(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 ...

Anne Beetem Acker
(b Bermuda, July 10, 1957). American audio engineer, musician, and owner of Keith McMillen Instruments, based in Berkeley, California. He received his BS in acoustics from the University of Illinois, where he also studied classical guitar and composition. In 1979 he founded Zeta Music, which designed and sold electric and electronic violins and basses. In 1992 he organized a research laboratory for Gibson Guitars. He developed a computerized composition, notation, and performance system, and also helped devise ZIPI, a MIDI-like music control language. At the Center for New Music and Audio Technologies at the University of California, Berkeley, he researched audio networking, synthesizers, and string instruments. In 1996 he became director of engineering for the audio processing and distributed music networks division of Harmon Kardon. In 1999 he founded Octiv, Inc., an Internet audio signal processing company, which produced the ‘Volume Logic’ plug-in for iTunes that allows digital audio remastering to improve the sound produced by computers and MP3 players....
Mark D. Porcaro
(b New York, NY, May 23, 1934; d Asheville, NC, Aug 21, 2005). American designer of electronic instruments. He became interested in electronics during his teens after encountering the theremin. While in high school he provided schematics and descriptions of his own theremin for Electronics World, a hobbyist magazine. After graduating in 1952 he started the R.A. Moog Co. with his father’s help to create and sell mail-order theremin kits from his home. Moog studied physics at Queens College, New York, electrical engineering at Columbia University, and graduated in 1965 with a PhD in engineering physics from Cornell University.
In 1964 Moog worked with the composer Herb Deutsch to create a monophonic synthesizer consisting of a variety of modules of voltage-controlled oscillators, amplifiers, envelope generators, and filters linked together by patch chords and controlled by a keyboard. The Moog synthesizer was the first to use Vladimir Ussachevsky’s envelope generator—known as an attack, decay, sustain, and release envelope—which could shape the timbre of a pitch by modifying its amplitude over time. Moog demonstrated his new instrument at a convention that year for the Audio Engineering Society, where he also took the first orders for his new instrument....
