FIRST ELECTRIC GUITAR AWARDED PATENT

See the source image


Versatile, inexpensive and relatively easy to play, the acoustic
guitar was a staple of American rural music in the early 20th
century, particularly black rural music such as the blues. But
a significant physical limitation made it a poor fit in ensembles
made up of brass, woodwind and orchestral string instruments:
The acoustic guitar was simply too quiet.

What transformed the guitar and its place in popular music, and eventually transformed  popular music itself, was the development
of a method for transforming the sound of a vibrating guitar string
into an electrical signal that could be amplified and re-converted
into audible sound at a much greater volume.

The electric guitar—the instrument that revolutionized jazz, blues
and country music and made the later rise of rock and roll possible,
was recognized by the United States Patent Office on August 10,
1937 with the award of Patent #2,089.171 to G.D. Beauchamp for an instrument known as the Rickenbacker Frying Pan.

Inventor G.D. Beauchamp, partner with Adolph Rickenbacher in the Electro String Instrument Corporation of Los Angeles, California,
spent more than five years pursuing his patent on the Frying Pan.

BELL RECEIVED PATENT ON THIS DAY IN 1876

See the source image

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

The Scottish-born Bell worked in London with his father, Melville
Bell, who developed Visible Speech, a written system used to
teach speaking to the deaf. In the 1870s, the Bells moved to
Boston, Massachusetts, where the younger Bell found work as
a teacher at the Pemberton Avenue School for the Deaf. He later
married one of his students, Mabel Hubbard.

While in Boston, Bell became very interested in the possibility of transmitting speech over wires. Samuel F.B. Morse’s invention
of the telegraph
in 1843 had made nearly instantaneous
communication possible between two distant points.

With the help of Thomas A. Watson, a Boston machine shop
employee, Bell developed a prototype.

ASPIRIN PATENT FILED ON THIS DAY IN 1899

Felix Hoffmann
(21 January 1868 – 8 February 1946)


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Now the most common drug in household medicine cabinets, acetylsalicylic acid was originally made from a chemical found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.)
