The Gallery

SL Gallery was established in 2017 by architectural lighting designer and consultant William Schwinghammer. The mission of the gallery is to present works that merge contemporary art, lighting and new media technologies, providing support for the diverse creative practices of emerging, mid-career and established artists within the community. With over 30 years in the architectural lighting industry, Schwinghammer is heavily inspired by visual art, design, and lighting on the edge of concept. He has worked on a number of high-profile commissions including the restoration of The Ritz in Paris, The Woolworth Building in New York, and Herzog & de Meuron’s 56 Leonard Street, as well as Leonardo da Vinci’s Fire and Water Codex world exhibition (in collaboration with Christie’s New York) and the lighting of Vincent van Gogh’s 150-year exhibition Vincent’s Choice in the Van Gogh Museum Amsterdam. The artists selected to showcase at SL Gallery are an extension of Schwinghammer’s vision and have included Fabrizio Corneli, Aleksandra Stratimirovic, Sean Capone and Karen Gunderson.
