Albert Crewe

Albert Victor Crewe (February 18, 1927 – November 18, 2009) was a British born American physicist and inventor of the modern scanning transmission electron microscope capable of taking still and motion pictures of atoms, a technology that provided new insights into atomic interaction and enabled significant advances in and had wide-reaching implications for the biomedical, semiconductor, and computing industries.
