Thurston Greene, the last surviving member of a New York team of attorneys tasked with taking on Depression-era gangsters and racketeering, died of natural causes on July 31. He was 101.

In 1935, just three years after graduating from Harvard Law School, the young attorney was enlisted by then special prosecutor Thomas E. Dewey for the “Gotham Gangbusters,” a team of 19 idealistic young men and one woman responsible for bringing down such legendary mafia figures as Lucky Luciano and tackling Tammany Hall corruption. As the first hired, Mr. Greene managed the office.
