Samuel Zygmuntowicz, Violinmaker, 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, Leila Josefowicz, David Finckle and the Emerson String Quartet members.
A 1994 violin that he made for Isaac Stern set a record for the highest auction price paid for a musical instrument by a living maker. The Harper Collins book THE VIOLINMAKER documents his making of a violin for Eugene Drucker.
He is a graduate of the SLC Violinmaking School, and studied advanced making and restoration with Carl Becker and Rene Morel. His faithful copies of classic violins won early acclaim, and he has designed many personal models as well.
In addition to his extensive studies of traditional violinmaking, often featured in THE STRAD magazine, he has worked closely with acoustic researchers and is often on staff at both the Violinmaking and Violin Acoustics Workshops at Oberlin College. With Strad3D, he has brought together an inspiring group of scientists, violinmakers, musicians, filmmakers and designers.
He has presented his findings throughout the USA, including The Chamber Music Society Of Lincoln Center, the Juilliard School, Friends of the St. Paul Chamber Orchestra, Music@Menlo and La Jolla Chamber Music festivals, plus conferences including the American Society of Acoustics, Arts and Science at CUNY, the E.G. Conference in Monterey CA, the Musical Instrument Museum in Pheonix AZ, and MOMATH in NYC, and presented internationally in Italy, Sweden, England, Belgium, Spain, Australia, and Canada, including the Banff International String Quartet Competition.
Sam lives in Brooklyn NY with his wife and two sons, and 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.
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.

ng Computed Tomography,(CT) since 1989 and has CT scanned several hundred instruments made by most of the important luthiers of the past.
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.
Joseph Curtin is a violinmaker, researcher, and 2005 MacArthur Fellow. Born in 1953 in Toronto, Canada, he began violin lessons at age 12, then went on to study violin at the University of Western Ontario, Literature and Philosophy at the University of Toronto, and viola performance with Rivka Golani.
In 1977, having concluded he would be neither happy nor successful as a professional musician, Curtin took up violinmaking under the guidance of the Hungarian maker Otto Erdesz. He finished his first instrument a year later, and subsequently worked as a maker in Toronto, Paris, and Cremona. In 1985 Curtin moved to Ann Arbor, Michigan, where he and Gregg T. Alf established the firm of Curtin & Alf. In 1997, Curtin opened his own studios.
Since the early 1990s, Curtin has pursued a strong interest in both violin acoustics and innovation. He has worked with many eminent scientists and researchers, including Charles Besnainou, Xavier Boutillon, Evan Davis, Colin Gough, Carleen Hutchins, Fan Tao, Thomas Rossing, Gabriel Weinreich, and Jim Woodhouse. Along with Fan Tao, Curtin is founder and co-director of the VSA Oberlin Acoustics Workshop, which brings violinmakers and researchers together annually for a week of talks and hands-on experimentation. Curtin is a frequent contributor to THE STRAD and STRINGS magazines. His papers on violin acoustics can be found in the VSA JOURNAL, VSA PAPERS, the CAS JOURNAL, and the PROCEEDINGS OF ISMA 98.

Eugene Schenkman email@example.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.

An avid string player, he has played violin in civic symphonies, folk dance bands, Celtic duos, and theatrical performances, and fiddle/mandolin/banjo/guitar in bluegrass bands,
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.

Violinist Cho-Liang Lin was born in Taiwan. A neighbor’s violin studies convinced the five-year-old boy to want the same musical toy. Thus began his music lessons. At the age of 12, he moved to Sydney to further his studies with Robert Pikler, a student of Janos Hubay. After playing for Itzhak Perlman in a master class, the 13-year-old boy decided that he must try to study with Mr. Perlman’s teacher, Dorothy DeLay. At the age of 15, Lin traveled alone to New York and auditioned for the Juilliard School and spent the next six years working with Ms. DeLay.
Lin’s concert career was launched in 1980 with his debut with the New York Philharmonic and Zubin Mehta. He has since performed as soloist with virtually every major orchestra in the world. His busy schedule continues to this day. However, his wide ranging interests have led him into diverse endeavors. At the age of 31, the Juilliard School invited Lin to join the faculty. In 2006 he was appointed professor at Rice University. He is currently music director of La Jolla SummerFest and the Hong Kong International Chamber Music Festival. Ever so keen about education, he ran a summer music camp and youth orchestra in Taiwan for four years.
In his various professional capacities Cho-Liang Lin has championed composers of our time. His efforts to commission new works have led a diverse field of composers to write for him. The list includes John Harbison, Christopher Rouse, Tan Dun, John Williams, Steven Stucky, Esa-Pekka Salonen, Bright Sheng, Paul Schoenfield, Joan Tower, and many more.
Lin performs on borth the 1715 Stradivari named “Titian” and a 2000 Samuel Zygmuntowicz. His many concerto, recital, and chamber music recordings can be heard on the Sony Classical, Decca, BIS, Delos, and Ondine labels. His albums have won Gramophone Record of the Year and Grammy nominations.
Violinist Aaron Boyd enjoys a versatile career as soloist, chamber musician, recording artist and teacher. Since beginning the violin at the age of 7, Mr. Boyd has concertized throughout the United States, Europe, Russia and Asia. Having played in nearly every major hall in New York City, Mr. Boyd was also a frequent guest artist at New York’s Bargemusic, where he appeared over 50 times. An avid chamber musician, Mr. Boyd has participated in the Marlboro, La Jolla, Bridgehampton, Prussia Cove and Tanglewood festivals and has collaborated with members of the Juilliard, Guarneri, and Orion Quartets, the Beaux Arts Trio, Phillippe Entremont, Mitsuko Uchida, Anner Bylsma, Siegfried Palm, Kim Kashkashian, and Gerard Poulet. Mr. Boyd toured and recorded internationally as a member of the Sejong Soloists and Manhattan Sinfonietta, and has played with the St. Paul, Orpheus, Metamorphosen and Prometheus Chamber Orchestras. Mr. Boyd has been a prizewinner in numerous competitions including the Ecoles D’art Americaines de Fontainebleau, the Klein Violin Competition, the Tuesday Music Society and the Pittsburgh Concert Society and was awarded a Proclamation by the City of Pittsburgh for his musical accomplishments.
Mr. Boyd recently joined the Escher of Columbia University and plays a violin crafted in 2002 by Samuel Zygmuntowicz, and a 18th century violin by Mateo Goffriller.
Christopher Reuning, a violin maker, restorer and expert, grew up in a musical family and he began playing cello at the age of seven. He began as a violin making apprentice at the age of twelve at the House of Primavera in Philadelphia, Pennsylvania. For the next six years, to supplement his Philadelphia training, he frequently traveled to Cremona, Italy to work with Virgilio Capellini. During those years he began to develop a close association with the important experts in violin identification Dario D'Attili and, later, Charles Beare.
Christopher has been director of Reuning & Son Violins since 1978 and purchased the business from his parents in 1984. In 1994, he moved the business to its current location in Boston, Massachusetts.
Christopher takes special interest in researching the history of the old master violin makers and the identification of old violins. He also tries to find enough time at the workbench to have a restoration project in progress as well as occasionally making a violin.
Christopher is Vice-President of the American Federation of Violin and Bow Makers, an advisor to The North Bennett Street School Violin Making Department, on the board of The Boston Chamber Music Society, and also co-founded Tarisio Auctions in 1999, which now leads the industry in market share.
He also still finds time to enjoying performing and is a member of the Longwood Symphony Orchestra. He is the father of two daughters, Gretchen and Monica, of whom, in spite of their being wind players, he is exceedingly proud.
