Which architect designed the Seattle Space Needle?

John Graham Jr. designed the Seattle Space Needle. He developed the tower’s architectural design through his firm, John Graham & Company, working with structural engineer John K. Minasian and architect Victor Steinbrueck.

The Space Needle was built for Seattle’s 1962 World’s Fair, whose futuristic theme encouraged bold designs symbolizing the Space Age. Its distinctive flying-saucer-shaped top was inspired partly by a sketch Edward E. Carlson made on a napkin; Graham transformed that idea into a practical observation tower.

Construction began in April 1961, and the tower was completed later that year, ahead of the fair’s opening. It rises about 605 feet and was once the tallest structure west of the Mississippi River. A common mix-up is crediting Carlson alone: he originated the basic concept, while Graham Jr. was the architect responsible for the finished design.
