* Henry Ford himself: While not a hands-on engineer in the detail-oriented sense, Ford's vision and insistence on simplification and standardization were paramount. He championed the innovations that made mass production possible.
* Childe Harold Wills: A close associate of Ford's from his early days, Wills was crucial in the engineering and design process. He was deeply involved in the development and refinement of the Model T.
* Joseph Galamb: A significant contributor to the mechanical design and production aspects.
* Others: Numerous engineers, designers, and skilled machinists worked within Ford's growing company. The development was a collaborative effort. The contributions of many individual workers remain largely undocumented.
It's important to remember that the Model T's success wasn't solely due to its design, but also to Ford's revolutionary assembly line and mass-production techniques. Many individuals played a part in both the design and manufacturing processes.
