In Aetna Life Insurance Co. v. Moses, 287 U.S. 530 (1933), the widow of an employee who was killed in the course of his employment, and who was also his administratrix and the sole beneficiary under both the Compensation and the Wrongful Death Acts, elected to receive compensation. It was conceded that the widow, before her election, was alone entitled to the benefit of the Wrongful Death Act, and the question was who, in consequence of her election, was the proper plaintiff to bring the action. The Supreme Court held, construing 33 (a) and (b), that the Compensation Act, called into action by her election, operated to transfer to the employer all her right of recovery under the Wrongful Death Act.
