Daniel Gray Reid (August 1, 1858 – January 17, 1925) was an American industrialist and philanthropist known as the "Tinplate King".
He was born August 1858 in Richmond, Indiana, and is a son of Daniel and Anna (Dougan) Reid. Reid was educated in the public schools of Richmond. His father died when he was 15 years old and he was reared by his mother. At the age of seventeen he entered the Second National Bank as messenger boy, obtained his business training there and gradually won promotion until he was made teller, which position he resigned in 1895. In 1892, he became interested in the American Tin Plate Company, owners of an extensive plant at Elwood, Indiana. He and his partner, William B. Leeds, another Richmond native, bought the tin plate mill, with which he eventually combined every tin plate company in the country to form the American Tin Plate Company, with Reid as president. In 1901, J. P. Morgan included the tinplate trust in the giant steel trust, United States Steel Corporation, and reportedly paid $18 million for the company and Reid became the director. He bought control of the American Can Company and the Chicago, Rock Island & Pacific Railroad. In 1912, he organized the Tobacco Products Corporation with Henry Clay Frick, John D. Ryan and others.
On October 13, 1880, Reid married Miss Ella C. Dunn, of Richmond, Indiana. Mrs. Reid died on the 25th of June, 1899 in Chicago. His daughter Rhea married Henry J. Topping, the son of Republic Iron and Steel president, John A. Topping.
Reid married two more times after her death. In 1900, he married his second wife, actress Miss Clarice Agnew whom The New York Times labeled “a theatrical beauty.” They moved into a mansion on Fifth Avenue across from Central Park with his daughter where the needs of family were taken care of by 20 live-in servants. She died in 1904. Then in 1906, he married his third wife, former actress Margaret M. Carrere who had appeared in "The Chinese Honeymoon, "The Runaways" and "West Point Cadet". Reid filed for divorce in New York in May 1919 on grounds of infidelity. Later, Reid abandoned the charges but his wife filed a counterclaim against him and won. They were divorced in February 1920.
