History

1938
A young electrical engineer, Herbert S. Foth, organized a small engineering company in Green Bay, Wisconsin. That first year, Foth had four members on the payroll, and our clients included several municipalities in northeast Wisconsin.

1939 – Early 1940s
Foth and Patrick Boyd joined forces as Foth and Boyd. The company also began a long-term engineering relationship with Austin Straubel Field, now Austin Straubel International Airport.

Mid-1940s
We employed approximately 24 members. Patrick Boyd left the partnership and the business continued as Foth & Porath, Inc. Many municipal clients who were added during this time continue to work with Foth to this day.

1950
Jack Horner, World War I pilot and former Federal Aviation Administration official, joined our company to form Foth, Porath & Horner. The firm specialized in airport engineering and served clients throughout the upper Midwest.

1952
A major fire destroyed Foth, Porath & Horner’s Green Bay offices. Our members moved quickly to reestablish operations.

Foth & Porath changes its name to Foth & Van Dyke and Associates, Inc.

1970s
Our business focus expanded significantly to address the era’s growing environmental awareness. New services included wastewater treatment, water supply, and environmental studies. These services, combined with the firm’s traditional civil engineering capabilities, were the precursor to today’s Foth Infrastructure & Environment, LLC.

We ranked in top 500 by Engineering News Record (ENR). A food plant division was added to serve the process engineering needs of dairy and other food processing clients. Paper industry expertise also expanded. These combined resources became the Industrial Division of Foth & Van Dyke, now Foth Production Solutions, LLC.

We expanded geographically throughout Illinois, Iowa, and Minnesota.
