Gustav Lindenthal
Gustav Lindenthal (May 21, 1850 – July 31, 1935) was a civil engineer who designed the Queensboro and Hell Gate bridges in New York City, among other bridges. Lindenthal's work was greatly affected by his pursuit for perfection and his love of art. Having received little formal education and no degree in civil engineering, Lindenthal based his work on his prior experience and techniques used by other engineers of the time. Early life Lindenthal was born in Brünn, Austrian Empire, now Brno, Czech Republic in 1850. Lindenthal began to receive practical training in 1866 when he was employed as a mason and carpenter. At the age of 18, Lindenthal left his family to set out to make a life of his own in Vienna, Austria. Career When he arrived in Vienna he became an assistant in the engineering department for the Empress Elisabeth Railway of Austria. Two years later he joined the Union Construction Company, where he gained experience in building incline planes and railroads. ...

Hydraulics
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Pennsylvania Railroad
The Pennsylvania Railroad (reporting mark PRR), legal name The Pennsylvania Railroad Company also known as the "Pennsy", was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. It was named for the commonwealth in which it was established. By 1882, Pennsylvania Railroad had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world.

Hudson River
The Hudson River is a river that flows from north to south primarily through eastern New York. It originates in the Adirondack Mountains of Upstate New York and flows southward through the Hudson Valley to the New York Harbor between New York City and Jersey City, eventually draining into the Atlantic Ocean at Lower New York Bay. The river serves as a political boundary between the states of New Jersey and New York at its southern end. Farther north, it marks local boundaries between several New York counties. The lower half of the river is a tidal estuary, deeper than the body of water into which it flows, occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Even as far north as the city of Troy, the flow of the river changes direction with the tides. The Hudson River runs through the Munsee, Lenape, Mohican, Mohawk, and Haudenosaunee homelands.

Allegheny River
The Allegheny River ( ) is a long headwater stream of the Ohio River in western Pennsylvania and New York (state), New York. The Allegheny River runs from its headwaters just below the middle of Pennsylvania's northern border northwesterly into New York then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio on the "Point" of Point State Park in Downtown Pittsburgh, Pennsylvania.

Atlantic And Great Western Railroad
The Atlantic and Great Western Railroad began as three separate railroads: the Erie and New York City Railroad based in Jamestown, New York; the Meadville Railroad based in Meadville, Pennsylvania (renamed A&GW in April 1858); and the Franklin and Warren Railroad based in Franklin Mills, Ohio (renamed A&GW in January 1853). The owners of the three railroads had been working closely together since an October 8, 1852, meeting in Cleveland to plan an expansion of the "Great Broad Route", the Erie Railroad, through their respective areas. On March 12, 1862, general control of all three companies was placed under a central board made of two directors from each of the companies. The Ohio Board was represented by Marvin Kent and Worthy S. Streator; the Pennsylvania Board by William Reynolds and John Dick; and the New York Board by A. F. Allen and Thomas W. Kennard. William Reynolds was elected President of the Board. The line reached Cleveland on November 18, 1863, and was connecte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
