Curious?

I have Google as my primary homepage and every time I open one, I’d usually see something like this:
A Google page with something like a some sort of a logo, but did you know that this logo is a tribute to a scientist named Dennis Gabor? I think he came up with holography. Here’s what I found about him online:
[b. Budapest, June 5, 1900, d. London, February 9, 1979]
Gabor got his first patent at the age of 11 (for a carousel using real tethered airplanes). He studied electrical engineering in Germany, where he later developed the modern-day mercury-vapor lamp. After moving to England in 1933, he worked on electron microscope improvement, which led him in 1947 to conceive of a hologram, a method of using interference patterns in waves to record all information produced by an object reflecting or refracting the waves. His first holograms using mercury-vapor lamps demonstrated the principle, but were dim and difficult to view. Holograms require a coherent set of waves, not easily available until the advent of the laser in 1960. By 1964 holograms using lasers were producing three-dimensional images and since then many other applications of holograms have been developed.
