Holography dates from 1947, when British/Hungarian scientist Dennis Gabor developed the theory of holography while working to improve the resolution of an electron microscope. Gabor, who characterized his work as "an experiment in serendipity" that was "begun too soon," coined the term hologram from the Greek words holos, meaning "whole," and gramma, meaning "message." (see Gabor's autobiography)

Two men held a circle of plastic over a heater in a San Luis Obispo garage in 1948, trying to mold a lip onto the disc's down-turned edge. One of those men would be hailed as the inventor of the Frisbee. The other would die unknown, just as he began to fight for a share of the credit and millions in royalties the Frisbee generated.
George Westinghouse, Jr., the son of a man who made farm machinery in New York, may have been the most productive inventor on record. He helped perpetuate the Industrial Revolution with his instinctive drive to resolve social and commercial obstacles. George's creations changed the way society lived and how people traveled, perhaps more than any single individual.
In geological terms, Long Island was born yesterday.
The oversize sandbar where we live is only the latest, temporary incarnation of a corner of the world that has been continuously reshaped by colliding continents, crumbling mountains, shifting sea level, pounding waves and titanic glaciers. And though Long Island is brand new by the time scale of history, the way we live upon it is profoundly influenced by the remarkable series of transformations that occurred here over hundreds of millions of years.
Granville T. Woods is sometimes called the "Black Thomas Edison" because he invented so many electrical devices. During his lifetime, Granville Woods obtained more than fifty patents for electrical devices that he invented. Granville was called an "extremely prolific and brilliant inventor." He was born in Columbus, Ohio, where he attended school until the age of ten. When he was sixteen years old, Granville got a job as a fireman-engineer with the railroad. He also began to study electrical and mechanical engineering.
A new sitethat is dedicated to the memory of the many African-American inventors that have helped to develop this land of Diaspora that we have built.
This list is by no means the complete list of African-American inventors who have contributed to the successfully creation of this society. This hopefully will be become a community site that shall grow with the help of the electronic users.
Please submit all known inventors who were of African descent and is not currently not listed on this WebPage, to the Web D,signer.This request is made of all known inventors by any persons who want to help maintain the truth. This also is requested of all similar sites.

Everything's relative. Speed, mass, space and time are all subjective. Nor are age, motion or the wanderings of the planets measures that humans can agree on anymore; they can be judged only by the whim of the observer. Light has weight. Space has curves. And coiled within a pound of matter, any matter, is the explosive power of 14 million tons of TNT. We know all this, we are set adrift in this way at the end of the 20th century, because of Albert Einstein.
The popular magazine TIME put together this attractive site of the biographies and accomplishments of the most important scientists and inventors of the 20th Century to accompany TIME's Man of the Century site - that man being Albert Einstein. Essays on the Wright Brothers (aviation), Watson and Crick (genetics), Tim Berners-Lee (the World Wide Web) and many others in between are designed for a mainstream audience, though should prove useful as background information for scholars. The articles were written by established scholars (Peter Gay wrote about Sigmund Freud for instance while Donald Johanson wrote about the Leakey family). The site also includes photographs, audio-clips, and slide presentations.
