After funding the research that helped Jane Jacobs produce her landmark book “The Death and Life of Great American Cities” nearly 50 yeas ago, the Rockefeller Foundation has inaugurated the first Jane Jacobs Medals.

Barry Benepe, the 79-year-old founder of Greenmarket, will receive the first medal for “lifetime leadership.” Omar Freilla, the 33-year-old founder of Green Worker Cooperatives in the Bronx, was named the winner of the first medal for “new ideas and activism.”

The medals will be presented in September in conjunction with the opening by the Municipal Art Society of an exhibit titled “Jane Jacobs and the Future of New York.”
