From a New York Times obit by Clay Risen headlined “Edgar S. Cahn, Legal Reformer in Defense of the Poor, Dies at 86”:

Edgar S. Cahn, a legal innovator whose lifelong commitment to bending the law in the service of impoverished communities included establishing the modern system of federally funded legal services, the country’s first public-interest law school and an entirely new currency based on time, died in Bethesda, Md….

Mr. Cahn and his wife, Jean Camper Cahn, arrived in Washington in 1963 with newly minted Yale law degrees and a passion for the sweeping social reforms that were starting to bubble up in the Kennedy administration.
