Nancy Ruggles and her husband Richard were senior faculty at Yale 
when I was there in the 1960s, and continued to be active, 
particularly in the field of national income accounting systems, 
until the 1980s. There is a special issue of the Survey of Current 
Business in the 1980s devoted to the Ruggles' proposals to revise and 
extend the national income accounts and unify them with firm and 
household level data.
