Besides being known as the center of the automotive industry in the U.S., the Motor City has plenty of historic firsts that don't have to do with cars. In fact, these seven things invented in Detroit are extremely important and revolutionary! Read on as we share them with you. See how many you knew about or which ones are completely new information!

1. The first mile of concrete was made in Detroit.

Detroit is known as America's automotive industry, so it makes sense that the first mile of concrete was made in the city. The first construction of concrete began on Woodward Avenue in Detroit. And now, like many cities across the country, you see a lot of what people call "the country jungle."

2. The first assembly line for vehicles was created here.

The first automotive assembly line was developed in 1913 when Henry Ford thought it was a good idea to put together car parts with labor and movement for faster production. The rest, as they say, is history.

3. The first three-lens traffic light in Detroit.

William Potts is responsible for creating the first modern, three -ens traffic light in the downtown area. The first light was installed on the corner of Woodward and Michigan Avenues and are ubiquitous all over the world.

4. The first radio news program was broadcasted in Detroit.

In the 1920s the first news program was broadcasted on the radio. At first, the broadcast (which was on Station 8MK), would only play music, until the radio staff collectively worked out a way to broadcast the news. We guess that counts as one of the things “invented” in Detroit?

5. The first individual phone numbers were born.

In 1879, Detroit welcomed the first individual phone numbers to households, so you did not need to ring an operator first to connect to friends and family or connect to a party line.

6. The first Van Gogh to enter a museum.

The Detroit Institute of Arts holds the first Van Gogh painting to ever be shown and entered in a U.S. museum. Van Gogh's Self Portrait is one of the DIA's most important and respected pieces.

7. The first African American legend.

There is no doubt that famous boxer Joe Louis is the first African American to reach hero status. He wasn't born in Detroit, but his family moved to the city and it was here that Joe Louis gained his fame as a boxer, holding the heavyweight championship from 1937 to 1949.
