free on the Internet Archive As a World War II WAC, Katharine Cornwell was involved in investigating the ENIAC computer for bomb survey analysis, which fueled her interest in mathematics. Bruce Cornwell did graphics work for a television station in Madison, WI, where he was also engaged with the local public radio station. The Cornwells were married in 1956. Bruce has stated that his interest in math films was influenced by his seeing Disney’s ‘Donald in Mathmagic Land,’ which prompted his comment "anyone with half a brain and one hand tied behind his back could make a better film." Like many other makers of quality academic film, the Cornwells found it made better financial sense to have additional careers. Katharine became a consultant specializing in executive compensation, while Bruce taught at Brooklyn Polytechnic. They live in Brooklyn. Filmography For Houghton Mifflin, the Cornwells, in conjunction with Duane W. Bailey, made a series called 'Calculus in Motion,' consisting of eight 3 minute, color, animated, silent 8mm loops. They were available as either Technicolor Magicartridges or Kodak Cassettes. They are: Functions, Limits, Derivatives, Concavity and Points of inflection, Rolle's Theorem and the Mean Value Theorem, The Definite Integral, The Fundamental Theorem, and Taylor Polynomials. For the Mathematical Association Of America in conjunction with Stanford University, a number of films were produced at the Cornwells' studio for the MAA Calculus series, under various directors. We do not have the names of most of these films, but among them are:
