“Leonard carried out extensive research on carbon materials, using electron spin resonance to elucidate the role of free radicals in the conversion of precursors to carbon and graphite. In 1970, he produced the first mesophase-pitch-based graphite fibers, which are now commercially produced for use in aerospace, military, and consumer ­applications. This achievement was recognized as a National Chemical Historical Landmark in 2003. Leonard was also passionate about music, serving as choir director of his temple and as clarinet player and part-time director of the Union Carbide Parma Technical Center dance band.”—Helen Mayer, colleague
