History of Winco

A FAMILY CONCERN SINCE 1931

Johann Otto Kubatzky a German immigrant and an architect by trade, founded The Winco Ventilator Company in 1931 near St. Louis, Missouri. Initially the company manufactured aluminum ventilators in stock sizes made for use in glass block walls for home and commercial use. These were first sold to builders and glazers in St. Louis and surrounding areas.
The first patent for a "window and wall ventilator with a privacy panel" was filed that same year. Otto retired twenty years later when the company was taken over by his two sons, Theodore and Woodrow, whose youngest daughter, Kory, today owns the company with her siblings and their children. Kory Miller is married to Gantt Miller, Winco Chairman, who like Otto, is an architect by trade.
