Which man is not related to the development of the modern assembly line?

Henry Ford is often credited with popularizing the modern assembly line, but he did not invent the concept. The assembly line's development can be attributed to earlier innovations by figures like Eli Whitney, who introduced interchangeable parts, and Ransom Olds, who implemented assembly line techniques in the early 1900s. Therefore, anyone not involved in these advancements, such as Thomas Edison or Alexander Graham Bell, would not be related to the development of the modern assembly line.
