Skyscraper Day commemorates the birthday of Louis H. Sullivan on September 3, 1856.
A mentor to Frank Lloyd Wright, Sullivan is considered the father of the American skyscraper. His most famous buildings include the Guaranty Building in Buffalo, New York; Wainwright Building in St. Louis, Missouri; Schiller Building and Theater in Chicago, Illinois; and the Auditorium Building in Chicago, Illinois.
To be considered a skyscraper today, a building must have a minimum height of 150 meters (about 492 feet) and a minimum of ten floors per the Council on Tall Buildings and Urban Habitat (CTBUH).
The first structure to be referred to as a skyscraper was the Home Insurance Building in Chicago, completed in 1885. This 10-story building, standing approximately 138 feet tall, is often credited as the first to use a skeleton frame with a steel infrastructure, allowing for greater height and stability. In a skeleton frame, the walls do not bear the weight of the building; the frame does. This was a huge advancement in structural engineering at the time.
Currently, the world's tallest building is the Burj Khalifa in Dubai, United Arab Emirates. It was completed in 2010 and stands at a staggering height of 828 meters (2,717 feet) with more than 160 stories. If the Jeddah Tower in Saudi Arabia is finished at 1,000 meters (3,281 feet), it will surpass the Burj Khalifa. As of July 2023, it is 1/3 completed.
