Early Life and Education Abraham Riker Lawrence was born in New Hackensack, Dutchess County, New York. He received a classical education and graduated from Columbia College in 1797. After college he entered the mercantile profession, training in the New York store of Lieutenant Governor John Broome.

Business Career In 1801 he entered into business with his cousin, John Lawrence, and remained in that partnership for ten years. He subsequently formed a business with his youngest brother, William T. Lawrence. His commercial experience brought him into contact with influential political and financial figures of the early nineteenth century.

Public Service and Political Activity Abraham became active in the Democratic-Republican Party during the era in which James Madison and George Clinton represented competing visions for the young nation. In 1812, when the non-importation laws threatened to ruin New York merchants, Lawrence joined Washington Irving and others to petition Congress for relief. In 1818 he was appointed appraiser of imported goods for the federal government, responsible for detecting violations of customs laws.

Railroad and Municipal Leadership In 1836 Lawrence was elected president of the New York and Harlem Railroad Company. During his administration, the line was extended from City Hall to the Harlem River, laying an early foundation for the city’s rail infrastructure. In 1847 he entered municipal government as Alderman of the 8th Ward, continuing the family’s long tradition of civic involvement.
