The people

Craft & capital

A fine instrument is a partnership between the maker, the player and the investor. Kleos brings together the craft that builds value and the discipline that structures it.

Robert Brewer Young

Maker of new master instruments

A renowned luthier known for crafting fine violins, cellos and violas inspired by the Cremonese masters. Trained in the artist's studios above Carnegie Hall, Robert has cared for instruments by Stradivari, Guarneri and other Italian greats, and now devotes himself to making signature instruments in their spirit.

His instruments are played by soloists and members of leading orchestras, including the Stockholm, Los Angeles and New York Philharmonics, and held by institutions such as Harvard University and The Metropolitan Museum of Art. As a cello maker he is represented by J & A Beare, where he is also Director and Head of Scientific Research.
