As
ASME celebrates its 125th anniversary this year, Mechanical Engineering
will run articles each month highlighting key influences in the Society's
development. This, the second in our series, explores ASME's eventful first
and second decades, during which the mechanical engineer reached new heights
in professional stature amid a flurry of inventions and new discoveries.
In 1888, George Westinghouse
was investigating a motor for his alternating current electrical system.
He had developed ac power two years earlier, and it offered a transmission
advantage over the direct current system of Thomas Edison: The introduction
of a transformer, to step voltages up or down, permitted efficient power
transmission over longer distances. Edison's system still had the upper
hand, however, because of the dc motor. Direct current not only could
light up the dark, it could also do work, like driving streetcars and
factory machinery.
The 42-year-old Westinghouse, who in 1910 and 1911 would serve as president
of ASME, dived headlong into his project, hiring the best and brightest
to conduct one experiment after another in his Pittsburgh laboratory.
His quest led Westinghouse to Nikola Tesla, a Serbian émigré
who demonstrated a novel motor that could be powered by a rotating magnetic
field. Westinghouse and Tesla proceeded to perfect the device and develop
it into a reliable induction motor that could run on alternating current.

An invention was born, one of hundreds during ASME's first two
decades in existence. The Westinghouse poly-phase system and Thomas Edison's
later ac motor were two of the most significant inventions of the late
19th century, creating a dynamo effect in the rapidly industrializing
nation. Lighting became available to wider urban populations, and city
folk could now ride on electric trolleys, rather than horse-drawn streetcars.
On a grander scale, the genius of Westinghouse and Edison laid the foundation
for electric power generation and mass transit rail electrification efforts,
such as New York City's subway system and the Norfolk and Western
railroad.
The spirit of George Westinghouse and Thomas Edison pervaded engineering
practice in the late 19th century. This era was one of great ideas and
great discoveries. If the 1860s and 1870s encompassed the Great Railway
Age in America, the decades following could be called the Age of Ingenuity.
This period in America's industrialization produced a flurry of
inventions in machine tools, factory equipment, rubber and steel products,
and communications devices. The punch card machine, electrical resistance
welding, automated shoe-making machine, Tungsten steel, wind tunnel for
studying aerodynamics, bottle-making machinethese were only a
few of the amazing inventions, discoveries, and developments in the United
States during the 1880s and 1890s. The total number of patents granted
each year during these 20 years was 21,000, compared to 1,000 a year in
the 1850s.
"America had enormous resources combined with enormous freedom, and these
were factors that drove inventiveness and industrialization during the
late 19th century," said John H. Lienhard, the M.D. Anderson Professor
Emeritus of Mechanical Engineering and History at the University of Houston
and author of a book on the history of technology, Engines of Our Ingenuity,
based on his radio show of the same name.

Thomas Edison was one of the greatest inventors of the time. More than
just a skilled craftsman, Edison took invention to a level of sophistication
and formality. Fulfilling a vision, Edison at the age of 29 established
an enterprisean invention factoryin the quasi-seclusion
of Menlo Park, N.J., where concepts and ideas for new devices incubated
and grew into inventions of practical use to industrialists and consumers.
Edison's operation included laboratories, an electrical testing
shop and machine shop, and a library housing the world's leading
scientific journals. The Wizard of Menlo Park, as Edison became known,
staffed the facility with bright engineers and scientists who shared his
commitment to invention and ingenuity.
"Out of Menlo Park came improved telegraph and telephone systems,
dynamos, electric rail systems, and the photoelectric effect,"
Lienhard said. The phonograph also sprang from Menlo Park.
If engineers were not inventing new products, they were busy improving
upon the systems and processes introduced earlier in England, France,
and Germany. Alexander Holley, one of the founders of ASME, and others
in America advanced the Bessemer process of burning out carbon from molten
metal, enabling the United States to expand its steel industry. By 1900,
the nation's annual output of steel was more than 11 million tons,
making the United States the world leader in steel production.
Steel making was a prime catalyst for economic and industrial growth in
the 19th century. Low-cost Bessemer steel replaced iron for railway construction,
and by the end of the century, 200,000 miles of railroads crisscrossed
the American landscape. And when engineers began to exploit the remarkable
tension and compression characteristics of steel, tall buildings rose,
lending vitality and splendor to Chicago, New York, and other metropolises.
By this time, American manufacturing innovators, led by Ernest L. Ransome
of San Francisco, were demonstrating much success with steel-reinforced
concrete, which became a primary building material in U.S. cities.

Off in the countryside, a boom in farm equipment manufacturing was under
way, spurred by the internal combustion engine. The internal combustion
engine was invented in Germany, and U.S. manufacturers adapted it to the
needs of the farm. By the mid-1890s, U.S. companies were introducing farm
tractors featuring twice the horsepower of earlier steam-traction units,
bringing labor and cost savings to farm operations.
American industrialization hurtled forward during ASME's second
decade, and mechanical engineers were in the forefront. Through inventions
and technical ingenuity and know-how, engineers made great contributions
to industrial productivity and helped corporate employers achieve success
and profitability. By the latter part of the 19th century, engineers had
gained enormous prestige and respect in America, and had risen to a lofty
status in the professional ranks of the day. The education and training
of engineers became formalized, as engineering schools, like the Sibley
School at Cornell University, started programs steeped in the sciences.

Recognizing the role of pure scientific research in product innovation,
industrialists at the turn of the century began establishing dedicated
research laboratories and centers, and staffed these facilities with trained
engineers. These labs, many of which were owned and funded by corporations
seeking to privatize research and corner markets, fueled much innovation
and discovery. The research labs of General Electric, Du Pont, and Goodyear
were among the first to rise from the rapid industrialization and commercialization
at the tail end of the 19th century.
Robert Thurston, ASME's first president, embodied the spirit of
engineering in this period. Like Westinghouse and Edison, Thurston was
a great inventor and innovator. He patented a machine for testing lubricants
and an audio device for recording torsion, and, some 20 years before Kitty
Hawk, sketched designs for flying machines.
Thurston also was one of the strongest proponents of the late 19th-century
engineering sciences movement. Formally educated and strongly influenced
by the great mathematicians and theorists in France, Thurston in 1885
took directorship of the Sibley School at Cornell and transformed it into
a world-renowned institution of scholarly learning.
Thurston's experience at Cornell influenced his vision for ASME.
A writer of numerous technical papers on steam engines and other engineering
subjects, Thurston believed strongly in the value of information exchange.
He envisioned a world regulated by expert technical knowledge, and viewed
the fledging ASME as the appropriate forum for acquiring and dispersing
that knowledge. Thurston's original vision served to shape the
young organization and guide its core activities for the next 125 years.
