Thomas A. Scott
He was the fourth president of the Pennsylvania Railroad (1874-1880), later the largest publicly traded corporation in the world. He became the U.S. Assistant Secretary of War in 1861, during the American Civil War. To further his railroad investments, he had a leading role in creating what became the Compromise of 1877, which marked the end to the federal interventions and civil rights efforts of the Reconstruction Era in the South.
Scott joined the Pennsylvania Railroad in 1850 as a station agent, and by 1858 was general superintendent. Scott took a special interest in mentoring aspiring railroad employees.
It was during this time, and under the supervision of Scott, that young Andrew Carnegie began working for the Pennsylvania Railroad. Scott taught him the basics of railroading, investment, and management, that had an impact on his later business successes. Their association continued through the Civil War and awhile after, until Carnegie turned his full attention to the iron and steel industry.
The 1846 charter issued by the state of Pennsylvania to the Pennsylvania Railroad was an effort to diffuse power within the company, by giving executive authority to a committee responsible to stockholders, and not individuals. By the 1870s however, power had been centralized in the hands of the officers directed by J. Edgar Thomson and Scott.
Historians have explained the successful partnership of Thomas Scott and J. Edgar Thomson by the melding of their opposite personality traits: Thomson was the engineer, cool, deliberate, and introverted; Scott was the financier, daring, versatile, and a publicity-seeker. In addition, there were their common experiences and values, agreement on the importance of financial success, the financial stability of the Pennsylvania Railroad throughout their partnership, and J. Edgar Thomson's paternalism. J. Edgar Thomson was the President of the Pennsylvania Railroad from 1852 until his death in 1874.
In 1860, Scott became the first Vice President of the Pennsylvania Railroad. From 1871 to 1872, he was briefly the president of the Union Pacific Railroad, then the first transcontinental railroad owner. He was the president of the Pennsylvania Railroad from 1874, upon the death of his partner Thomson, until 1880. The Pennsylvania Railroad expanded from a company of railway lines within Pennsylvania through the 1840s and 1850s, to a transportation empire from the 1860s onwards.
Scott was notoriously secretive about his business dealings, conducting most of his business in private letters, and instructing his business partners to destroy them after they were read.
After the Civil War, Scott was heavily involved in investments in the fast-growing trans-Mississippi River route into Texas, with long-term plans for a southern transcontinental railway line connecting the Southern states and California. However, the 1872 Crédit Mobilier scandal made Congress unwilling to grant railroad companies land grants in the west. The financial Panic of 1873 and subsequent economic depression added obstacles to Scott’s southern transcontinental railroad plans, which he never overcame.
At the outbreak of the American Civil War, Pennsylvania Governor Andrew Curtin called on Scott for his extensive knowledge of the rail and transportation systems of the state.  Scott received a staff commission as a colonel, and in August 1861, President Abraham Lincoln appointed Scott as Assistant Secretary of War. The next year, he helped organize the Loyal War Governors' Conference in Altoona, Pennsylvania. 
Later on, Scott took on the task of equipping a substantial military force for the Union war effort.  He assumed supervision of government railroads and other transportation lines, and made the movement of supplies and troops more efficient and effective for the war effort on behalf of the Union. In one instance, he engineered the movement of 25,000 troops in 24 hours from Nashville to Chattanooga, turning the tide of battle once more to a Union victory. 
Scott also recommended President Lincoln travel covertly by rail to avoid Confederate spies and assassins.
During the American Reconstruction in the aftermath of the Civil War, the Southern states needed their economy and infrastructure restored, and the Northern based railroads competed to acquire routes and construct rail lines in the South. Federal assistance was sought by both special interest groups, but the Crédit Mobilier of America scandal made this difficult in 1872. Congress became unwilling to grant railroad companies land grants in the Southwestern United States.
Scott made a proposal that came to be called the "Scott Plan" by which largely Democratic Southern politicians would give their votes in Congress and state legislatures for federal government subsidies to various infrastructure improvements, including in particular the Texas and Pacific Railway, a scheme headed by Scott. Scott employed the expertise of Grenville Dodge in buying the support of newspaper editors as well as various politicians in order to build public support for the subsidies.
Compromise of 1877
The Scott Plan became a basis for the Compromise of 1877, an informal and unwritten deal which removed federal troops out of state politics in several Southern states and ended the Reconstruction Era.  The compromise's back-stepping on the new post-war civil rights had terrible impacts for African Americans living in the South and other regions. African American historians sometimes call it "The Great Betrayal." 
Great Railroad Strike of 1877
Despite Scott’s best efforts to make the company more efficient, Pennsylvania Railroad continued to lose money through the 1870s. Cost reduction and pay cuts initiated by him resulted in the Pittsburgh railroad riots, location of the worst violence in the Great Railroad Strike of 1877. Scott, often considered one of the first robber barons, suggested that the strikers should be given "a rifle diet for a few days and see how they like that kind of bread." 
Scott suffered a stroke in 1878, which hindered his ability to work. He had already lost his crucial partner, J. Edgar Thomson, in 1874.
