Leading the world in Advanced Composite Training
In the November 2012 issue of HPC, we
reported on the use of carbon fiber in
the manufacture of carbon fiber musical instruments, including violins, cellos
and guitars. The article included a review
of the history of carbon fiber in instruments. Unfortunately, we overlooked one
major contributor.
Leonard K. John, senior engineering
advisor, materials technology, at Bombardier (Toronto, Ontario, Canada), reports that he developed the world's first
carbon fiber violin in the 1970s, and in
1983 he was granted the first U.S. patent for a carbon fiber violin and related
instruments, including the viola, cello
and bass. John tells HPC that he has produced nine violins to date, with a 10th under consideration.
John's original carbon fiber violin is on display at the Ontario Science Center in Toronto. His instrument also is on display at the National Music Museum at the University of South
Dakota (Vermillion, N.D.). To read more about the violin, visit

HPC regrets that John's work was not noted and credited in the
original report.
