History of Doors
Doors have been essential parts of buildings for thousands of years.
But where did they come from?
Early humans likely invented doors out of necessity. Back in the Stone Age, placing a rock in front of a cave offered some protection from wild animals or cold winds. Today, doors come in various shapes, sizes, materials, and colors, and door technology is advancing rapidly. Let’s look at the evolution of doors through history and across cultures.
3000 B.C. – The First Door
The idea of a door may have started in ancient Egypt. Tomb paintings from this period feature images of “false doors,” which were more like symbolic windows, representing passageways to the afterlife. Around the same time, in Europe, archaeologists found a wooden door dating back to 3063 B.C. in Switzerland.
2000 B.C.
In Asia, particularly in China and what is now Iraq, stone doors were common. More elaborate doors were made from special woods and decorated with gold in regions like the Middle East, as mentioned in the legend of Solomon. The Romans were using glass in windows, setting the stage for later glass door designs.
1st Century Around 10 A.D.
Heron of Alexandria invented the first automatic door, using heat and pressure to create a dramatic entrance effect. During this time, Romans also created sliding doors, including double and folding doors.
5th -6th Century
In China, the first foot-sensor doors appeared. It was commissioned by Emperor Yang of Sui for library entrances so that patrons could carry books hands-free.
8th Century
Shoji screens were first designed in China but became popular in Japan, where they were made lighter for easy movement. These screens continue to serve as flexible room dividers.
11th Century
The Japanese introduced “fusuma” sliding doors, made of thick paper and wooden frames. They can help transform a room’s appearance by blocking light.
mEDIEVAL eRA (12th -13th Century)
During the Middle Ages, doors became symbols of social status, often decorated with carvings, religious symbols, or metalwork.
Renaissance Era (14th – 17th Century)
Doors became even more ornate with detailed designs and heavy door knockers. A famous example from this era is the “Gates of Paradise,” a bronze masterpiece.
18th Century
In 1888, Theophilus Van Kannel patented the first three-way revolving door, which improved energy efficiency and protection from the weather.
1900s
The 20th century brought major change, including the invention of the sliding glass door. Inspired by Japanese Fusuma, these doors used mass-produced fiberglass from 1932 and were often installed top hung, marking a new era in door design.
1930s
The first electronic automatic doors were introduced to make service easier in restaurants. This led to more modern hands-free and foot-sensor doors, which are now common.
1950s – 1970s
Sensors evolved, first as a mat actuator in the 50s and later as motion sensors in the 70s. This technology spread to sliding doors and alarm systems.
1980s – 1990s
Motion-sensor doors became more popular, especially with infrared sensors that made revolving doors more efficient and safe.
