H.H. Barnum Company takes great pride in its history, and a continued legacy of placing customers and employees as a priority for over 60 years. In 1946, Herb Barnum founded the company with operations focused on process control valves and instrumentation. After ten years, former World War II bomber pilot and University of Illinois alumnus Ken Koza joined Barnum as a salesman, bringing with him a relentless work ethic and experience as an engineer at industrial control and thermostat manufacturer, Honeywell.


After quickly earning his place as a top salesman, Koza purchased 40 percent of Barnum, eventually taking on full ownership of the company following Mr. Barnum’s retirement in 1975. Koza, soon joined by his sons, Ed and Ken Junior, refocused business efforts from control valves and instrumentation to the distribution of factory automation systems across multiple industries

At the time of Ken Koza’s retirement in 1988, Barnum stood poised for growth with 12 employees and an opportunity to provide manufacturers with thoughtful industrial solutions and a detailed knowledge of automation controls. Today the company proudly employs over 130 people, operating a 65,000 square foot facility in its Brighton, Michigan Headquarters and stocking offices in Cleveland, Ohio and Grand Rapids, Michigan.

Dedication to innovation and quality by both our valued customers and employees is the foundation on which Barnum is built, and has remained a driving force behind the company since its humble beginnings over six decades ago.
