Agreement signed by John A. Dix and Sam Sloan - 1872 dated Autograph

General John A. Dix (1798-1879) Dix was born in Boscawen, NH and joined the Artillery as a military cadet at the age of 14. He served in the US Army and attained the rank of captain.

In 1826, Dix married Catherine Morgan, the adopted daughter of Congressman John J. Morgan, who gave Dix a job overseeing his upstate New York land holdings in Cooperstown. Dix and his wife moved to Cooperstown in 1828, and he practiced law in addition to overseeing the land holdings. He was appointed Adjutant General of New York State by Governor Throop. He moved to Albany, New York in 1830, and served as Secretary of State of New York from 1833 to 1839.

Dix was elected as a Democrat to the United States Senate to fill the vacancy caused by the resignation of Silas Wright, Jr., and served from 1845 to 1849. He was not a candidate for reelection, having become a candidate for Governor. He was an unsuccessful Free-Soil candidate for Governor in 1848 losing to Hamilton Fish.

In 1853 Dix was president of the Mississippi and Missouri Railroad. He was appointed postmaster of the City of New York and served from 1860 to 1861. In addition to his military and public duties, he was the president of the Union Pacific from 1863 to 1868 during construction of the First Transcontinental Railroad. Dix was the figurehead for rail baron Thomas C. Durant, in both of his railroad presidencies.

He was appointed United States Secretary of the Treasury by President James Buchanan in 1861. At the outbreak of the Civil War, he sent a telegram to the Treasury agents in New Orleans ordering that: "If any one attempts to haul down the American flag, shoot him on the spot." Although the telegram was intercepted by Confederates, and was never delivered to the Treasury agents, the text found its way to the press, and Dix became one of the first heroes of the North during the Civil War. At the start of the American Civil War, Dix was appointed a major general in the New York Militia.

He served as the temporary chairman of the 1866 National Union Convention, was the United States Minister to France from 1866 to 1869, and served as the Governor of New York in his seventies  as one of the oldest governors of New York. Dix died in New York City and was interred in the Trinity Church Cemetery.

The Mississippi and Missouri Railroad (M&M Railroad) was the first railroad in Iowa and was chartered in 1853 to build a line between Davenport, Iowa, on the Mississippi River and Council Bluffs, Iowa, on the Missouri River and played an important role in the construction of the First Transcontinental Railroad.

The line was originally created so that the Chicago and Rock Island Railroad could extend its line across the Mississippi River via Government Bridge, the first bridge to cross the Mississippi.

Shortly after the bridge opened in 1856, a steamboat hit the bridge and steamboat companies sued to have the bridge dismantled. The M&M and Rock Island hired private attorney Abraham Lincoln to defend the bridge. The case was to work its way through the courts to reach U.S. Supreme Court in 1862 during the American Civil War when the court decided in the bridge's favor.

During Lincoln's investigation into the case ,he traveled to Council Bluffs to inspect M&M property in August 1859 under the guidance of the M&M attorney Norman Judd. On the visit Judd and M&M engineer Grenville Dodge described the merits of locating the eastern terminus of the railroad at Council Bluffs. After the Pacific Railroad Act in 1862, Lincoln selected Council Bluffs as the eastern terminus and the Union Pacific created by former M&M owner Thomas C. Durant as the company to build the railroad road eastward.

Durant was slow to build the M&M through Iowa although quick to manipulate its stock. He had gained control of the Union Pacific because of his stated plans for the M&M. However, the line under his ownership did not even make it half way across the state, terminating in Kellogg, Iowa, 40 miles (64 km) east of Des Moines, Iowa, in 1865 with a branch to Muscatine, Iowa, ending in Washington, Iowa.

Durant built up his fortune by manipulating the M&M stock via rumors. First he drove up M&M stock by saying the transcontinental railroad would travel across Iowa via the M&M while at the same time quietly buying depressed Cedar Rapids and Missouri Railroad (CR&M) stock. Then he spread rumors that drove up the CR&M stock that the transcontinental would follow that line instead and Durant bought back the newly depressed M&M stock. The gambit made Durant and his cohorts $5 million.

