What man was not related to the development of the modern assembly line?

Henry Ford is often credited with the development of the modern assembly line due to his innovations in manufacturing techniques for the Model T. However, Eli Whitney, known for his work with interchangeable parts and the cotton gin, was not directly involved in the development of the assembly line as it is understood today. His contributions laid the groundwork for mass production, but the assembly line concept was primarily realized through Ford's implementation in the early 20th century.
