After commencing practice in
Canandaigua, New York, in 1809, Spencer became a master of
chancery in 1811. During the
War of 1812, Spencer served in the
United States Army where he was appointed
brigade judge advocate general for the northern frontier. In 1826, Spencer served as a
special prosecutor to investigate the disappearance of
William Morgan who was arrested,
kidnapped and murdered for exposing secrets kept by
Freemasons, thus sparking the
Anti-Masonic movement. He moved to
Albany, New York in 1837.
Federal government In 1841,
President John Tyler appointed Spencer to be
Secretary of War in his administration. He also recommended that the government adhere to arrangements made by Army commanders in the field for compensation of the
Creek Indians, who had been forced to move west of the Mississippi. In 1842, his nineteen-year-old son,
Philip Spencer, a
midshipman, was executed without
court-martial along with two other sailors aboard the brig
USS Somers for allegedly attempting
mutiny. The expenditures of the treasury had exceeded its receipts and he advocated additional import duties on articles such as
coffee and
tea. To help fund the federal deficit he engaged in controversial issues of
Treasury Notes. He also continued to develop a plan, originally initiated by Forward, for a Board of
Exchequer to keep and disburse public funds raised by duties. The Exchequer bill, which reflected continuing interest in some form of independent treasury system, failed due to a political conflict in the
United States Congress. On two occasions in 1844, President Tyler nominated Spencer to fill open
Associate Justice seats on the
Supreme Court. The first failed attempt was in January, when Tyler put forward Spencer as a replacement for the recently deceased
Smith Thompson. Tyler made the nomination on January 9; on January 31, the Senate rejected Spencer by a 26–21 vote, mainly due to Whig opposition to the president. Tyler then nominated Spencer to fill
Henry Baldwin's seat in June but withdrew his name for that of
Reuben Hyde Walworth. As one of few northerners in an administration dominated by southern interests, Spencer had found it increasingly difficult to serve in his cabinet post and resigned as Treasury Secretary in May 1844. Thereafter, he returned to Albany. ==Personal life==
