Transforming How the World Builds Through Off-Site Technologies

Our History

MiTek's History - Sepia photo of John Calvin Juriet from the 1950s


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.

Jureit founded Gang-Nail Systems, Inc., a company that stamped the metal connector plates, changing how roof trusses are built, making construction more scalable and housing more affordable.

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

Computer-based truss programs are written on IBM cards, and customer jobs are keypunched onto additional machine-reading cards, beginning the rise of digital construction design.


Moehlenpah Industries Inc. becomes Hydro-Air Engineering. Truss software is installed on a General Electric mainframe and accessed by customers through remote design terminals, allowing them to select from dozens of standard designs or enter custom geometries.

MiTek's History - Newspaper clipping of story about Paul Cornelson buying a portion of Hydro-Air Engineering


During one of the housing’s deep recessions, Paul Cornelson, then Vice President of Ralston Purina, acquires Hydro-Air Engineering from the Moehlenpah family. As Cornelson considers the truss software and technology’s role in its value to customers, he creates a new identity to bring technology into the company name. As such, he forms the parent company, MiTek Industries, Inc., and becomes Chairman & CEO.


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

MiTek 2000 (later renamed MiTek 20/20) becomes the first native Microsoft Windows truss design program for component manufacturers, changing the direction of software within the homebuilding industry.


Gang-Nail Systems and Hydro-Air Engineering operating companies merge as MiTek Industries, Inc., and go to market as one brand, MiTek.

On the verge of being sold off by Bowater, PLC, Gene Toombs, then MiTek Chairman, President, and CEO, calls and sends a letter to Warren Buffett of Berkshire Hathaway to discuss the possible acquisition of MiTek. On July 31, 2001, MiTek became a member of the Berkshire Hathaway family of companies.
