On November 15, 1867, the first stock ticker was unveiled in New 
York City. The advent of the ticker ultimately revolutionized the
stock market by making up-to-the-minute prices available to
investors around the country.

Prior to this development, information from the New York Stock Exchange, which has been around since 1792, traveled by mail
or messenger.

The ticker was the brainchild of Edward Calahan (1838-1912) who configured a telegraph machine to print stock quotes on streams
of paper tape (the same paper tape later used in ticker-tape
parades).

The patent office awards U.S. Patent No. 743,801 to a
Birmingham, Alabama woman named Mary Anderson
for her “window cleaning device for electric cars and
other vehicles to remove snow, ice or sleet from the
window.”

Though mechanical windshield wipers were standard
equipment in passenger cars by around 1913, Anderson
never profited from the invention.

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

Thomas Alva Edison, one of the most prolific inventors in
history, died of complications of diabetes in his home, 
in Llewellyn Park in West Orange, New Jersey.Edison was
buried behind the home. He was 84

Edison’s last breath is reportedly contained in a test tube
at The Henry Ford museum near Detroit. Ford reportedly
convinced Charles Edison to seal a test tube of air in the
inventor’s room shortly after his death, as a memento.

On October 2, 1965, a team of scientists invented Gatorade,
sports drink to quench thirst, in a University of Florida lab.

The name "Gatorade" is derived from the nickname of the
university’s sports teams. Eventually, the drink becomes
a phenomenon and made its inventors wealthy.

Early in the summer of 1965, University of Florida assistant
football coach Dewayne Douglas met a group of scientists
on campus to determine why many of Florida’s players were
so negatively affected by heat. To replace bodily fluids lost
during physical exertion, Dr. James Robert Cade and his
team of researchers, doctors H. James Free, Dana Shires
and Alex de Quesada, created the now-ubiquitous sports
drink.
