GLC History


The company originated as the Hurlbut Calcium and Chemical Company in 1871 by entrepreneur, Fred Hurlbut Sr., who realized the strategic location of Green Bay and the economic opportunity of Great Lakes shipping following the Civil War.


By this year, a second generation owner, Fred Hurlbut Jr. had grown the company into a major coal and bulk distributor in Northeast Wisconsin.


The F. Hurlbut Company relocated to its current location at the mouth of the Fox River. At this time the Hurlbut Calcium and Chemical Company began and started to provide agricultural limestone to farmers in the area.


Frederick L. Garner joins the company and after serving in various capacities in the Hurlbut Company, he purchased Hurlbut Calcium and Chemical from the family some twenty years later.


During their centennial anniversary, under the direction of Wesley H. Garner I, Charles Bennett, and Frederick J. Lenfestey, third generation family members, the Hurlbut Company diversified the calcium and concrete products businesses.


The company changes its name to Great Lakes Calcium Corporation to better reflect its strength. It continues to invest corporate profit in the plant and equipment to produce a diverse and high quality product line.


Wesley Hurlbut Garner II, the fifth generation family member purchases Great Lakes Calcium Corporation. The company, also known as GLC, continues to grow and reinvest in the modernization of drying equipment, updating process control systems and adding additional storage capacity.


As a better reflection of the current products and markets, the company changed its name from Great Lakes Calcium to GLC Minerals, LLC. In addition to the name change, GLC launched GLC Integrated Services, LLC, a trans-load company serving Wiconsin’s dairy industry with cost-effective movement of product from rail to truck to farm, and Hurlbut Holdings, which will serve as the parent holding company for GLC Minerals and GLC Integrated Services.


Under the leadership of Wesley Hurlbut Garner II, GLC Minerals celebrates 150 years in business.