The Rock Island Line bought the M&M on July 9, 1866, and completed its line to Council Bluffs in 1869 and extended the Muscatine/Washington Line to Leavenworth, Kansas. The merged railroad was called the Chicago, Rock Island and Pacific Railroad, a name it kept until it was dissolved in bankruptcy in the 1970s.

Samuel Sloan (December 25, 1817 – September 22, 1907) was an American politician, businessman and executive. He is most known for his tenure as the president of the Delaware, Lackawanna & Western Railroad (DL&W) for 32 years.

Samuel Sloan was born in Lisburn, County Down, Ireland to William and Elizabeth Sloan and moved to New York when he was one year old. He attended the Columbia College Preparatory school until he was 14, at the time of his father's death. After withdrawing, he became employed at an importing house in New York, eventually becoming the head of the firm.

Sloan was elected as a Supervisor in Kings County (Brooklyn) in 1852, and was president of the Long Island College Hospital. He became a director of the Hudson River Railroad in 1855, left the importing business in 1857 and was elected to the New York State Senate, where he served for two years.

He became a director of the Delaware, Lackawanna & Western Railroad in 1864, and became its president in 1867. Prior to accepting the DL&W Presidency, Sloan had declined an offer to become President of the New York and Harlem Railroad. He extended the DL&W rail lines, and the company achieved great success, in part due to the traffic generated for transport of anthracite coal mined in the railway's expanded territory. Passenger traffic also increased, particularly between New York City and the Pocono Mountains in Pennsylvania, a popular resort area.

Sloan resigned from the DL&W presidency in 1899, but continued as Chairman of the Board. He served on the boards of banks, utilities and other companies.

On April 8, 1844, Sloan married Margaret Elmendorf in New Brunswick, New Jersey, and moved to Brooklyn, New York. Margaret was a daughter of Peter Zabriskie Elmendorf and Maria La Grange (née Van Vechten) Elmendorf. They had eleven children, including:

• Peter Elmendorf Sloan (1845–1916), who graduated from West Point in 1865.
• Maria LaGrange Sloan (1847–1929), who married Edgar Stirling Auchincloss (1847–1892), parents of U.S. Representative James C. Auchincloss.
• Margaret Elmendorf Sloan (1854–1906), who married the Rev. Joseph Rankin Duryee (1853–1935) in 1883.
• William Simpson Sloan (1859–1896), who married Julia Rapallo (1862–1935).
• Elizabeth LaGrange Sloan (1862–1960), who married Joseph Walker Jr. (1858–1927), senior partner and president of the investment banking firm of Joseph Walker & Sons, in 1887.
• Samuel Sloan Jr. (1864–1939), a banker with Farmers' Loan and Trust Company who married Katherine Colt and inherited Oulagisket.
• Mary Adelaide Sloan (1868–1954), who married Richard Collins Colt (1863–1938), parents of banker S. Sloan Colt.

Sloan died in Garrison, New York, in 1907 at the age of 89, having been the president of seventeen corporations during his lifetime.

Samuel Sloan is the eponym of the city of Sloan, Iowa and the village of Sloan, New York.

Upon his daughter Margaret's 1883 marriage, he built "Wyndune" in Garrison as a wedding present for them near his own Garrison estate known as Oulagisket (later renamed Lisburne Grange by his son). Similarly, upon his daughter Elizabeth's 1887 marriage, he built "Walker House" in Garrison for them.

A statue memorializing Sloan was placed in Hoboken, New Jersey, originally facing the ferries in 1899. Some people criticized the statue's orientation, and the Mayor of Hoboken remarked that Sloan was "turning his back on the great city of Hoboken." On August 3, 1908, during the reconstruction of Hoboken Terminal, the statue was set facing both the town and the railroad and ferry stations.
