On this day 250 years ago in Philadelphia, James Cannon, an immigrant from Scotland, became a member of the Constitutional Convention of Pennsylvania, and was put in charge of drafting the instructions for Pennsylvania’s delegates to Congress. The Convention also made him a Justice of the Peace for the state of Pennsylvania, and appointed him to serve as a member of the Council of Safety from July 24, 1776 to December 4, 1777. Cannon
is regarded as one of the two principal draftsmen of

the Pennsylvania Constitution of 1776, the most progressive state constitution of the Revolution.
