Duker was born in Aukum, Hanover, Germany, in 1933, the son of Elizabeth and Gerhard Duker, a carpenter. When John Herman was still in elementary school, his father died leaving Elizabeth with three sons to raise. Likely having relatives in the United States, in 1847 the mother with her three boys came to America, landing in New Orleans. From there the family took a boat to St. Louis, a city with a substantial German population, but soon after relocated to Quincy, Illinois, where Duker relatives lived.
Throughout the 19th Century, Quincy had grown from a backwater hamlet along the Mississippi River to become one of Illinois’ most important cities and ports. Quincy was a thriving transportation center as riverboats and rail service linked the city to many destinations west and along the river. It was on its way to becoming Illinois' second-largest city, surpassing Peoria in 1870. A number of German immigrants had made it their home.
Required to earn a living to help support the family, continuing his education in America was out of the question for John Herman. Reported, however, to have been “ambitious, determined, and resolute,” the youth apprenticed with a saddle-maker. Within a few years he had mastered the trade to the point where, with a partner, he was able to open a harness and saddlery store. In 1959, still only 26 years old, Duker sold out and with his brother, Theodore, opened a grocery, one that featured liquor.
In the meantime, John Herman was having a personal life. In Quincy he met Clara Elizabeth Glass, born in the city, and the daughter of Margaret and Simon Glass, a blacksmith, bricklayer and later saloonkeeper. Both were German immigrants. When John Herman and Clara married, he was 23 and she was 20. Over the next 18 years the couple would have ten children, six of whom lived to maturity.

In time John Herman Duker expanded into other business ventures. Of him, a biographer noted: “He was a man of excellent business ability and executive force, capable of controlling extensive interests, for he possessed sound judgment and keen discrimination.” His significant wealth resulting from liquor sales now was available for investment. As a consequence Duker became the primary stockholder and founding president of the First National Bank of Quincy, a post he held until his death. Shown here is one of the institution’s banknotes.

As he watched his children grow up and attend school, Duker must have thought back on his coming to Quincy and being denied by circumstances to complete his own education. The schools became his passion. He determined to join the School Board, an elected body in Illinois. The Illinois Constitution grants boards of education wide latitude in governing their school districts. Duker saw an opportunity to contribute to the schooling of Quincy’s youngsters, ran for School Board and was elected.
Education underwent many changes in the late 1800s, including the widespread adoption of the German kindergarten model and the establishment of trade schools. Schooling was understood as not just a privilege for the rich but increasingly a system to prepare children of all economic backgrounds to become contributing American citizens. By the end of the century, students in each grade were expected to learn specific skills in common during the school year. Textbooks were standardized, ensuring that a fourth-grader in one region of the country learned approximately the same things as a fourth-grader elsewhere.
Many of these innovations were adopted or expanded during Duker’s school board service. A forward thinker who prized education as he did, John Herman was open to new ideas and to broadening the learning process. Hailed as “deeply interested in the public school system…,” the people of Quincy elected him time and again to the board. In all Duker gave an astounding twenty-five years of service to the schools.
When he died in November 1903 at age 77, Duker was mourned in Quincy as a pioneer, business leader, educator and community-minded citizen. After a funeral at St. Boniface Catholic Church, he was interred in Block 1, Lot 132, of the parish cemetery. The Duker monument is shown below, along with his headstone, front left. The liquor house continued to bear his name, managed by Theodore Duker and other family members, until closed by National Prohibition in 1920.
A biographer aptly has encapsulated John Herman Duker’s life: “His history is notable in that he arose from a humble financial position to one of affluence and his progress was due entirely to his persistent and well directed effort, for reliable business methods and unfaltering purpose.”
Note: Although this post was gathered from multiple sources, the principal one was “Past & Present of the City of Quincy & Adams County, Illinois,” by Hon. William H. Collins and Cicero F. Perry, Chicago, 1905. All quoted material in italic is from that source. Photos of the Duker store and home are from the collection of the Quincy Public Library.
Nice piece. The Duker family also had a successful department store on Maine St. for a long time. (Some corrections to years listed need to be made.)
