Ever wondered how and why certain modern day conveniences were invented? I sure have.
Whether it’s early man’s first use of fire or the birth
of the space shuttle, innovations have always been the major catalysts behind
humankind’s success. Some of these breakthroughs brought about immediate
change, while others humbly laid the groundwork for important developments down
the road. From pioneering inventions to bold scientific and medical
advancements, find out more about 11 innovations that changed the course of
human history.
THE PRINTING PRESS
Prior to the rise of the Internet, no innovation did more
for the spread and democratization of knowledge than Johannes Gutenberg’s
printing press. Developed around 1440 in Mainz, Germany, Gutenberg’s machine
improved on already existing presses through the use of a mould that allowed
for the rapid production of lead alloy type pieces. This assembly line method
of copying books enabled a single printing press to create as many as 3,600
pages per day. By 1500 over 1,000 Gutenberg presses were operating in Europe,
and by 1600 they had created over 200 million new books. The printing press not
only made books affordable for the lower classes, but it helped spark the Age
of Enlightenment and facilitated the spread of new and often controversial
ideas. In 1518 followers of the German monk Martin Luther used the printing
press to copy and disseminate his seminal work “The Ninety-Five Theses,” which
jumpstarted the Protestant Reformation and spurred conflicts like the Thirty
Years’ War (1618-48). The printing press proved so influential in prompting
revolutions, religious upheaval and scientific thought that Mark Twain would
later write, “What the world is today, good and bad, it owes to Gutenberg.”
THE COMPASS
Magnetic compasses may have been made somewhat obsolete
by satellites and global positioning systems, but their impact on early
navigation and exploration was inestimable. Originally invented in China, by
the 14th century compasses had widely replaced astronomical means as the
primary navigational instrument for mariners. The compass provided explorers
with a reliable method for traversing the world’s oceans, a breakthrough that
ignited the Age of Discovery and won Europe the wealth and power that later
fueled the Industrial Revolution. Most importantly, the compass allowed for
interaction—both peaceful and otherwise—between previously isolated world
cultures.
PAPER CURRENCY
Throughout much of human history, money took the form of
precious metals, coins and even raw materials like livestock or vegetables. The
inception of paper money ushered in a bold new era—a world in which currency
could purchase goods and services despite having no intrinsic value. Paper
currency was widely used in China in the ninth century, but did not appear in
Europe until the late 1600s. Spurred on by frequent shortages of coins, banks
issued paper notes as a promise against future payments of precious metals. By
the late 19th century many nations had begun issuing government-backed legal
tender that could no longer be converted into gold or silver. The switch to paper
money not only bailed out struggling governments during times of crisis—as it
did for the United States during the Civil War—but it also ushered in a new era
of international monetary regulation that changed the face of global economics.
Perhaps even more importantly, paper currency was the vital first step in a new
monetary system that led to the birth of credit cards and electronic banking.
STEEL
While early human societies made extensive use of stone,
bronze and iron, it was steel that fuelled the Industrial Revolution and built
modern cities. Evidence of steel tools dates back 4,000 years, but the alloy
was not mass-produced until the invention of the Bessemer Process, a technique
for creating steel using molten pig iron, in the 1850s. Steel then exploded
into one of the biggest industries on the planet and was used in the creation
of everything from bridges and railroads to skyscrapers and engines. It proved
particularly influential in North America, where massive iron ore deposits
helped the United States become one of the world’s biggest economies.
THE ELECTRIC LIGHT
While they are easy to take for granted, all it takes is
a short power outage to remind us of the importance of artificial lights.
Pioneered in the early 19th century by Humphry Davy and his carbon arc lamp,
electric lights developed throughout the 1800s thanks to the efforts of
inventors like Warren de la Rue, Joseph Wilson Swan and Thomas Alva Edison. It
was Edison and Swan who patented the first long-lasting light bulbs in 1879 and
1880, liberating society from a near-total reliance on daylight. Electric
lights went on to be used in everything from home lighting and street lamps to
flashlights and car headlights. The complex networks of wires erected to power
early light bulbs also helped lead to the first domestic electrical wiring,
paving the way for countless other in-home appliances.
