This paper is entitled Holography Reinvented, because its theme is simply that each of the three best-known names in holography made their discoveries and inventions without knowing about the work of any the others; that is, each of them invented or reinvented holography, as it were. This is largely a presentation of anecdotal remarks drawn from conversations, observations drawn from historical documents, including some from the Museum of Holography files now at the MIT Museum, and observations drawn from the author's own experiences as holography has evolved. As such, any errors of fact or interpretation are entirely the author's own, as is the slant toward imaging or display holography that will be conspicuous. The three main players are Professors Denis Gabor, Emmett Leith, and Juri Denisyuk. A few other names will come into the story as well, notably: Pieter van Heerden (my former colleague at the Polaroid Research Labs) and Hussein M.A. El-Sum, among others.
