PHILADELPHIA (CBS) — Three Philadelphia city employees have been honored for outstanding service. They are the winners of this year’s Richardson Dilworth Awards.

Mayor Michael Nutter started the awards in the name of one of his most respected predecessors, four years ago, and this year added two new categories to recognize outstanding city workers. Police Detective Joseph Murray, known to the department’s thousands of social media followers for his pithy posts, won for Innovation in Government. Librarian Anne Hornbach, who oversees the Torresdale branch of the Free Library, won for excellent customer service.

The top prize of Distinguished Public Service went to Parks stewardship director Barbara McCabe.

“I get to work with some of the best, most passionate citizens in our city, the park volunteers,” McCabe says. “These volunteers give up their time and their sweat and their talents to make their neighborhoods better. They’re pretty special people, so I feel privileged to work with them and to help them if I can.”

The award, sponsored by Dilworth-Paxson and Blue Cross, carries a $5,000 prize.
