George Henry Baumann founds Great Lakes Rubber and Supply (GLR) under the belief that products like o-rings, hose, belting, gaskets and the newly invented PTFE (DuPont Teflon) would increase in demand during the post-World War II boom. He starts the business in November with one other employee in a 500-square-feet location at 735 N. Jackson St. in downtown Milwaukee.

Under George’s leadership, the company relocates to 3118 N. Teutonia Ave. in Milwaukee, doubling the size of its facility. Around the same time, GLR partners with Parker Hannifin to become an authorized distributor of its o-rings, seals, hose and fittings product lines. This relationship with both Parker’s EMG and FCG divisions would continue to grow for the next 60+ years.
To meet a growing customer base and product line, GLR relocates to its current Milwaukee headquarters at 6150 N. Flint Rd., expanding its facility to 25,000-square-feet. The expansion allows GLR to invest in gasket manufacturing and hydraulic assembly equipment.
To meet the growing needs of OEM customers, Great Lakes Rubber opens a warehouse facility in Loves Park, IL. The location sees rapid growth and quickly becomes a well-known brand in the Rockford area.
Thomas Baumann, George’s son, becomes President and expands GLR’s Illinois presence by acquiring CC Sales, a mother-daughter distributor serving the Rockford area.
George Baumann, the founder’s grandson, becomes President after having served in varying operational and managerial roles at GLR since 2011.
GLR completes a new logo and a complete renovation of the office at 6150 N. Flint Rd. The fresh look speaks to the investments in growth GLR plans for the upcoming decades.
