After graduating from college, Seward served as a
secretary to his father from 1849 to 1857, and served as associate editor of the
Albany Evening Journal from 1851 to 1861.
Baltimore Plot 1861–1865 On February 21, 1861, Seward arrived at the Continental Hotel in
Philadelphia carrying a letter from his father for President-elect Lincoln. The letter contained information gathered by Colonel
Charles Pomeroy Stone and General
Winfield Scott. Stone had stationed three detectives from the New York police department in
Baltimore to gather information about plots against Lincoln. Making his way by train from Illinois to Washington for his inauguration, Lincoln had intended to stop next at Baltimore, which was home to many
secessionist sympathizers. According to information gathered by Stone's detectives, secessionists were planning to assassinate Lincoln during his stop in Baltimore. The warning Fred Seward brought would contribute to Lincoln's decision to pass through Baltimore under the cover of night, rather than stop and appear in public there. Although
Allan Pinkerton also warned Lincoln of danger awaiting him in Baltimore, it was Seward's information that confirmed everyone's fears.
Civil War When his father was appointed
Secretary of State in 1861, Seward became Assistant Secretary of State in charge of consular service under Lincoln and
Andrew Johnson. He served in the position until 1869 and "assisted in the negotiations to the adoption of the
Burlingame Treaty," which set the attitude towards China when the empire "accepted the principles of international law." On April 17, 1868, Seward
testified in
the impeachment trial of President
Andrew Johnson, having been called as a
witness by Johnson's defense team. Frederick's father died on October 10, 1872. Seward was a member of the
New York State Assembly (New York Co., 7th D.) in
1875. At the
New York state election, 1875, he ran on the Republican ticket for
Secretary of State of New York, but was defeated by Democrat
John Bigelow. He served again as
Assistant Secretary of State, in the administration of
Rutherford B. Hayes under
William M. Evarts, from 1877 until his resignation in November 1879 due to illness. Seward also edited and published his father's
autobiography and letters in a volume entitled
Life and Letters of William H. Seward. Mostly, his life after 1881 was devoted to the practice of his legal profession and to lecturing and writing. ==Personal life==
