He was employed as engrossing clerk and assistant journal clerk in the
state capitol at
Albany, New York, was a clerk on the staff of the
Democratic state central committee in 1872 and was chief clerk of the New York department of state from 1875 to 1882. In 1883, through his mentor
Daniel Manning, Lamont was assigned to then-
New York Governor Grover Cleveland's staff as a political prompter. He became private and military secretary with the honorary rank of colonel on the governor's staff the same year and continued in his service after Cleveland became president in 1885. Lamont also held employment with
William C. Whitney in his business ventures in 1889. From March 5, 1893, to March 5, 1897, Lamont served as United States
Secretary of War in President Cleveland's cabinet. Throughout his tenure, he urged the adoption of a three-battalion infantry regiment as a part of a general modernization and strengthening of the
Army. Furthermore, Lamont recommended the construction of a central hall of records to house Army archives and urged that
Congress authorize the marking of important battlefields in the manner adopted for
Antietam. He also recommended that lands being used by
Apache prisoners at
Fort Sill be acquired for their permanent use and their prisoner status be terminated.
Later life After his service as Secretary of War, Lamont was vice president of the
Northern Pacific Railway Company from 1898 to 1904. He was also a director of numerous banks and corporations. In 1889, he went into business with
William C. Whitney (Cleveland's
Secretary of the Navy) and
Oliver Hazard Payne (organizer of the
American Tobacco trust). In August 1904, he was considered as a candidate for
Governor of New York, with
The New York Times writing "Qualifying experience in large public and private affairs, ability and executive capacity already demonstrated in high office, and personal character quite above all impeachment or assault unmistakably designate Daniel S. Lamont as a fit candidate for the Democrats of New York to name for the Governorship." ==Personal life==
