Marcus Daly (December 5, 1841 – November 12, 1900) was an Irish-born American businessman known as one of the three "Copper Kings" of Butte, Montana, United States.
Daly emigrated from County Cavan Ireland to the United States as a young boy, arriving in New York City. He sold news papers and worked his way to California in time to join the gold rush on what was to become Virginia City, Nevada and the fabulously rich silver diggings now known as the Comstock Lode, in 1860.
Marcus Daly gained experience in the mines of the Comstock under the direction of John William Mackay and James G. Fair. While working in the mines of Virginia City, Daly met and befriended George Hearst and Lloyd Tevis, co-owners of the Ophir Mining Company. (George Hearst was the father of William Randolph Hearst). In 1872, Daly would recommend purchase by the Hearst group the Ontario mine, in Lake Flat, Utah. In ten years, the Ontario produced $17 million and paid $6,250,000 in dividends. That purchase made many millions for Hearst and Haggin. Their business friendship was to extend for many years and help establish the Anaconda Copper Mine in Butte, Montana. Daly originally came to Butte in August 1876 to look at a mine, the Alice, as an agent for the Walker Bros. of Salt Lake City. The Walkers purchased the mine, installed Daly as Superintendent and awarded him a fractional share of the mine.
Marcus Daly (September 18, 1908 – July 25, 1969) was an American Republican Party politician, who served on the Monmouth County Board of Chosen Freeholders from January 2, 1963 to his death on July 25, 1968, and was a 1964 candidate for the United States House of Representatives.
Freeholder Daly was born in Long Branch, New Jersey.
He was a 1930 graduate of Georgetown University School of Foreign Service. He studied law at St. John's College in Brooklyn, New York and insurance at New York University. He received a Master's Degree in Political Science from Columbia University in 1949, and studied International Law at the Hague Academy of International Law. In 1961 he was awarded the title of Professor Extraordinary from the Pontifical University of Colombia. He had been on the faculty of Fordham University and was a professor of political science at St. Peter's College in Jersey City, New Jersey.
Daly received the Grand Croix of Merit avec Plaque and Cordon of the Sovereign Military Order of Malta in 1961 for his work in international social welfare.
