John Leyden and Sir Walter Scott

In 1801 Heber introduced Leyden to Walter Scott, whom he materially helped with the earlier volumes of the Border Minstrelsy (1802), contributing five poems to volume 1 and material for the learned disquisition on fairies to volume 2 (Lockhart, 1.326). ... Scott, in addition to frequent references, embalmed his ‘bright and brief career’ in the Lord of the Isles, IV.xi. His ‘Memoir of Leyden’ first appeared in the Edinburgh Annual Register (1811). (ODNB)
