Kashnor, Leon.

Together with his brother D. Kashnor, Leon Kashnor was the owner of the Museum Book Store in London specializing in social and economic history; he was among the first booksellers to gather a large collection around some movement or person, before selling it as a whole; in the course of forty years he built up and sold several collections of unique material relating to British social and economic (and political) history from the seventeenth century on; a collection of this kind, including the workers' and socialist movement, was acquired by the IISH in 1937.
