Portable radios were invented by John F. Mitchell in 1941 when  he 
created the first 2-way radio that was small enough for soldiers to
carry with them during World War II. These radios were called the
“Walkie-talkie.” 

Portable radios became available for home use in 1958 when
Raytheon produced a pocket transistorized radio that cost
$49.95.

The German company Bayer patents aspirin on March 6, 1899.
Now the most common drug in household medicine cabinets, acetylsalicylic acid was originally made from a chemical found
in the bark of willow trees. In its primitive form, the active
ingredient, salicin, was used for centuries in folk medicine,
beginning in ancient Greece when Hippocrates used it to relieve
pain and fever. Known to doctors since the mid-19th century, it
was used sparingly due to its unpleasant taste and tendency to
damage the stomach.

In 1897, Bayer employee Felix Hoffmann found a way to create a
stable form of the drug that was easier and more pleasant to take.
(Some evidence shows that Hoffmann’s work was really done by
a Jewish chemist, Arthur Eichengrun, whose contributions were
covered up during the Nazi era.)

From the March 1911 issue of Pictorial Review.

Ahnelt’s American Fashion Company..
