Dennis Gabor is born In Budapest, oldest son of Bertalan Gabor, director of a mining company, and his wife Adrienne (née Jacobovits).

Dennis Gabor works as a Reader in Electron Physics at the Imperial College in London.

Dennis Gabor earns his Phd at Technische Hochschule. His doctorate work concerns the development of one of the first high speed cathode ray oscillographs, during the realization of which he makes the first iron-shrouded magnetic electron lens.

Gabor becomes Professor of applied electron physics. With his doctorands he works on several topics: the elucidation of Langmuir's Paradox, the creation of a Wilson cloud chamber, a holographic microscope, a new electron-velocity spectroscope, a flat thin colour television tube, and a new type of thermionic converter. He leads also theoretical works including communication theory, plasma theory, magnetron theory and scheme of fusion.

Dennis Gabor works as a research engineer at the Physics Laboratory of Siemens and Halske Co. There, he designs high-tension lines and begins to pay special attention to electron optics. While there he invents the molybdenum tape seal, a crucial improvement to the mercury lamp.

Dennis Gabor attends Technische Hochschule in Berlin. Here he studies engiinering. He is also interested in Physics, for this reason he sneaks over to University of Berlin to attend lectures helded by Einstein, Planck, Nernst and von Laue.

Dennis Gabor enters Markó Street High School, among the best schools in Budapest at the time. Here, Gabor is the junior president of the Society of Mathematics and Natural Sciences of the school.

Dennis Gabor works for British Thomson-Houston Company on an inventor's agreement studying the improvement of the resolving power of the electron microscope. The electron microscope increases resolving power a hundredfold over the finest light microscopes, but it still doesn’t allow scientists to examine atomic lattices. The image is distorted in fuzziness and sphericity. Improving the former, worsens the latter, and vice-versa. During these fruitful years at British Thomson-Houston Company, he writes his first papers on communication theory.

Dennis Gabor becomes Staff Scientist of CBS Laboratories, in Stamford, where he collaborates with his lifelong friend, CBS Labs' president Dr. Peter C. Goldmark in many new schemes of communication and display.

Dennis Gabor dies at 78 in a nursing home in South Kensington, London.

Dennis Gabor attends the Technical University of Budapest. He leaves during the third year because of his distaste for registering for military service under a reactionary government. His formal educationwill be completed at the Technische Hochschule in Berlin.

After his retirement Dennis Gabor remains connected with Imperial College as a Senior Research Fellow.

Dennis Gabor enters Szemere Street Elementary School. He graduates with outstanding results. Gabor gets his first patent at the age of 11 for a carousel using real tethered airplanes.

Dennis Gabor receives the Nobel prize in Physics "for his invention and development of the holographic method".

Studying a way to overcome the limit to resolution, Gabor conceives the idea of holography at that time called "wavefront reconstruction". Hologram is the method of using interference patterns in waves to record all information produced by an object reflecting or refracting the waves. Gabor first holograms using mercury-vapor lamps demonstrate the principle, but are dim and difficult to view. Holograms require a coherent set of waves, not easily available until the advent of the laser in 1960.

When Hitler comes to power, Dennis Gabor leaves Germany to return to Budapest to work at Tungsram Electron Tube Research Institute. Here he develops the plasma lamp.
