The city of Berlin has a long and complex history, with various peoples and cultures contributing to its development over time. The earliest known settlement in the area that is now Berlin was founded by the Slavic tribes in the 7th century. In the late 12th century, a town called Cölln was founded on the banks of the Spree river. In the early 13th century, another town called Berlin was founded nearby.

The official founding of Berlin is usually attributed to the two towns being united in 1307, under the name of "Berlin-Cölln." Over the centuries, Berlin grew in importance as a trade and cultural center, and became the capital of the Kingdom of Prussia in 1701. After the unification of Germany in 1871, Berlin became the capital of the German Empire. Following World War I and the collapse of the German Empire, Berlin became the capital of the Weimar Republic. After World War II, Berlin was divided into East Berlin and West Berlin, with the eastern part being controlled by the Soviet Union and the western part being occupied by the Allies.

**So while there were many people involved in the development of Berlin over time, it cannot be attributed to any single individual**.
