Sir Timothy John Berners-Lee

On April 30, 1993, four years after publishing a proposal for
“an idea of linked information systems,” computer scientist
Tim Berners-Lee (above) released the source code for the
world’s first web browser and editor. Originally called Mesh,
the browser that he dubbed WorldWideWeb became the first
royalty-free, easy-to-use means of browsing the emerging
information network that developed into the internet as we
know it today.

Berners-Lee was a fellow at CERN, the research organization headquartered in Switzerland. Other research institutions like
the Massachusetts Institute of Technology and Stanford
University had developed complex systems for internally
sharing information, and Berners-Lee sought a means of
connecting CERN’s system to others.

Hymen L. Lipman (1817-1893)

(FOXNEWS) – Philadelphia inventor Hymen L. Lipman rushed
heroically to the aid of mistake-prone schoolchildren, artists
and draftsmen everywhere when he secured the patent for the
pencil with eraser on this day in history, March 30, 1858. 

"Be it known that I, Hymen L. Lipman, of Philadelphia, in the
county of Philadelphia and State of Pennsylvania, have
invented a new and useful Lead-Pencil and Eraser;" the
visionary wrote in his patent application.

"I make a lead-pencil in the usual manner, reserving about
one-fourth of the length, in which I make a groove of suitable
size … and insert in this groove a piece of prepared India
rubber (or other erasive substance) secured to said pencil
by being glued at one edge."

The eraser, he noted in his application, "is particularly valuable 
for removing or erasing lines, figures, etc., and not subject to
be soiled or mislaid on the table or desk" — as if the purpose
of an eraser was unknown to mid-19th century consumers. 

On March 7, 1876, 29-year-old Alexander Graham Bell received
a patent for his revolutionary new invention: the telephone.

Thomas Alva Edison (February 11, 1847 – October 18, 1931)

Edison developed many devices in fields such as electric
power generation, mass communication, sound recording,
and motion pictures.      

Wham-O Manufacturing Co. of California began producing the
Pluto Platter — soon renamed the Frisbee. 

"The Frisbee started off as nothing more than a container that
carried pies," reported University of Southern California online engineering publication Illumin Magazine, which analyzed the
physics and history of the toy.

"However, through the ingenuity of some college students, the inventiveness of Fred Morrison, and the marketing savvy of the
Wham-O Manufacturing Company, it eventually became an
immensely popular and internationally recognized toy."
