1 ene 1937 año - James Hillier and Albert Prebus assemble a revolutionary microscope

Descripción:

He and Prebus were students when, in 1937, they assembled a model of a microscope that could magnify up to 7,000 times the size of an object – much greater than the 2,000 times magnification produced by optical microscopes used at that time. (Could't find picture of Albert Prebus.)
