John, his father and his brother George, Jr performed the original survey of Pittsburgh.
The survey established the future boundaries of Pittsburgh including a tract called "John Woods Plan".
With Hugh Brackentidge and Alexander Addison, Woods controlled the legal system in Pittsburgh from 1788 until the mid-1790s.
His earlier political career included serving as a presidential elector, and he was a five-time candidate for Congress prior to his successful election in 1814: in 1791[4], 1794[5], 1796[6], 1798[2], and 1812[7].
The term was set to run until March 3, 1817, but Woods never appeared in Congress due to poor health.
