Richard Grace, of Harrison, owned a construction company and spent 15 hours a day at Ground Zero for four months. That led to lung cancer and his death in 2017.

“I’m very proud and so honored that he is being recognized because he was there for so long and tried so hard to do his best. And he did,” his widow, Barbara Grace, said.
