It is with great sadness that I’ve learnt of the death of Tim Hawarden. He can be fairly described as one of the godfathers of Herschel thanks to his development of the concept of radiative cooling for space-based infrared telescopes.
As well as being a brilliant astronomer at whichever wavelength he was working in, he was also a truly nice human being. For example, on trips down from Mauna Kea, he’d stop the car and make sure visiting astronomers got to see some of the amazing flora and fauna of the Big Island. I can well remember being astounded when he first showed me the flowers of wild ginger on one such trip.
He’ll be missed.
