Richard A. Musgrave (Harvard) died on Monday at the age of 96.  From the Harvard press release:

"Richard Musgrave was one of the great economists and thinkers of the post-war era and beyond, and the Harvard Law School community is grateful for the years that we had the benefit of his wisdom here," said Dean Elena Kagan ’86. "His contributions to the field of public finance are immense, and he will forever be recognized as one of the true pioneers and scholars in that area." …

He taught tax and expenditure policy, economics for lawyers, and taxation and economic development, among other courses. He was appointed the Harold Hitchings Burbank Professor of Political Economy and Professor of Economics in 1970, the chair he occupied until he took emeritus status in 1981. Musgrave was the first person to receive joint appointments to the faculty of Harvard University and Harvard Law School, according to Prof. Emeritus Oliver Oldman, a longtime friend and colleague.

Musgrave is widely viewed as one of the most influential economists of the last century, and a pioneer in the field of public finance. His 1959 book, "The Theory of Public Finance," is considered by experts to be a springboard for important work that came later from economists such as Nobel Laureate Paul Samuelson, who credited Musgrave as a key influence.
