Brass Cubist Floor Lamp by Robert Sonneman for Koch & Lowy, ca. 1970

Though Robert Sonneman was quite literally born into the lighting business, it took working for another celebrated lighting maker for him to land upon the kind of boundary-pushing modernism for which the New York–based designer is known today.

At the age of 19, fresh off a stint in the U.S. Navy, Sonneman responded to an ad for a position working in the studio of George Kovacs on Manhattan’s Upper East Side, where he became the sole employee. “Although my parents were in the lighting business, they came from a traditional perspective, and Kovacs introduced me to modernism,” Sonneman once said. “It was 1961, and I was immediately captured by the movement.”

While working for Kovacs, Sonneman became captivated by the work of the Bauhaus, and he began experimenting with the influential art and design school’s ideas of functional simplicity in lighting. In 1967, he opened his own studio.

Though Sonneman Design Group produced furniture for a brief time, the designer eventually elected to focus on the one category that had always fascinated him; the brand became known for its floor lamps, sconces, pendants and chandeliers that feature unconventional treatments toward shape and balance, often inspired by modern architecture. Sonneman once said of his work: “I saw the lamps that I built as lighting machines that glorified the industrial aesthetic.”

Indeed, in the spirit of Bauhaus functionality — Sonneman has also cited Mies van der Rohe as being an inspiration — the designer’s work takes function-centric forms and motifs and elevates them while prioritizing technology. This spirit of forward thinking continues today, as Sonneman’s brand, renamed SONNEMAN – A Way of Light in 2003, works with LED bulbs to continue to push the boundaries of what functional lighting can achieve aesthetically.

Current-day releases by SONNEMAN – A Way of Light (still overseen by Sonneman himself) feature 95 percent LED lights and include interior and exterior lighting as well as modular suspended lights as an alternative to track lighting. Sonneman’s vintage pieces, however, are still widely collected on the secondary market.

Collectors know Koch & Lowy for its eye-catching sold brass five-arm chandeliers, sleek chrome swing-arm floor lamps and clever table lamps with marble bases. With a wide range of sculptural mid-century modern and 1970s-era fixtures created by the likes of George Nelson, Karl Springer, Piotr Sierakowski and others, the American lighting manufacturer elevated the design of furniture and home decor from the postwar era onward.

Ernest Lowy founded Koch & Lowy in New York in 1946, initially running the firm with his son, Thomas. Over the years, collaborations with notable designers such as American artist Neal Small — known as the “Prince of Plastic” for his innovative use of Plexiglas and Lucite — yielded iconic pieces such as Koch & Lowy’s biomorphic, clear-glass pendant lights and wall sconces for German manufacturer Peill and Putzler as well as the rare Half Nelson table lamp. 

Created by George Nelson — an architect, journalist and designer who brought a slew of legendary designers to Herman Miller while he was director of design at the company — the Half Nelson table lamp, with its striking form and shade of spun aluminum, was originally designed in 1950 as part of an architectural project of Nelson’s on Long Island. Koch & Lowy put it into production in the late 1970s. 

Throughout the 1960s and 1970s, Koch & Lowy floor lamps gained wide acclaim. Neal Small’s architectural aluminum periscope Skyscraper floor lamp and their Pharmacy tent floor lamp, which Thomas Lowy admitted he copied unwittingly from Omaha architect Cedric Hartman, were particularly popular.

“I’d bought a tent [lamp] in Italy, but it had been made so badly that I decided to make a better one,” Lowy explained to the New York Times in 1976. “I didn’t know that the Italian one wasn’t original. I didn’t know it was a copy of Hartman’s design.”

Nevertheless, Koch & Lowy enjoyed success designing and producing innovative lighting fixtures and other furniture such as the brutalist Mirage coffee table, created by Polish designer and head of Koch & Lowy’s design department, Piotr Sierakowski.

While Thomas Lowy sold the company in the 1990s, the brand’s impact on modernist lighting design endures.
