MiTek's History - Two gang nail plates layed out to display boths sides of the product

1955

An engineer named John “Cal” Jureit invented and patented the Gang-Nail connector, the first metal punch-tooth connector plate for wood trusses that did not require supplemental nail fastening.

1956

Cal founded Gang-Nail Systems, Inc., a company that stamped the metal connector plates, invented and sold assembly machinery, and provided engineering services to companies who made prefabricated wood roof trusses for houses.

1960

A St. Louis, Missouri, businessman, Walter Moehlenpah, expanded his hydraulics business, known as Moehlenpah Industries Inc. He entered the residential housing market by patenting his version of a punch-tooth connector plate to make prefabricated trusses. Using Cal Juriet and Gang-Nail Systems as a model, Moehlenpah also manufactured machinery to apply the connectors plates and established operations in Africa, Australia, Canada, and Europe.

1972

Moehlenpah’s company—now known as Hydro-Air Engineering—installed its truss program on a General Electric mainframe computer, allowing manufacturers across the country access to the program via remote terminals, enabling customers to select from dozens of standard designs or enter a special geometry.

1982

During one of the housing’s deep recessions, Hydro-Air Engineering fell on hard times. Paul Cornelson, then Vice President of Ralston Purina, acquired Hydro-Air Engineering from the Moehlenpah family and began implementing changes to make the company profitable once again. During this process, Cornelson learned from customers that the software Hydro-Air Engineering provided to design trusses and generate production documents was the key to their value as a supplier. As Cornelson thought about the software and the role technology would play in its value to its customers, he wanted to create a new identity that would bring technology into the company name. As a result, he forms the parent company, MiTek Industries, Inc., and becomes Chairman & CEO.

1987

MiTek formed a joint venture with British company Bowater, PLC, to acquire Gang-Nail Systems. Gang-Nail Systems and Hydro-Air Engineering continued to operate under the same ownership but as independent brands in the marketplace.

1990

MiTek embarked on a new software project that embraced a then-new Microsoft technology called Microsoft Windows. Using the Windows platform, MiTek developed MiTek 2000 (later renamed MiTek 20/20), the first native Microsoft Windows truss design program with a multi-user, multitasking, graphical user interface.

1991

Hydro-Air Engineering and Gang-Nail Systems operating companies merge under one brand: MiTek Industries, Inc. For the first time, Hydro-Air Engineering and Gang-Nail Systems go to market as one brand, MiTek.

2001

With MiTek on the verge of being sold off by Bowater, PLC, Gene Toombs, then MiTek Chairman, President and CEO, called Warren Buffett of Berkshire Hathaway to discuss the possible acquisition of MiTek. Mr. Buffett wasn’t in the office that day, so his secretary suggested that Toombs write Mr. Buffett a letter. Although skeptical, Toombs and the team at MiTek prepared and mailed a packet of information to Mr. Buffet, including a bubble-wrapped connector plate. On July 31, 2001, MiTek became a member of the Berkshire Hathaway family of companies.
