Chicago and Canada Southern Railway Co. Signed by Sidney Dillon and transferred to W.H. Vanderbilt - 1878 dated Autographed Stock Certificate

Sidney Dillon (May 7, 1812 – June 9, 1892) was a prominent American railroad executive and financier who rose from humble beginnings to become one of the leading railroad builders in the United States. Born in Fulton, New York, to a farming family, Dillon entered the rail industry as a young water boy on the Mohawk and Hudson Railroad, one of the nation’s earliest rail lines. By 1840, he had established his own construction company and secured a significant contract for the Boston and Albany Railroad. His sharp business acumen and relentless drive propelled him through the ranks of the rapidly expanding American transit network, solidifying his position as a key contractor for major East Coast lines.

Dillon’s defining legacy emerged through his substantial investment and active involvement with the Union Pacific Railroad, beginning in 1865. He played a crucial role in constructing the First Transcontinental Railroad and was present at Promontory Summit, Utah, for the historic driving of the Golden Spike in 1869. Dillon later served two terms as the president of Union Pacific (1874–1884 and 1890–1892) and held the position of director for the Western Union Telegraph Company. While his legacy faced scrutiny due to his association with the Crédit Mobilier of America scandal, his monumental impact on American infrastructure remains permanently commemorated by towns named in his honor, including Dillon, Montana, and Sidney, Nebraska.

Charles D. Lanier (January 19, 1837 – March 6, 1926) was an American banker, and railroad executive who inherited the bulk of his father's fortune, who was a close friend of J.P. Morgan. In 1859, he joined his father in the family banking establishment, Winslow, Lanier & Co., that was founded in 1849 with Richard H. Winslow. He was given an interest in 1860, and later became head of the firm. The younger Lanier worked continuously at Winslow, Lanier & Co. for sixty-seven years, one of the longest careers in banking at that time.

He served on the boards of the Southern Railway, the Pittsburgh, Fort Wayne & Chicago Railway (of which he was president and his father was the first president), Massillon & Cleveland Railroad, and a trustee of the Central Union Trust Company. In addition, he was a director of the Central Railroad of New Jersey, the West Shore Railroad, the Western Union Telegraph Co., The Central & South American Telegraph Co., the Madison Square Garden Co., and the National Bank of Commerce.

Lanier was a close friend of fellow banker J.P. Morgan, and the two worked together on many of the largest and most important transactions of the day. Lanier was part of the small group, known as the "Corsair Club," as it met on Morgan's yacht, the ‘’Corsair’’.
