John Jobbagy and other butchers will vacate a building in the Meatpacking District slated for redevelopment. When John Jobbagy’s grandfather immigrated from Budapest in 1900, he joined a throng of European butchers chopping up and shipping off meat in a loud, smelly corner of Manhattan that New Yorkers called the Meatpacking District.Today only a handful of meatpackers remain, and they’re preparing to say goodbye to a very different neighborhood, known more for its high-end boutiques and expensive restaurants than the industry that gave it its name.Jobbagy and the other tenants in the district’s last meat market have accepted a deal from the city to move out so the building can be redeveloped, the culmination of a decades-long transformation.“The neighborhood I grew up in is just all memories,” said Jobbagy, 68.
