Leonard Roth

Not to be confused with Klaus Roth.

Leonard Roth (29 August 1904 Edmonton, London, England – 28 November 1968 Pittsburgh, Pennsylvania) was a mathematician working in the Italian school of algebraic geometry. He introduced an example of a unirational variety that was not rational (though his proof that it was not rational was incomplete).

His sister was Queenie Roth, literary critic and wife of F. R. Leavis.
