Clifford Roberts, 57, a master craftsman who created beautiful violins, violas, and cellos, died Monday, Sept. 6, at his home in Bella Vista from a rare neuromuscular disorder.
Mr. Roberts' instruments are owned by members of the Juilliard and Mendelssohn String Quartets, the Philadelphia Orchestra, and several other ensembles.
Soon after he joined the Philadelphia Orchestra in 1990, John Koen bought a cello from Mr. Roberts. When Koen played it for a former teacher of his at the Curtis Institute of Music, David Soyer, "he approved because it was loud, and David liked loud," Koen said.
Like all of Roberts' instruments, the cello has a distinctive orange hue. "There is this mystique about Stradivarius' secret formula for varnish," Koen said. "Cliff had his own magic formula and would tell people who owned his instruments that after 200 years or so the orange would fade to 'Stradivarius red.' "
