Ring Before Knock: When Were Doorbells Invented?

The Evolution of Door Signals: From Knocking to Doorbells

For centuries, people have been using various methods to announce their presence at a door. From knocking on wooden doors to ringing massive metal bells, people had to resort to a loud and sometimes uncomfortable process to draw attention. The evolution of the technology, however, has simplified this process, and the doorbell is one of those inventions that make our lives more comfortable. Let us go back in time to find out when doorbells were first invented and how they have evolved over the years.

Early Forms of Door Signals

Before doorbells were invented, people used other methods to announce their presence at a door. These methods included knocking and bell-pulls. The term "door knocker" derives from this age-old custom. For quite some time, people would either knock with their knuckles or use some kind of instrument to produce noise and alert the people inside of their arrival. The method was inefficient and uncomfortable, particularly for those who suffered from arthritis or had a weak grip.

The bell-pull was another solution that people used to announce their presence at a door. The bell-pull was essentially a rope attached to a doorbell, and people would tug on it to ring a bell located inside the house. Bell-pulls were most commonly found in wealthier households, though they didn't solve the problem of announcing oneself to the occupants of the house. After all, the person ringing the bell still had to stand outside the entrance, waiting for someone to open the door.

The Electric Doorbell

The first electric doorbell was invented by Joseph Henry in 1831. However, due to the lack of reliable electrical systems, it was not widely used until the mid-1800s. The first electric doorbells were simple buzzer systems that required hard-wiring and manual operation. These early doorbells had a button on the outside of the door that visitors would push, and a bell or buzzer inside the home would ring. It was the start of a new era of doorbell technology which revolutionized the way visitors could notify the occupant of their presence.

In 1858, another breakthrough occured when Frederick Bakewell invented a doorbell that could be operated using a battery. Unlike the original doorbells, this was a wireless doorbell and added to the convenience factor - it could be moved around or taken to the garden to call for help if required. In 1881, the first electric doorbell with automatic reconnection was patented by Samuel O'Reilly, an Irish-American inventor. This invention allowed the doorbell to continue ringing until the door was answered, regardless of how long the visitor pressed the button.

Mechanical Doorbells

In the late 19th and early 20th century, mechanical doorbells became popular, with designs that ranged from simple chimes to more complex bells and buzzers. Mechanical doorbells were available in an extensive range of styles, from brass, bronze, and iron plates to ornate and intricate designs that match the architecture of the home. Unlike electric doorbells of the time, mechanical doorbells didn't rely on electricity, making them an ideal alternative when electricity was either not available or unreliable.

The mechanical doorbells worked by a simple mechanism triggered by a pull or twist of a handle, pulling a clapper against a bell. As the clapper hit the bell, the sound produced would be similar to the sound produced by a wind chime. Apart from the sound, Mechanical doorbells have a decorative value and are sought after even today, especially by collectors and antique enthusiasts.


Door signals have come a long way since the days of knocking. The electric doorbell revolutionized the concept of doorbells, making it more convenient and accessible. However, mechanical doorbells still provide an aesthetically pleasing option in buildings with an old or historic charm. While a novelty and vintage appeal will always be fashionable, the convenience of pressing a button to announce visitors will remain the more favored choice.

Evolution of Doorbell Technology

Doorbell technology has come a long way since the first mechanical doorbells were invented. Today, doorbells not only serve as a signal to visitors but also add to the security of the house. In this article, we will explore the evolution of doorbell technology from its inception to the present day.

Early Doorbells

The first doorbells were mechanical devices that used a system of wires and bells to produce a sound when the button was pressed. These doorbells were commonly used in houses in the first half of the 19th century and were manually operated. The visitor had to pull a rope that was connected to a bell, which produced a sound inside the house. These were also known as "pull bells".

Another type of mechanical doorbell was the twist doorbell, which was invented in the later half of the 19th century. The visitor had to twist a knob to create a sound inside the house. These doorbells were relatively easier to operate than the pull bells.

