Thomas
Alva Edison
Thomas Alva Edison was born on
February 11, 1847 in Milan, Ohio; the seventh and last child
of Samuel and Nancy Edison. When Edison was seven his family
moved to Port Huron, Michigan. Edison lived here until he
struck out on his own at the age of sixteen. Edison had very
little formal education as a child, attending school only
for a few months. He was taught reading, writing, and arithmetic
by his mother, but was always a very curious child and taught
himself much by reading on his own. This belief in self-improvement
remained throughout his life.
Edison began working at an early age, as most
boys did at the time. At thirteen he took a job as a newsboy,
selling newspapers and candy on the local railroad that ran
through Port Huron to Detroit. He seems to have spent much
of his free time reading scientific, and technical books,
and also had the opportunity at this time to learn how to
operate a telegraph. By the time he was sixteen, Edison was
proficient enough to work as a telegrapher full time.
The development of the telegraph was the first
step in the communication revolution, and the telegraph industry
expanded rapidly in the second half of the 19th century. This
rapid growth gave Edison and others like him a chance to travel,
see the country, and gain experience. Edison worked in a number
of cities throughout the United States before arriving in
Boston in 1868. Here Edison began to change his profession
from telegrapher to inventor. He received his first patent
on an electric vote recorder, a device intended for use by
elected bodies such as Congress to speed the voting process.
This invention was a commercial failure. Edison resolved that
in the future he would only invent things that he was certain
the public would want.
Edison moved to New York City in 1869. He
continued to work on inventions related to the telegraph,
and developed his first successful invention, an improved
stock ticker called the "Universal Stock Printer".
For this and some related inventions Edison was paid $40,000.
This gave Edison the money he needed to set up his first small
laboratory and manufacturing facility in Newark, New Jersey
in 1871. During the next five years, Edison worked in Newark
inventing and manufacturing devices that greatly improved
the speed and efficiency of the telegraph. He also found to
time to get married to Mary Stilwell and start a family.
In 1876 Edison sold all his Newark manufacturing
concerns and moved his family and staff of assistants to the
small village of Menlo Park, twenty-five miles southwest of
New York City. Edison established a new facility containing
all the equipment necessary to work on any invention. This
research and development laboratory was the first of its kind
anywhere; the model for later, modern facilities such as Bell
Laboratories, this is sometimes considered to be Edison's
greatest invention. Here Edison began to change the world.
The first great invention developed by Edison
in Menlo Park was the tin foil phonograph. The first machine
that could record and reproduce sound created a sensation
and brought Edison international fame. Edison toured the country
with the tin foil phonograph, and was invited to the White
House to demonstrate it to President Rutherford B. Hayes in
April 1878.
Edison next undertook his greatest challenge,
the development of a practical incandescent, electric light.
The idea of electric lighting was not new, and a number of
people had worked on, and even developed forms of electric
lighting. But up to that time, nothing had been developed
that was remotely practical for home use. Edison's eventual
achievement was inventing not just an incandescent electric
light, but also an electric lighting system that contained
all the elements necessary to make the incandescent light
practical, safe, and economical. After one and a half years
of work, success was achieved when an incandescent lamp with
a filament of carbonized sewing thread burned for thirteen
and a half hours. The first public demonstration of the Edison's
incandescent lighting system was in December 1879, when the
Menlo Park laboratory complex was electrically lighted. Edison
spent the next several years creating the electric industry.
In September 1882, the first commercial power station, located
on Pearl Street in lower Manhattan, went into operation providing
light and power to customers in a one square mile area; the
electric age had begun.
The success of his electric light brought
Edison to new heights of fame and wealth, as electricity spread
around the world. Edison's various electric companies continued
to grow until in 1889 they were brought together to form Edison
General Electric. Despite the use of Edison in the company
title however, Edison never controlled this company. The tremendous
amount of capital needed to develop the incandescent lighting
industry had necessitated the involvement of investment bankers
such as J.P. Morgan. When Edison General Electric merged with
its leading competitor Thompson-Houston in 1892, Edison was
dropped from the name, and the company became simply General
Electric.
This period of success was marred by the death
of Edison's wife Mary in 1884. Edison's involvement in the
business end of the electric industry had caused Edison to
spend less time in Menlo Park. After Mary's death, Edison
was there even less, living instead in New York City with
his three children. A year later, while vacationing at a friends
house in New England, Edison met Mina Miller and fell in love.
The couple was married in February 1886 and moved to West
Orange, New Jersey where Edison had purchased an estate, Glenmont,
for his bride. Thomas Edison lived here with Mina until his
death.
When Edison moved to West Orange, he was doing
experimental work in makeshift facilities in his electric
lamp factory in nearby Harrison, New Jersey. A few months
after his marriage, however, Edison decided to build a new
laboratory in West Orange itself, less than a mile from his
home. Edison possessed the both the resources and experience
by this time to build, "the best equipped and largest
laboratory extant and the facilities superior to any other
for rapid and cheap development of an invention ". The
new laboratory complex consisting of five buildings opened
in November 1887. A three story main laboratory building contained
a power plant, machine shops, stock rooms, experimental rooms
and a large library. Four smaller one story buildings built
perpendicular to the main building contained a physics lab,
chemistry lab, metallurgy lab, pattern shop, and chemical
storage. The large size of the laboratory not only allowed
Edison to work on any sort of project, but also allowed him
to work on as many as ten or twenty projects at once. Facilities
were added to the laboratory or modified to meet Edison's
changing needs as he continued to work in this complex until
his death in 1931. Over the years, factories to manufacture
Edison inventions were built around the laboratory. The entire
laboratory and factory complex eventually covered more than
twenty acres and employed 10,000 people at its peak during
World War One (1914-1918).
