On 6 July 2019 Calvin Quate died aged 95 at his home in Menlo Park, California.</span></em></div><div style="text-align:justify;"><br /><span style="font-family:georgia, 'times new roman', serif;">L<em>ong before the development of AFM, Quate’s research had <a href="https://physics4thecool.blogspot.com/2019/07/how-we-see-small.html" target="_blank">made waves in microscopy</a>. 1978 had seen the announcement of the scanning acoustic microscope, which achieved the sensitivity of optical microscopy but probed samples so softly that it could image the interiors of living cells without damaging them. The technique uses high frequency sound waves in place of light, which penetrate deep into structures to image internal structures non-destructively. It is widely used in quality control of electronic component assembly among other applications such as printed circuit boards and medical products.</em></span></div><div style="text-align:justify;"> </div><p><span style="font-family:georgia, 'times new roman', serif;"><a href="https://physicsworld.com/a/advanced-microscopy-pioneer-leaves-broad-ranging-legacy/" target="_blank">Advanced microscopy pioneer leaves broad ranging legacy</a></span><br /><span style="font-family:georgia, 'times new roman', serif;">Anna Demming, Physics World</span></p></div>
