In the early 1900s there were dozens of automobile manufacturers in the United States, and many more worldwide. Auto manufacturers and parts companies joined trade groups that promoted business. A desire to solve common technical design problems, and develop engineering standards was emerging. Engineers in the automobile business expressed a desire to have "free exchange of ideas" in order to expand their individual technical knowledge base.
