Ellis S. Rubin (June 20, 1925 – December 12, 2006) was an American attorney who gained national fame for handling a variety of highly publicized cases in a legal career that spanned 53 years. He was famous for his innovative defenses and his propensity for handling lost causes. Rubin won the first case in Florida using the “battered woman” defense. He also worked to free a man, James Joseph Richardson, who had been wrongly imprisoned for 21 years for fatally poisoning his seven children, and created the nymphomania defense in a case involving prostitution.
