One hundred years ago (when Bisnow was engraved in papyrus), immigrants came to Chicago to work in the South Side Stockyards. That same square mile between Halsted, Ashland, Pershing, and 47th is still providing jobs, only now in distribution and manufacturing. You know it as the Stockyards Industrial Park, home to 80 companies, and an example of urban revitalization. Back of the Yards Business Council’s Craig Chico and Martha Jungenberg and Matanky Realty’s James Matanky (also commissioner of the area), tell us 70 buildings have gone up since the late ’80s, occupied by companies such as Gourmet Kitchens, Gypsum Supply Co, Tyson, GE Zenith Controls, HydroAire and Testa Produce.
