Klaus Heinemann
After completion of his Ph.D. thesis in applied physics at the University of Tubingen, Germany,
Klaus worked as an R&D engineer at Siemens AG, Berlin, in the development of the Elmiskop 101
transmission electron microscope.
In 1969, he joined NASA-Ames Research Center as a National Research Council postdoc and worked on high
resolution TEM applications. For his development of dark-field microscopy with annular objective apertures he
received the 1972 NASA Exceptional Scientific Achievement Award.
His research emphasis then shifted to high-resolution in-situ TEM investigations, including in-situ oxidation
and gas reaction studies under controlled (ultra-high) vacuum conditions.
Major scientific milestones (published in over 60 peer-reviewed articles in scientific journals) include revealing
of the (atomic-scale) thickness-dimensions of nanometer-size crystalline particles, building of a 10(-8) Pa high-resolution
TEM specimen handling and reaction chamber,
and the detection and size classification of metal clusters consisting of just a few atoms on amorphous substrates.
