Print advertisement for an electron microscope and other electronics manufactured and sold by the Radio Corporation of America (RCA) for various scientific and industrial applications. The advertisement features an illustrated depiction of a bacteriologist viewing samples of the influenza virus under magnification. The accompanying text details the electron microscope's ability to make the infinitesimal visible through the use of electrons instead of light for illumination.

Viruses Through the Looking-Glass

The electron microscope brought about a paradigm shift in virology in the middle of the twentieth century.
