Samuel Zygmuntowicz was already a prize-winning sculptor before beginning his instrument-making studies at age 13.

Since 1985 he has made instruments by advance commission for performers such as Cho-Liang Lin, Joshua Bell, Maxim Vengerov, Yo-Yo Ma, and the entire Emerson String Quartet. A 1994 violin that he made for Isaac Stern still holds the record for the highest auction price paid for a musical instrument by a living maker. The Harper Collins book THE VIOLINMAKER documents the making of a violin for Eugene Drucker.

A graduate of the SLC Violinmaking School, he studied advanced making and restoration with Carl Becker and Rene Morel. His violins have won high honors in international competions.  His extensive studies of traditional violinmaking are often featured in THE STRAD magazine, and he teaches and works closely with acoustic researchers at the Violin Acoustics Workshops at Oberlin College. With physicist George Bissinger he collaborated on the first 3d laser vibration studies of Stradivari and Guarneri violins.

He has presented his findings throughout the USA including the  American Society of Acoustics, the Chamber Music Society of Lincoln Center and  the Juilliard School, and most recently at the E.G. Conference in Monterey CA;  and also presented internationally in Italy, Sweden, England,  Belgium,  and Australia.

Sam lives in Brooklyn NY, and still plays fiddle with a variety of performing folk music groups. His CD recordings include GRAND PICNIC and JUMP WHEN THE TRUMPETS BLOW.

George Bissinger Strad3D Acoustic Research Director

Dr. George Bissinger got into violin acoustics in 1969 following a chance meeting with Carleen Hutchins while a post-docto ral fellow at University of North Carolina-Chapel Hill where she was giving a colloquium. A second postdoctoral position, at Rutgers University in New Jersey, led to his working with Carleen from 1971 to 1990, and being exposed to all the most up-to-date violin research and many of the people doing it.

He broke from the traditional scientific approach to violins in the mid-1980s when the first modal analysis experiments on the violin were published. Because the violin behaves as a linear system completely describable in terms of normal modes, and these are completely determined by basic material properties, he realized that only the integration of normal mode measurements with computer-based simulations would allow us exploit the fundamental physics linking violin material shape and stiffness-density properties to dynamic behaviors. This linkage was the fundamental basis of the VIOCADEAS project (funded by the National Science Foundation) as a way to reverse-engineer the materials of legendary violins without requiring disassembly.

His work on violins to date: incorporating experimental and theoretical analysis of the two lowest acoustically important cavity modes A0 and A1, understanding the relative contributions of radiation from the f-holes and corpus, using structural acoustics experiments to understand the low-lying signature modes in the open string region and creating more statistical indicators at higher frequencies, analyzing the two major violin energy filters via modification of bridge dynamics (Oberlin Violin Acoustics Workshop) and vibration-sound energy conversion through the damping and critical frequency properties of a violin, discovering two new violin radiation mechanisms, and using CT scans to explore violin shape and density properties.

His normal mode violin research was performed at East Carolina University and since 1998 at its Acoustics Laboratory facility, which is unique in its ability to make zero-mass-loading, simultaneous vibration and radiation measurements in an anechoic chamber. To date 14 violins &enspace; all qualitatively rated -- and a complete violin octet are in the VIOCADEAS database.

In 2006 he organized the first 3-dimensional violin measurements of the renowned Titian and Willemotte Stradivari and Plowden Guarneri del Gesu violins, in a collaboration sponsored by the Violin Society of America with Polytec Inc. (who provided their scanning laser system and operating personnel), two renowned violin makers (for proper setup), CT scans at the Jenkins Cancer Center, and over-a-sphere far-field acoustic scans in the ECU anechoic chamber.

François Denis

Trained in science and music, François Denis set up his own business as an instrument maker in Angers, a town of the Loire Valley in France. Since 1988 he has devoted himself to violinmaking while continuing parallel in-depth studies on the history of this profession.

In 2000, he won the Musicora prize for his work. In 2006, he published the book TRAITE DE LUTHERIE, which shed new light on the origin of Stradivari's violin forms, and convincingly recreates the geometric design techniques of the classical period makers, based on proportion and ancient ratios. François Denis has given many lectures and courses in Europe and the U.S., focused on using this geometric design technique for new instruments.

John Topham Dendrochronology

John Topham trained as a violin maker in the Fachschule für Geigenbau, Mittenwald and graduated in 1971. He worked with Dietrich Kessler at the shop of Edward Withers Ltd in London and made and restored many instruments of the violin and viol families. In 1979 he became self-employed and moved to Surrey outside London. In 1985 he graduated with a Bachelor of Arts degree in mathematics and science at the Open University in the UK.

In 1995 he began work on dendrochronological methods to investigate instruments of the violin and viol families, as well as lutes, guitars, and clavichords. He and Derek McCormick have had two papers published in the Journal of Archaeological Science about work done on British and Italian instruments, the latter including the 1716 Antonio Stradivari violin known as the "Messiah". In 2007 he analyzed 20 Brescian instruments at an exhibition held in Brescia, and was asked by the American Federation of Violin and Bow Makers to examine 40 instruments attributed to be from Venice from 1680 to 1790 featured in an exhibition held in Boston.

He has also done dendrochronological examinations for the auctioneers Sotheby's and Bonhams in London, Christie's in New York and Skinners in Boston; for institutions such as the Musèe de la Musique in Paris and the Ashmolean Museum in Oxford; and companies such as J. & A. Beare Ltd in London, Bein & Fushi in Chicago and Schmitt in Lyon as well as many other dealers and musicians from the UK and other European countries. He is in contact with members of the dendrochronological laboratories at Sheffield University and Queen's University, Belfast, who have advised him in the acquisition and assessment of data from violins, He has now compiled a database comprising over 2,000 instruments, which has yielded nearly 4,000 sequences of data.

Eugene Schenkman   eschenkman@gmail.com

Eugene Schenkman has been in film and video production for the last seven years, since graduating from the Film and Television department at New York University Tisch School of the Arts. He has been playing the violin since the age of six. This, his latest film work, is part of a documentary probe into the world of violinmaking as refined art and important scientific endeavor. He strives to show the spiritual energy invested in crafting fine instruments and the intense commitment to acoustic research practiced by the new and heretofore largely unknown pioneers of the craft.

Eugene hopes that this work will shed greater light on the continuing drive by the featured violinmakers to share innovation with and inspire a new generation of acoustic instrument designers to reach beyond the enormous shadow cast by the great Cremonese masters of the past.

Video clips used for the Strad3D.org project are primarily chapters and vignettes derived from a larger piece that Eugene is preparing for major festival screenings and subsequent television distribution.

George Stoppani

George Stoppani inherited his Italian name from his Venetian grandfather, Pietro Faustino, who came to London in the early 1900s. George's father and mother were, respectively, a painter and a sculptress. George studied English and Related Literature at York University, graduating in 1972, but a few years on turned to instrument making. Circa 1977 he began an association with Northern Renaissance Instruments in Manchester where he developed an interest in historical matters and string making. He made a large number of period instruments but then began to make modern orchestral instruments as well.

Another more recent interest is modal analysis. This means taking measurements from assembled and strung-up instruments to see what actually happens when they vibrate. This has enormous potential for making instruments with superior playing qualities and for diagnosing problems on older instruments.

George has given talks at the Tiverton Conference (the fore-runner of the Dartington Conference) and has written articles for THE STRAD magazine, EARLY MUSIC TODAY, the BVMA newsletter and the CAS JOURNAL. He is on faculty at the Oberlin Acoustics Workshop, and has given many workshops and lectures on modal anaysis for violinmakers.
