Gideon was a man who was caught for a crime and sent to court, but he couldn't afford a lawyer so he claimed that the sixth amendment entitled him to one. The court didn't agree with him since this hadn't happened before where a court would provide a lawyer. So they denied his request and sent him to jail for five years. While in prison he visited the library there often and gained knowledge there of the constitution. Then he wrote a petition to the supreme court, and they listened to him. They overturned his conviction and the vote was unanimous.
