Samuel Rufus Rosoff (12 May 1881 – 9 April 1951) was a Russian-born American construction contractor and businessman who became one of the most prominent figureheads of the New York City subway expansion era during the 1920s and 1930s..

Rising from poverty as a young immigrant newsboy, Rosoff secured more than $40 million in municipal engineering contracts. His firms excavated significant underground segments of the Independent Subway System (IND) and the Sixth Avenue Line, earning him the widespread press moniker "Subway Sam".

Later in his career, he expanded his business portfolio internationally into Mexican rail lines and domestic water infrastructure projects.

Early life

Rosoff was born in Minsk, Russian Empire, to a Jewish family on 12 May 1881.

Following the death of his father, he emigrated to England at age nine, working briefly as a cabin boy before arriving in New York City around 1892.

As a youth, he lived in severe poverty in lower Manhattan, working as a newsboy on Park Row and sleeping on sidewalk gratings. He later secured work as a "candy butcher" on the West Shore Railroad and relocated temporarily to the Adirondacks, where he received his first exposure to structural logistics working on a regional lumber railroad.

By his early twenties, he began operating independently as a minor contractor, purchasing abandoned rail lines for scrap and bidding on local road building projects across upstate New York.

Subway construction and expansions

Rosoff's career shifted dramatically in 1925 when his small contracting company entered a low bid of $4.6 million for the Washington Heights section of the Independent Subway System (IND), running beneath St. Nicholas Avenue between 122nd and 133rd Streets.

Backed financially by Edward Staats Luther, who countersigned the operational checks alongside Rosoff's wife, Rose Price Rosoff, the project was completed nearly a year ahead of its municipal schedule.

Rosoff revolutionized large-scale underground excavation by introducing heavy motor shovels directly into the tunnel cuts and deploying advanced belt-conveyor systems to accelerate dirt extraction. His company subsequently won major tunneling awards, including sections under Eighth Avenue and a massive $14 million contract stretching from Third Street to Park Place.

By 1936, his cumulative New York transit contracts exceeded $40 million, establishing him as one of the most prolific subway builders in the city's history. In October 1935, his firm secured the highly contested Sixth Avenue Line construction contract under an island-filling infrastructure option.

Commercial ventures and international bids

Beyond New York City municipal transit, Rosoff aggressively diversified his corporate assets. In 1929, he purchased the bankrupt Delaware & Northern Railroad (D&N) for $70,000.

That same year, a delegation led by Valery Mezhlauk, vice-president of the Soviet Supreme Council on National Economy, arrived in New York to negotiate a projected $175 million contract for Rosoff to construct the Moscow subway and municipal waterworks system.

After traveling to the Soviet Union via the steamer Berengaria to inspect the local terrain, Rosoff publicly declined the contract in July 1929, citing a lack of international financial guarantees and credit backing from American banking institutions.

In 1935, Rosoff outbid competitors at a public bankruptcy sale to purchase the assets of the historic Hudson River Navigation Corp. (widely known as the Night Line) for $100,100, assuming immediate control of its major river transport steamers, including the Berkshire

During the pre-war era, Rosoff bid successfully on a $47 million contract to build a third set of locks for the Panama Canal, though the project was ultimately canceled due to the outbreak of World War II.

In 1947, his firm won a $9 million contract to excavate a seven-mile-long municipal water tunnel under the city of Baltimore, Maryland. Concurrently, he expanded operations into Latin America, completing a $10 million aqueduct in Puebla for the Mexican government, acquiring a massive lumber interest in Chihuahua, and buying controlling interest in the 500-mile-long Mexico North-Western Railway.

Public persona and legal disputes

Rosoff was widely recognized for his boisterous personality, public gambling habits, and his preference for inspecting active, muddy construction cuts while dressed in formal evening wear. Despite his lack of formal schooling, he regularly brushed off criticisms regarding his literacy by stating that he could easily hire university graduates to execute the technical paperwork.

His career was occasionally marked by labor disputes and political controversies. He maintained close ties with Tammany Hall politicians to secure municipal positioning.

In February 1937, he was briefly detained by law enforcement as a material witness following the high-profile union slaying of R. Norman Redwood. Furthermore, his corporate operations faced various civil liability trials, most notably the landmark New York appellate premises case Diglio v. Rosoff Subway Construction Company (1934).

Rosoff was a keen gambler and a regular at the high-stakes poker and dice games staged by Arnold Rothstein and other professional gamblers in the New York area. On one occasion, he is reported to have lost $100,000 in a single game and handed over a shoebox containing the money.

Death and legacy

Rosoff was admitted to Johns Hopkins Hospital in Baltimore, Maryland, on 1 April 1951. He died on 9 April 1951, at the age of 68, following an operation for a severe intestinal ailment.

His body was returned to New York and interred at Union Field Cemetery in Queens. He was survived by his wife, Rose, and his two sons, Nathaniel and Stanley.
