Who is known for the quote “form follows function”?

The phrase "form follows function" is attributed to Louis Sullivan, an influential American architect often regarded as the father of skyscrapers. This quote encapsulates a fundamental principle of design, emphasizing that the shape or form of a structure should be primarily determined by its intended function or purpose. Sullivan believed that a building's design should reflect its use, thereby advocating for a harmonious relationship between aesthetics and utility.

Sullivan's approach laid the groundwork for modern architecture and influenced subsequent movements, such as the Bauhaus and functionalism, that prioritize the practical aspects of design. His work, particularly in commercial buildings, often showcased this ideology, making him a pivotal figure in architecture.
