A businessman known to his fans as Chicago's "nut king" died earlier this week at the age of 90, The Chicago Sun-Times reported.

Herbert 'Herb' Kenney founded Nuts on Clark, a business selling gourmet popcorn, as well as several varieties of nuts, more than 30 years ago, according to the Sun-Times.

The business, which sells hundreds of items — including cheese popcorn, caramel corn, dried fruits, and candies — operates multiple stores throughout Chicago.
