Murray Campbell

(b Cleveland, OH, July 19, 1915; d Pittsburgh, PA, Feb 10, 2010). American scientist and acoustician. After studying physics at Case Institute of Technology (BS 1937), he carried out research in nuclear physics at the University of Illinois (PhD 1941). He then joined the Westinghouse Electric Corporation, remaining with the firm for the rest of his professional life; he retired in 1980 after a distinguished career culminating in six years as Director of Research and Development. In his youth he had become an accomplished flute player, and during his undergraduate studies at Case he encountered the notable acoustician Dayton C. Miller. This meeting led to a lifelong interest in the acoustics of the flute, and Coltman developed a laboratory at his home in which he conducted many important and illuminating experiments on flutes and flute playing. Particularly significant was his contribution to the understanding of the subtle interaction between the air jet blown across the flute embouchure hole by the player and the resonances of the air column within the flute pipe. Over four decades, starting in the mid-1960s, he published more than 40 papers on the acoustics of flutes and organ pipes. He was a member of the National Academy of Engineering and a Fellow of the American Physical Society and the Institute of Electrical and Electronic Engineers....

D. Quincy Whitney

(b Springfield, MA, May 24, 1911; d Wolfeboro, NH, Aug 7, 2009). American violinmaker, acoustician, and writer. A trumpeter and biology graduate of Cornell University (AB 1933) and New York University (MA 1942), she left both disciplines to embrace string instruments and acoustical physics. While teaching science and woodworking at the Brearley School, chamber music colleagues convinced her to take up viola. A woodcarver since childhood, Hutchins, at age 35, decided to make a viola. Hutchins then studied luthiery with Karl A. Berger (1949–59) and Stradivari expert Fernando Sacconi. While she and Harvard physicist Frederick A. Saunders performed more than 100 acoustical experiments (1949–63), Hutchins taught herself acoustical physics by making string instruments. In 1963 Hutchins and colleagues Robert Fryxell and John Schelleng founded the Catgut Acoustical Society. She published the CAS journal for more than 30 years, helping bridge the gap between violin makers and acoustical physicists. Hutchins made more than 500 instruments, authored more than 100 technical papers on violin acoustics, and edited ...
