When designers Robin Standefer and Stephen Alesch describe the light fixtures theyve created since starting their firm Roman and Williams 22 years ago, they speak of them endearingly, as if they were zany aunts, uncles, and cousins. Woodruma wood lamp with a slotted shadeis heavy and grumpy, per Alesch, while Oscara pendant with a gleaming, disclike brass shade is friendly, chubby, and gregarious. Felixa more angular variationis a little edgier.Its a family tree, Standefer says.Robert WrightBeginning this week in New York, Standefer and Alesch are staging a family reunion of sorts through a poetic new installation installed in a stately Queen Annestyle warehouse. The exhibition, titled A Certain Slant of Light, showcases 100 lights that the ELLE DECOR A-List Titans have designed for Roman and Williams Guild (their studios product arm) by suspending themconstellation-likefrom the ceiling of a towering, triple-height room.Lighting has been a category that really captivates us, Standefer explains. It just has a combination of art and science that Steven and I love. After more than two decades designing, experimenting, and obsessing over lights, the pair thought, This is career spanning, and it's time.Lighting has been a category that really captivates us.Not only is A Certain Slant of Light a celebration of Roman and Williamss achievements in lighting design, but its also an homage to the changing of the seasons. The name of the exhibition, in fact, is derived from an Emily Dickinson poem. Standefer remembers the poem from her days at Smith College, where she studied art. I remember not only this poem, but also several poems about light, the mood of the season, and about the life and death of plants, she says.The perfect antidote to winters gloom? A room illuminated by the warm glow of dozens of fixtures. There's something uplifting and strong about having all these lights together, like a night sky in one place, she adds.Robert WrightStarting Tuesday, A Certain Slant of Light will be free and open to the public to experience. As soon as they step into the soaring space at 6 Harrison Street, visitors are welcome to sprawl on Roman and Williams chairs to gaze upward at the various glimmering discs and orbs, or sit quietly and contemplate the fading autumn rays stream through the arched Romanesque windows.The installation includes a dozen newcomers to the Roman and Williams clan. Theres the Axil pendant (a cousin of Oscar) with concentric glass diffusers and a polished brass shade made in a 150-year-old French workshop; the delicate Seed, with its aubergine glass shade and cast-bronze chain; and the hand-carved alabaster Petra pendant. Then theres the prim-and-proper Dahlia table lamp, with a demure alabaster shade that Emily Dickinson herself would have definitely approved of.Everybody, says Standefer, is here.Anna FixsenDeputy Digital EditorAnna Fixsen is the deputy digital editor of ELLE DECOR, where she oversees all facets of ElleDecor.com.
