The 1st Lord Tweedsmuir, John Buchan, was born on August 26, 1875. Buchan's contributions to Walter Scott study have been noted in a post on his date of death. Buchan was born in Perth, Scotland, and included much of Scotland in his works. In particular, the Upper Tweed Valley/Borderlands that inspired Sir Walter Scott.