Electric Doorbells

Electric doorbells were invented in the 19th century and was a significant step ahead from mechanical doorbells. Alexander Graham Bell is credited with the invention of the electric doorbell. Electric doorbells worked by using an electromagnet to produce a sound. When the button was pressed, it created a current that passed through the electromagnet, which produced a sound.

Electric doorbells became popular quickly due to their reliability and ease of installation. They were considered a more elegant solution than mechanical doorbells, as they did not require any physical strength to operate.

Wireless Doorbells

In the mid-20th century, wireless doorbells were invented, eliminating the need for complicated wiring installations. Wireless doorbells work by using radio waves to transmit the signal from the button to the receiver. The receiver then produces a sound to alert the resident of the arrival of the visitor. These doorbells became popular as they were portable and easy to install. They were also less expensive than wired doorbells.

Silent Doorbells

In the 1970s, silent doorbells were developed, which replaced the traditional chime with a flashing light or vibrating alert. Silent doorbells were especially useful for people who have hearing disabilities. They were also helpful in situations where noise was considered disruptive, like a sleeping baby or during important phone calls. Silent doorbells were mostly used in hospitals and nursing homes.

Smart Doorbells

Recently, smart doorbells have become popular, allowing homeowners to answer their door and monitor visitors from their smartphone or tablet. Smart doorbells work using Wi-Fi and a smartphone app. When a visitor presses the button, the signal is sent to the smartphone, and the homeowner can answer the door remotely. Smart doorbells have features like motion detection, night vision, and two-way audio communication, making them even more useful for enhancing security and convenience.

In conclusion, doorbells have come a long way from the mechanical pull bells of the 19th century to the smart doorbells of the 21st century. With the advent of new technology, doorbells have become more reliable, more convenient, and more secure.

Impact of Doorbells on Society

The history of doorbells dates back to the 1830s when people began experimenting with various electronic door signals. As the technology advanced, doorbells gradually became a common feature in households. From being a luxurious item, doorbells eventually became an integral part of homes around the world. In this article, we will discuss how doorbells have impacted society in various ways.

Increased Security

One of the primary benefits of having doorbells is increased security. Earlier, people relied on knockers or bells to announce their arrival which could be missed by those inside. With doorbells, homeowners became more aware of who was at their doorstep. Moreover, doorbells also helped avoid any unwanted guests from entering the house, enhancing privacy and safety.

Today, doorbells come equipped with various features such as cameras, motion sensors, and intercoms, making them even more secure. These advanced doorbells notify homeowners of any unusual activity and allow them to deter intruders. The security features of modern-day doorbells have significantly contributed to reducing the crime rate across the world.


Door signals such as doorbells have made communication more convenient. Earlier, visitors had to physically enter the house to get the attention of the people inside. However, with doorbells, one can simply ring the bell and wait for the homeowner to answer. Moreover, homeowners can monitor their doorsteps better with the help of doorbells, especially when they are busy with daily chores.

With the advent of technology, doorbells have upgraded significantly from their traditional form. The modern-day doorbells come with advanced features such as smart lock integration with remote access, voice-activated notifications, and instant video feed activated doorbells, making it even more convenient for homeowners.

Cultural Significance

Door signals including doorbells have become a cultural symbol of hospitality and welcome. In many cultures, doorbells are used to initiate communication or show gratitude towards guests. The classic example of this is when a guest rings the doorbell and the homeowner greets them with a smile, inviting them inside their warm and welcoming house.

Doorbells have also become an integral part of literature and media. For example, the famous dialogue in the book "The Great Gatsby" by F. Scott Fitzgerald, where the doorbell rings, and the protagonist Nick Carraway is reluctant to answer the door, is one of the most memorable scenes in literature. Similarly, in movies and TV shows, doorbells are used to create suspense, just as they are in real life.

In conclusion, doorbells have come a long way since their invention and continue to play a vital role in our daily lives. They have not only enhanced our security and privacy but also made communication more convenient and have become a symbol of hospitality. With the advancement of technology, doorbells are continuously evolving, and who knows, we might have flying doorbells soon!
