LR^{2}H
Robert Rinehart (19081985), professor at Case Institute of Technology, was successful as an applied mathematician. He published twentyfive papers in mathematics and operations research plus was a Russian translator for scientific societies.
Yet, he must have had a flair for mathematical humor. In April 1958, he gave the conference talk "The Modern Approach to LR^{2}H" to the Ohio section (MAA). So how is this a sign of humor?
The talk's description: "How writers of literature might impart new austerityand hence beautyinto their works by employing modern mathematical language was illustrated by discussion of the story of Little Red Riding Hood (LR^{2}H) in modern mathematical parlance...the grandmother, G, could be denoted by f(f(LR^{2}H)), where f is the Murrow mapping..."daughter" → "mother."
If you can appreciate higherlevel math humor, then read a written version of his talk (Mathematics Magazine, Jan 1959, pp. 151152). It will make you laugh!
