During the Gilded Age, the opera was the place to see and be seen, with patrons often more concerned about social climbing than the music. To complement their formal attire, attendees completed their outfit with a pair of opera glasses. “The wealthier a person was, the more diamond-encrusted [their opera glasses] were,” Lawrance explains. “They were made with gold and other rare materials, just like any other piece of jewelry.”

Any Gilded Age family of means had silverware on their table, Lawrance says, with the wealthiest households opting for sterling silver from Tiffany & Co., Black, Starr & Frost, or similar manufacturers. Given the high cost of sterling silver, it was common for mansions of the era to contain walk-in safes to house silverware and other valuables. “The safes were mostly used to house the family silver used for entertaining, as well as papers that needed to be protected from fire or other damage,” says Linda Rocke, a spokesperson for the Ventfort Hall Mansion and Gilded Age Museum in Lenox, Mass.

But having a substantial silver collection was about more than impressing guests with needlessly large place settings. “Many of these objects weren’t just symbols of wealth themselves,” says Lawrance, who regularly shares images of the era on Instagram. “They were also about having the money and the servants necessary to maintain them.” In this case, it meant having the staff required to keep the silver polished and tarnish-free.

With botany all the rage among American and British upper classes, estates on both sides of the Atlantic often featured lavish gardens, as well as greenhouses and conservatories designed to showcase the family’s collection of exotic plants. But that wasn’t enough: the Gilded Age elite also wanted to incorporate greenery into their interior decor.

This was easier said than done, though, as the heavy drapery fashionable at the time made these homes quite dark on the inside. Ultimately, this led to the popularity of one houseplant in particular: the parlor palm. “Parlor palms can survive without much light or much care,” Lawrance explains. “You’d see them all over the house: on plant stands with marble tops, on the mantle, on landings.”

Though we take it for granted today, during the Gilded Age, electricity was a source of both excitement and fear. While some people, including financier J.P. Morgan, saw limitless potential in the emerging energy source, other well-to-do New Yorkers were skeptical about whether it could be safely tamed.

Beginning in 1881, early adopters like Morgan wasted no time electrifying their residences and offices using private steam-powered generators, and according to Lawrance, those who had electricity wanted to flaunt it. “Sometimes in pictures [of Gilded Age home interiors] it looks like they haven’t yet put lampshades on light fixtures, but that was intentional,” he says. “Light bulbs were expensive objects, and if you had them, you wanted to show them off to impress people.”

Often described as the “Swiss army knife” for women of the Victorian era, châtelaines were popular accessories for women across different socioeconomic classes. “Châtelaines were decorative belts with hooks or clasps worn at the waist, with a series of chains suspended from it,” says Locke. “Each chain holds a useful household item, such as keys and scissors.” While maids and seamstresses wore châtelaines that were strictly utilitarian, the ladies of the house who employed them wore ones made of silver and gold that they purchased from a jeweler as a fashion accessory.

Whether they were residing in their spacious city mansions, or their sprawling summer homes,  upper-class Gilded Age families relied on their household staff for everything from getting dressed, to getting a refreshing drink in the conservatory. To ensure these needs were met immediately, many homes had a call system for their staff.

“There were typically tapestry pulls next to fireplaces,” Lawrance explains. “They were attached to a string at the top, so when you pulled it, it pulled a wire that would set off a button in a call box in the basement. This let the servants know that the lady of the house wanted tea in the drawing room, or in the yellow drawing room versus the blue drawing room.”

The unprecedented technological advancement of this period was perhaps most visible in the field of transportation. “In the beginning of the Gilded Age, [horse-drawn] carriages were the main mode of transportation,” Lawrance explains. “The carriage of a millionaire would certainly have been gleaming and highly polished, and would have probably had a family crest on it.”

Many families also owned private, ornately decorated rail cars for train travel; most notably, those with ties to the railroad industry, like the Vanderbilts and Goulds, he notes. The end of the Gilded Age saw the introduction of the first horseless carriages, with the first gas-powered automobile patented in 1886, and Henry Ford unveiling his first motor vehicle, the Quadricycle, in 1896. With or without a motor, carriages of this era were another way for families to showcase their wealth and status.

Although professional photography had been around for decades, and the Kodak handheld camera was patented in 1888, sitting for painted portraits remained popular among the Gilded Age elite. “There were family portraits, portraits of the lady or man of the house—sometimes numerous portraits done of them for different rooms, different houses, at different times of their life, painted by different artists,” Lawrance explains. “Having portraits painted was a sign of wealth: especially those done by famous artists, like John Singer Sargent and Philip de László.”

By the end of the 19th century, there were 136 public water supplies in the United States, along with an expanding network of sewer systems in various cities, but at first, only the rich could afford to take advantage of these developments in sanitation. “In the Gilded Age, having indoor plumbing and a bathroom inside your home would have been very expensive,” Lawrance notes.

Those who opted to convert a room into a bathroom, or add one onto their home, installed, at minimum, a sink, toilet, and bathtub (unless it was a ground-floor powder room, in which case, there wouldn’t have been a tub). Others took it a step further, adding fixtures like a bidet, sitz bath, foot bath, or dental sink.

But those who wanted to create their own personal health resort at home invested in a standalone ribcage shower. Also known as a “needle bath,” medical experts of the time touted the many supposed health benefits of these showers, claiming that the multiple streams of water sprayed on the body could treat liver complaints, insomnia, constipation, poor circulation, fatigue, and “the enervating effects of city life.” People in good health stood to gain from ribcage showers, too, as this type of hydropathy was said to be both energizing and relaxing.

At a time before television and radio, the evening entertainment in a household typically involved someone playing a musical instrument. “Pretty much every family with a daughter had a piano,” Lawrance said. “At the time, it was the job of young girls to learn how to be a good mother and housewife, and how to entertain, so many played the piano.”

Never ones to miss an opportunity to flash their cash, the Gilded Age elite owned top-of-the-line grand pianos from manufacturers like Steinway & Sons, Mason & Hamlin, and Baldwin, some of which were gilded, or had some other ostentatious adornment. “A lot of the pianos from that time had paintings of French scenes, like cherubs, or aristocrats in gardens,” he says.

As impressive as those pianos were, the ultimate musical instrument status symbol was the pipe organ. “They were very large, and very expensive,” Lawrance explains. “These organs often had to be designed when a house was being built.” Even if a member of the family knew how to play the organ, professional organists were typically hired to play for the household, he notes, while player organs grew in popularity after the turn of the century.

The first World’s Fair to take place in the United States was held in Philadelphia in 1876, and also celebrated the 100th anniversary of the country’s founding. Officially known as the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, inventors from the 37 countries participating in the fair showed off their latest innovations, including a Scottish-born professor of vocal physiology at Boston University named Alexander Graham Bell.

After years of attempts, Bell achieved his goal of transmitting sound over a wire, and on March 7, 1876, obtained his first U.S. Patent for a device he labeled as “Improvement on Telegraphy”—now better known as the telephone. Though he had tested the technology with colleagues in Boston, Bell’s first public demonstration of his telephone took place a few months later, on June 25, 1876 at the Philadelphia World’s Fair.
