Rose Friedman, Economist and Collaborator, Dies at 98

Rose Friedman, a free-market economist whose extraordinary collaboration with her husband, Milton, proved essential to his Nobel-prize-winning career, died Tuesday at her home in Davis, Calif. Her birth records have been lost, but her family said she was probably 98.

The cause was heart failure, according to a statement approved by the family and issued by the Friedman Foundation for Educational Choice, founded by Milton and Rose Friedman in 1996 to promote school vouchers and other school-choice policies.
