In 1812, he was elected the first president of the newly formed City Bank of New York, which later became Citibank, predecessor of today's Citigroup.

He joined the local militia, was elected to represent the town in the colonial assembly, and in 1775 to the provincial congress that functioned as a revolutionary government.

[4] During the American Revolution, Osgood led a local company of minutemen into the Battle of Lexington and Concord in the spring of 1775.

[5] After a brief term in the Massachusetts House of Representatives in 1784, the governor appointed Osgood a judge in 1785 but he soon resigned when the National Congress made him a commissioner of the Treasury later that year.

[8] One of the first things Osgood would do is make the Post Office in Baltimore the new regional headquarters, whose postmaster was Mary Katherine Goddard.

Osgood offered the mansion to Washington so that the President and his wife would have what was then considered the finest house in the city as their home.

[2] When the Federal Government moved to Philadelphia for a ten-year period before finally settling in Washington, D.C., Osgood chose to remain in New York and resigned his post in 1791.

In 1803, he was appointed by President Thomas Jefferson as Naval Officer of the Port of New York, a position he held until his death.

His birthplace in North Andover, Massachusetts, is located on a street named for his family, and is listed on the National Register of Historic Places, as is his New York residence.
