US 1790 to 2006 Annual GDP & GDP Per Capita - both Nominal & Adjusted for Inflation

Below is a table of annual GDP data for the United States that I have shamelessly stolen from Wikipedia. I am rather irritated that it has taken me as long as it did to find historical GDP data going back before the 80's. Why this is a massive challenge (as in the OECD, IMF and World Bank websites have no easily accessible historical GDP data) in 2016 is beyond me.

Anyway.
