Sam Hill built the roads that connected Eastern Washington to the Coast in the early 1900's. His estate, now an art museum located in Maryhill, WA (named after his daughter). Many thought he was crazy for thinking the roads could be engineered and completed. The use of his name when planning a task or acting in a way that is considered crazy or impossible.
