Dr John Sampson (1862-1931) was the first Librarian at University College (later University of) Liverpool, from 1892-1928. In 1907 John Sampson and fellow gypsiologist David MacRitchie persuaded Robert Andrew Scott Macfie to revive the Gypsy Lore Society which had been defunct for the previous 14 years. Sampson was President of the Gypsy Lore Society 1915-1916.

John Sampson was the author of The dialect of the Gypsies of Wales: being the older form of British Romani preserved in the speech of the clan of Abram Wood (Oxford University Press, 1926) and of A hundred Shelta sayings (Gypsy Lore Society, 1908).
