My friend Lanny Ebenstein — a biographer of Milton Friedman — sends this remembrance of Rose Friedman by email:

Rose Friedman led a remarkably full and productive life. Like her husband-to-be, Milton, she enrolled in college at 16, in her case, at the University of Chicago in 1928, four years before Milton arrived on the scene. Like him, she became a graduate student in economics at Chicago in 1932. They met as graduate students and began a lifelong partnership and intellectual collaboration. Rose particularly influenced Milton with respect to political ideology. Somewhat more conservative than he, she was also more practical. The highlight of their intellectual collaboration was “Free to Choose,” the 1980 television series and book that brought the Friedmans’ ideas to tens of millions around the world.
