About James Wilson
The law was his language. Consent was his principle.
Born near St Andrews, Scotland, in 1742, Wilson studied at St Andrews, Glasgow and Edinburgh before emigrating to America in 1765. He became a lawyer, political writer and Pennsylvania leader, then entered the Continental Congress.
He signed the Declaration of Independence, helped shape the Constitution at Philadelphia in 1787, and in 1789 became one of the first six justices appointed to the United States Supreme Court.
The identity and biography presented here refer specifically to James Wilson (1742–1798), the Pennsylvania delegate and jurist—not the many other people who share his name.
