48 Gramercy Park North

Edward Ringwood Hewitt came from a family accustomed to making things happen. His grandfather was the industrialist and philanthropist Peter Cooper; his father, Abram Stevens Hewitt, became mayor of New York. Edward’s childhood home was nearby at 9 Lexington Avenue—a different house, and an important distinction in a neighborhood where family stories easily migrate from one address to another.

The Smithsonian’s history of the Hewitts describes a household in which drawing, languages, music, and practical accomplishment mattered. Edward carried that appetite for learning into an exceptionally varied adult life. He married Mary Ashley in 1892, and the couple had four children. By 1920, contemporary newspaper reporting places Edward and Mary at 127 East 21st Street.

Lucy’s larger world

The newspaper notice that fixes the family at this address was ostensibly about their daughter Lucy’s engagement. Its more revealing news concerned her work. Rather than making a formal society debut, she had served with the American Committee for Devastated France, working in New York and overseas. For six months she directed reconstruction work at Vic-sur-Aisne.

That short account opens a window beyond the Park’s gates. The house belonged to a family whose name appeared in society columns, but Lucy’s experience was also one of damaged French communities and the practical demands of recovery. The address connected Gramercy’s domestic life to the consequences of a war fought an ocean away.

When Geoffrey T. Hellman visited in 1934, he found workshops and laboratories on the top floor, crowded with bottles and instruments. Hewitt worked there with his son Ashley. Hellman called him “the last mechanic in the gentleman class.” The phrase caught a man for whom comfortable circumstances were an invitation to work with his hands.

Hewitt’s technical career ranged well beyond this house. In England he worked with Hiram Maxim on an experimental steam-powered aircraft. He developed automobiles and truck engines, founded the Hewitt Motor Company, and later worked as a consultant to Mack. The Park-facing address was one part of a life spent following problems wherever they led.

A letter about an eclipse

One unusually vivid trace survives in the scientific record. In 1937, Nature acknowledged a communication from Hewitt at 127 East 21st Street about a color photograph of the total solar eclipse of January 24, 1925. He had used Autochrome plates that he sensitized himself; the result had appeared in Scientific American that April.

The journal was correcting a claim that a later eclipse photograph had been the first in color. Hewitt’s earlier image had limitations, including little visible structure in the corona, but it demonstrated what his treated plates could register. The correspondence does not establish where he took the photograph. It does establish that this quiet Gramercy address belonged on the return envelope of a scientific argument.

From Gramercy to the Neversink

Trout demanded the same close observation as machinery. In 1918 Hewitt established the Big Bend Club on 2,700 acres in the Catskills, where the Neversink River became a testing ground for his fishing ideas. He experimented with flies that provoked a fish’s response through size and movement, rather than merely copying the appearance of an insect.

He also applied engineering to the angler’s equipment: reels, wading footwear, and rods. His work extended to stream improvement, hatcheries, and trout nutrition. Books carried those experiments to other fishermen, among them Secrets of the Salmon, Telling on the Trout, and Hewitt’s Handbook of Fly Fishing.

Read alongside the workshop and eclipse stories, the fishing becomes part of a coherent temperament. Hewitt liked a question that could be tested: change the material, adjust the mechanism, watch what happens. He died in 1957. The house’s next conspicuous experiment would be architectural.

Walk past No. 48 and the verandas stop you. Slender dark posts and curved braces frame two open levels across the front. Instead of a flat wall between the rooms and the Park, there is an intermediate place: outdoors, elevated, and still unmistakably part of the house.

The addition is commonly dated to 1968 in published building histories, although that date has not been independently confirmed in an alteration permit. What is clear from the façade is the effect. The ironwork gives the lower part of the house a lightness very different from the weight of the masonry above it. Strong horizontal lines spread across a remarkably narrow frontage.

These are useful spaces as well as a memorable street image. A veranda changes the experience of a window: the view becomes somewhere one can sit. The Park supplies depth, foliage, and moving light; the open framework makes those things feel close to the rooms behind it.

The house’s distinction lies in that combination. Its proportions recall the older residential square, while the verandas express a later desire for outdoor living. Neither part needs to be mistaken for the other. Together they make No. 48 immediately recognizable.

By 1979, a cooperative corporation owned the building. That date is established by a New York appellate court decision issued in 1987, which described a five-story building then containing nine apartments. An address once closely associated with one family had become a collection of households sharing the responsibilities of an old house.

The change was more than administrative. Separate apartments had to make their own lives within the townhouse’s inherited height, width, and openings. A park-facing apartment photographed for a 2018 listing shows one response: a lofty room with a mezzanine, tall windows, and a veranda beyond. Its furnishings belong to that later moment, not to the Hewitts.

The photographs make the building’s appeal legible from the inside. The room’s height gives it generosity; the glass draws the eye toward the trees. Outside, the verandas are an architectural signature. Inside, they are a daily pleasure, extending a compact Manhattan home toward the open square.
