February 23, 1945: During the bloody Battle for Iwo Jima, U.S.
Marines from the 3rd Platoon, E Company, 2nd Battalion, 28th
Regiment of the 5th Division took the crest of Mount Suribachi.
the island’s highest peak and most strategic position, and
raised the U.S. flag.

Marine photographer Louis Lowery, who was with them,
recorded the event. Americans fighting for control of
Suribachi’s slopes cheered the raising of the flag.

Several hours later, more Marines headed up to the crest
with a larger flag. Joe Rosenthal, a photographer with the
Associated Press, met them along the way and recorded
the raising of the second flag along with a Marine still
photographer and a motion-picture cameraman.

On February 23, 1954, a group of children from Arsenal
Elementary School in Pittsburgh, Pennsylvania, received
the first injections of the new polio vaccine developed by
Dr. Jonas Salk.

Thanks to the vaccine, by the 21st century polio cases
were reduced by 99 percent worldwide.

Though not as devastating as the plague or influenza,
poliomyelitis was a highly contagious disease that
emerged in terrifying outbreaks and seemed impossible
to stop.

The most famous victim of a 1921 outbreak in America
was future President Franklin Delano Roosevelt, then a
young politician. The disease spread quickly, leaving
his legs permanently paralyzed.
