In 1988 his work was exhibited at the David Winton Bell Gallery at Brown University.Mathemagic: Magic Squares and Other Designs By Royal Vale Heath David Winton Bell Gallery. August-Sep, 1988
Heath played a crucial role in the career of popular mathematics writer Martin Gardner. At a magic show in 1956 he introduced Gardner to flexagons and these folded paper shapes became the subject of Gardner's December 1956 column in Scientific American which launched his quarter century tenure there.The Colossal Book of Mathematics: Classic Puzzles, Paradoxes, and Problems by Martin Gardner, W.W. Norton & Company (2001), , p.395The name "Mathematical Games" was not applied to Gardner's column until the following month: but the flexagon column was in all but name the first in the series of almost 300 columns which followed under that name. Several of Heath's tricks have been collected in Gardner book Mathematics, Magic and Mystery.Gardner, Martin Mathematics, Magic and Mystery Dover (1956),
