Francois Nouvion is well known collector and author of operatic subjects. He was born in Zurich and is a US citizen. He studied at the Swiss Federal Institute of Technology in Zurich and at Stanford University in Palo Alto. He worked mostly in the semiconductor testing equipment fi eld and sold US Equipment from Russia to Tokyo. Early on he became very interested in Opera and developed his knowledge in singing from the reissues by Guy Dumazert. He currently maintains a comprehensive website on tenors (historicaltenors.com) and a YouTube channel on Historical tenors. Although his interest on Irish-French tenor John O'Sullivan dates from his early days, he fi nally started researching the tenor's career in the early 90s after meeting O’Sullivan’s children: Jacques, Colette and Raymonde. After much work contacting the different libraries all over the world, with the Paris and Marseilles libraries being the most diffi cult to work with, he fi nally started writing the O'Sullivan biography in 2007. It is now published. He only regrets that Jacques O’Sullivan, the tenor's son, did not live to witness the publication.
