A Long Standing Tradition…

The Michelmann Companies (Michelmann Steel Construction Company and Mid-States Door & Hardware) had their beginnings in 1865 when a Prussian immigrant named J.H. Michelmann started a small boiler and tank shop in Quincy, Illinois. He was a hard-working family man with, eventually, ten children to support and firm ideas on how to run a business. He believed in a quality product, on-time delivery and superior customer service.

J.H. passed his company and his beliefs on to his son-in-law William F. Gerdes Sr. From there the management of the business passed to his grandson Clarence A. Gerdes and to his great-grandson William F. Gerdes III.

Today, many years after its founding by J.H. Michelmann, the company is being run by his great-great-granddaughter Laura Gerdes Ehrhart utilizing the exact same ideals with which he started the business in 1865 – a quality product, on-time delivery and superior customer service.
