak of the controversies - Steady State vs Big Bang, etc.
Bruce was a great participant at the School of Physics and maintained his interest in Physics to the last. Longstanding members of SIfA and the ASA will remember Bruce and Janice at many functions and ASA meetings over the years, even long after he retired. It was his long service to the Australian astronomical community and the ASA as a Foundation member that prompted the ASA to waive fees for all members with 50+ years of membership. A line in his email reply acknowledging that says so much about him - "Stay active and support young members!”
Details of the funeral should be in Saturday's Sydney Morning Herald.
John