After opening the new laboratory, Edison began
to work on the phonograph again, having set the project aside
to develop the electric light in the late 1870s. By the 1890s,
Edison began to manufacture phonographs for both home, and
business use. Like the electric light, Edison developed everything
needed to have a phonograph work, including records to play,
equipment to record the records, and equipment to manufacture
the records and the machines. In the process of making the
phonograph practical, Edison created the recording industry.
The development and improvement of the phonograph was an ongoing
project, continuing almost until Edison's death.
While working on the phonograph, Edison began
working on a device that, "does for the eye what the
phonograph does for the ear", this was to become motion
pictures. Edison first demonstrated motion pictures in 1891,
and began commercial production of "movies" two
years later in a peculiar looking structure, built on the
laboratory grounds, known as the Black Maria. Like the electric
light and phonograph before it, Edison developed a complete
system, developing everything needed to both film and show
motion pictures. Edison's initial work in motion pictures
was pioneering and original. However, many people became interested
in this third new industry Edison created, and worked to further
improve on Edison's early motion picture work. There were
therefore many contributors to the swift development of motion
pictures beyond the early work of Edison. By the late 1890s,
a thriving new industry was firmly established, and by 1918
the industry had become so competitive that Edison got out
of the movie business all together.
The success of the phonograph and motion pictures
in the 1890s helped offset the greatest failure of Edison's
career. Throughout the decade Edison worked in his laboratory
and in the old iron mines of northwestern New Jersey to develop
methods of mining iron ore to feed the insatiable demand of
the Pennsylvania steel mills. To finance this work, Edison
sold all his stock in General Electric. Despite ten years
of work and millions of dollars spent on research and development,
Edison was never able to make the process commercially practical,
and lost all the money he had invested. This would have meant
financial ruin had not Edison continued to develop the phonograph
and motion pictures at the same time. As it was, Edison entered
the new century still financially secure and ready to take
on another challenge.
Edison's new challenge was to develop a better
storage battery for use in electric vehicles. Edison very
much enjoyed automobiles and owned a number of different types
during his life, powered by gasoline, electricity, and steam.
Edison thought that electric propulsion was clearly the best
method of powering cars, but realized that conventional lead-acid
storage batteries were inadequate for the job. Edison began
to develop an alkaline battery in 1899. It proved to be Edison's
most difficult project, taking ten years to develop a practical
alkaline battery. By the time Edison introduced his new alkaline
battery, the gasoline powered car had so improved that electric
vehicles were becoming increasingly less common, being used
mainly as delivery vehicles in cities. However, the Edison
alkaline battery proved useful for lighting railway cars and
signals, maritime buoys, and miners lamps. Unlike iron ore
mining, the heavy investment Edison made over ten years was
repaid handsomely, and the storage battery eventually became
Edison's most profitable product. Further, Edison's work paved
the way for the modern alkaline battery.
By 1911, Thomas Edison had built a vast industrial
operation in West Orange. Numerous factories had been built
through the years around the original laboratory, and the
staff of the entire complex had grown into the thousands.
To better manage operations, Edison brought all the companies
he had started to make his inventions together into one corporation,
Thomas A. Edison Incorporated, with Edison as president and
chairman. Edison was sixty-four by this time and his role
with his company and in life began to change. Edison left
more of the daily operations of both the laboratory and the
factories to others. The laboratory itself did less original
experimental work and instead worked more on refining existing
Edison products such as the phonograph. Although Edison continued
to file for and receive patents for new inventions, the days
of developing new products that changed lives and created
industries were behind him.
In the 1915, Edison was asked to head the
Naval Consulting Board. With the United States inching closer
towards the involvement in World War One, the Naval Consulting
Board was an attempt to organize the talents of the leading
scientists and inventors in the United States for the benefit
of the American armed forces. Edison favored preparedness,
and accepted the appointment. The Board did not make a notable
contribution to the final allied victory, but did serve as
a precedent for future successful cooperation between scientists,
inventors and the United States military. During the war,
at age seventy, Edison spent several months on Long Island
Sound in a borrowed navy vessel experimenting on techniques
for detecting submarines.
Edison's role in life began to change from
inventor and industrialist to cultural icon, a symbol of American
ingenuity, and a real life Horatio Alger story. In 1928, in
recognition of a lifetime of achievement, the United States
Congress voted Edison a special Medal of Honor. In 1929 the
nation celebrated the golden jubilee of the incandescent light.
The celebration culminated at a banquet honoring Edison given
by Henry Ford at Greenfield Village, Ford's new American history
museum, which included a complete restoration of the Menlo
Park Laboratory. Attendees included President Herbert Hoover
and many of the leading American scientists and inventors.
The last experimental work of Edison's life
was done at the request of Edison's good friends Henry Ford,
and Harvey Firestone in the late 1920s. They asked Edison
to find an alternative source of rubber for use in automobile
tires. The natural rubber used for tires up to that time came
from the rubber tree, which does not grow in the United States.
Crude rubber had to be imported and was becoming increasingly
expensive. With his customary energy and thoroughness, Edison
tested thousands of different plants to find a suitable substitute,
eventually finding a type of Goldenrod weed that could produce
enough rubber to be feasible. Edison was still working on
this at the time of his death.
During
the last two years of his life Edison was in increasingly
poor health. Edison spent more time away from the laboratory,
working instead at Glenmont. Trips to the family vacation
home in Fort Myers, Florida became longer. Edison was past
eighty and suffering from a number of ailments. In August
1931 Edison collapsed at Glenmont. Essentially house bound
from that point, Edison steadily declined until at 3:21 am
on October 18, 1931 the great man died.
