uscmed.sc.edu Each year, the Microscopy Society of America (MSA) pro-
vides several major awards for outstanding contributions to the fields of microscopy and microanalysis and for service to the Society. While recipients of these awards are listed under the tab Awards & Scholarships – Society Awards | Micros- copy Society of America on the MSA homepage, little infor- mation as to why awards were bestowed is provided. In this initial installment of what will become an annual contribu- tion to Microsocopy Today, Miaofang Chi, Chair of the MSA Awards Committee, and I provide a perspective on the impor- tant contributions of the 2020 Award winners. Te informa- tion presented here represents a short summary of information provided in the awardees’ nomination packages. Guidelines, including deadlines for nominating individuals for these and other MSA awards, can be found by following the above link.
Distinguished Scientist Awards Distinguished Scientist Awards annually recognize
a preeminent senior scientist, from each of the biological and physical sciences, who has a long-standing record of achievement during his or her career in the field of microscopy or microanalysis.
Physical Sciences Distinguished Scientist: David Seidman Broadly speaking, micros-
copy advances fall into two categories; those related to advancing microscope tech- nology and those related to the applications of the technology. David Seidman is a rare indi- vidual who has advanced both. David is the embodiment of the physical materials scientist who

state-of-the-
art microscopy for the infor- mation it provides. His most outstanding contributions are primarily in the applications
science. Yet, perhaps by necessity, he has actively pushed the development of microscopy science and technology, and espe- cially atom probe field-ion microscopy (APFIM). Few of the great scientists in our field can fairly claim this combination of achievement.
10 doi:10.1017/S1551929521000699 As one of the early pioneers in the field of APFIM, Seid-
man established several basic capabilities of the technology. He established the first laboratory in the world dedicated to study quantitatively the fundamental properties of point defects in quenched or irradiated metals with FIM. To understand the basic physics of FIM, he initiated a series of experiments on the process of field-ionization, which involves the quan- tum mechanical tunneling of an imaging gas atom outermost electron into an FIM specimen. He used film-based movies of FIM images of tungsten specimens as they field evaporated to discern vacancy distributions in ion irradiation displacement cascades. In 1970, his three-dimensional reconstructions of the displacement cascades illuminated this basic phenomenon for the first time, and the work still stands as the only three-dimen- sional images of vacancies in materials nearly 50 years later. With approximately 500 publications and 20,000 citations of his work, Seidman exemplifies the title of Distinguished Scientist.
Biological Sciences Distinguished Scientist: Xiaowei Zhuang Dr. Zhuang’s inventions
and discoveries in super-reso- lution and genome-scale imag- ing have had widespread impact on scientific research, health, and medicine. In 2006, Zhuang reported her invention of sto- chastic optical
microscopy (STORM), a found- ing member of the single-mol- ecule-based

imaging methods. Te spatial resolution of light microscopy is classically limited by the diffrac- tion of light to a few hundred nanometers, which detailed

many subcellular structures. STORM overcomes the diffrac- tion limit by exploiting Zhuang’s discovery of photoswitchable dyes to separate spatially unresolvable molecules in time. In her original STORM paper, Zhuang demonstrated two-dimensional fluorescence imaging of biomolecular structures with 20 nm resolution, a drastic improvement over the diffraction limit. A major milestone in the super-resolution imaging field, Zhuang’s 2006 paper has been cited approximately 5,500 times.