DOMESTICATION OF THE HORSE
Since their domestication some 5,500 years ago, horses
have been inextricably tied to human development. They enabled people to travel
great distances and gave different cultures the chance to trade and exchange
ideas and technology. Equine strength and agility meant that horses could also
carry cargo, plow farmland and even clear forests. Perhaps most influential of
all, horses changed the nature of war. Nothing was more feared than a
horse-drawn chariot or a mounted warrior, and societies that mastered the use
of cavalry typically prevailed in battle.
TRANSISTORS
A criminally underappreciated innovation, the transistor
is an essential component in nearly every modern electronic gadget. First
developed in 1947 by Bell Laboratories, these tiny semiconductor devices allow
for precise control of the amount and flow of current through circuit boards.
Originally used in radios, transistors have since become an elemental piece of
the circuitry in countless electronic devices including televisions, cell
phones and computers. The amount of transistors in integrated circuits doubles
nearly every two years—a phenomenon known as Moore’s Law—so their remarkable
impact on technology will only continue to grow.
MAGNIFYING LENSES
Magnifying lenses might seem like an unremarkable
invention, but their use has offered mankind a glimpse of everything from
distant stars and galaxies to the minute workings of living cells. Lenses first
came into use in the 13th century as an aid for the weak-sighted, and the first
microscopes and telescopes followed in the late 16th and early 17th centuries.
Figures like Robert Hook and Anton van Leeuwenhoek would go on to use
microscopes in the early observance of cells and other particles, while Galileo
Galilei and Johannes Kepler employed the telescope to chart Earth’s place in
the cosmos. These early uses were the first steps in the development of
astonishing devices like the electron microscope and the Hubble Space
Telescope. Magnifying lenses have since led to new breakthroughs in an
abundance of fields including astronomy, biology, archaeology, optometry and
surgery.
THE TELEGRAPH
The telegraph was the first in a long line of
communications breakthroughs that later included radio, telephones and email.
Pioneered by a variety of inventors in the 18th and 19th centuries, the
telegraph used Samuel Morse’s famous Morse code to convey messages by
intermittently stopping the flow of electricity along communications wires.
Telegraph lines multiplied throughout the 1850s, and by 1902 transoceanic
cables encircled the globe. The original telegraph and its wireless successors
went on to be the first major advancements in worldwide communication. The
ability to send messages rapidly across great distances made an indelible
impact on government, trade, banking, industry, warfare and news media, and
formed the bedrock of the information age.
ANTIBIOTICS
A giant step forward in the field of medicine,
antibiotics saved millions of lives by killing and preventing the growth of
harmful bacteria. Scientists like Louis Pasteur and Joseph Lister were the
first to recognize and attempt to combat bacteria, but it was Alexander Fleming
who made the first leap in antibiotics when he accidentally discovered the
bacteria-inhibiting mold known as penicillin in 1928. Antibiotics proved to be
a major improvement on antiseptics—which killed human cells along with
bacteria—and their use spread rapidly throughout the 20th century. Nowhere was
their effect more apparent than on the battlefield: While nearly 20 percent of
soldiers who contracted bacterial pneumonia died in World War I, with
antibiotics that number dropped to only 1 percent during World War II.
Antibiotics like penicillin, vancomycin, cephalosporin and streptomycin have
gone on to fight nearly every known form of infection, including influenza,
malaria, meningitis, tuberculosis and most sexually transmitted diseases.
THE STEAM ENGINE
Cars, airplanes, factories, trains, spacecraft—none of
these transportation methods would have been possible if not for the early
breakthrough of the steam engine. The first practical use of external
combustion dates back to 1698, when Thomas Savery developed a steam-powered
water pump. Steam engines were then perfected in the late 1700s by James Watt,
and went on to fuel one of the most momentous technological leaps in human
history during the Industrial Revolution. Throughout the 1800s external
combustion allowed for exponential improvement in transportation, agriculture
and manufacturing, and also powered the rise of world superpowers like Great
Britain and the United States. Most important of all, the steam engine’s basic
principle of energy-into-motion set the stage for later innovations like
internal combustion engines and jet turbines, which prompted the rise of cars and
aircraft during the 20th century.
Clancy's comment: Wow. I'm certainly glad about a few of these. How would we survive today without them? Then again, might be a nice change to live like a caveman.
