The New York Times has a nice obituary Michael W. Davidson, a Success in Microscopes and Neckwear, Dies at 65
I did not know Davidson personally but I did benefit from his art. I visited the National High Magnetic Field Lab at Florida state several times in the 1990s. In appreciation my host Jim Brooks gave me a few of the neckties [which I still wear, on the rare event I actually wear a tie!] and a series of prints of images of Australian products such as that of Vegemite below. I still have these prints on display in my office.
The website Molecular expressions contains not just a gallery of many beautiful microscope images but also more technical discussions about microscopy.
One thing I did not know about Davidson that I learnt from the obituary was the important role he played in the work for which the Chemistry Nobel Prize of 2014 was awarded.
