Robert Tucker was appointed as the new fire commissioner of the FDNY and was sworn in on Aug. 12. He is the 35th person to hold the position. City officials said, previously, Tucker worked for the Queens DA’s office and was CEO of a private security and cyber intelligence company, T&M Protection Resources. They said he also worked at the FDNY, though never as a firefighter, served as secretary of the FDNY Foundation, and was also a past honorary fire commissioner. “I can think of no higher calling than serving as the fire commissioner for the City of New York,” he said.
